          \t\t\t\t<br />\n
          This standard applies to semiconductor radiation detectors that are used for the detection and high-resolution spectroscopy of charged particles. The measurement techniques described were selected to be readily available to all manufacturers and users of charged-particle detectors. Some superior techniques are not included because the methods are too complex or require equipment (such as particle accelerators) which may not be readily available.<br />\n
          Test procedures for the associated amplifiers and preamplifiers are described in ANSI/IEEE Std 301-1988<br />\n
          The object of this standard is to establish standard test procedures for semiconductor charged particle detectors. These detectors are in widespread use for the detection and high-resolution spectroscopy of charged particles. It is desirable to maintain standard test procedures so that measurements may have the same meaning to all manufacturers and users. Not all tests described in this standard are mandatory, but tests which are used to specify performance shall be performed in accordance with the procedures described herein.

          The emphasis on the methods of measurement is to enhance sensitivity and improve accuracy by working around the limitations of the test instruments, particularly oscilloscopes that have only a visual display for readout. A null technique is used where possible, thereby reducing basic errors to the inaccuracy of a pair of precision resistors. When use of a bridge is inappropriate, such as in measurements of pulse height with an oscilloscope, the pulse is made to occupy a fixed amplitude and vertical position on the face of the cathode-ray tube (CRT). Some measurements require test instruments or fixtures not commercially available at this writing; circuit diagrams for their construction are given in the Appendix. It is not acceptable to make use of a standard nuclear instrument module to test the performance of an amplifier unless the errors introduced by that module can be corrected for or shown to be less than the error caused by the amplifier. Examples are the use of a crossover-pickoff module to measure crossover walk in a bipolar amplifier, and an MCA to measure nonlinearity and noise.

          These test procedures cover amplifier and preamplifier systems with linear pulse-shaping networks for use with semiconductor, scintillation, and proportional detectors in the spectroscopy of ionizing radiation. The object is to provide a common language and methodology for users and manufacturers of pulse-amplifier systems.<br />\n
          This standard supersedes IEEE Std 301-1976, IEEE Standard Test Procedures for Amplifiers and Preamplifiers for Semiconductor Radiation Detectors for Ionizing Radiation. Test procedures for associated detectors are described in ANSI/IEEE Std 300-1988 and ANSI/IEEE Std 325-1986. IEEE Std 194-1977 is a companion document for pulse-shape terminology.<br />\n

          The emphasis on the methods of measurement is to enhance sensitivity and improve accuracy by working around the limitations of the test instruments, particularly oscilloscopes that have only a visual display for readout. A null technique is used where possible, thereby reducing basic errors to the inaccuracy of a pair of precision resistors. When use of a bridge is inappropriate, such as in measurements of pulse height with an oscilloscope, the pulse is made to occupy a fixed amplitude and vertical position on the face of the cathode-ray tube (CRT). Some measurements require test instruments or fixtures not commercially available at this writing; circuit diagrams for their construction are given in the Appendix. It is not acceptable to make use of a standard nuclear instrument module to test the performance of an amplifier unless the errors introduced by that module can be corrected for or shown to be less than the error caused by the amplifier. Examples are the use of a crossover-pickoff module to measure crossover walk in a bipolar amplifier, and an MCA to measure nonlinearity and noise.

          New IEEE Standard - Inactive-Withdrawn.<br />\n
          Test procedures for X-ray spectrometers consisting of a semiconductor radiation detector assembly and signal processing electronics interfaced to a pulse-height analyzer/computer are presented. Energy resolution, spectral distortion, pulse-height linearity, counting rate effects, overload effects, pulse-height stability, and efficiency are covered.

          This document presents standard test procedures for semiconductor X-ray energy spectrometers. Such systems consist of a semiconductor radiation detector assembly and signal processing electronics interfaced to a pulse height analyzer/computer. Test procedures for pulse-height analyzers and computers are not covered in this document. Section is essentially tutorial. This standard is not intended to imply that all tests described herein are mandatory, but only that such tests as are carried out shall be performed in accordance with the procedures described herein. Companion documents to this standard are ANSI/IEEE Std 300-1982 [1], ANSI/IEEE Std 301-1976 [2], and ANSI/IEEE Std 325-1971 [3]. The list of symbols and the glossary were derived from those in the companion documents. Contrary to previous convention in the X-ray spectroscopy field, this document utilizes the characteristic energy E of the X-ray rather than its wavelength λ. This approach is consistent with the fact that the basic quantity measured by this type of spectrometer is the X-ray energy. A convenient conversion is provided by the relationship λ(m) = 12.4 · 10-10 E-1(keV) λ(A0) = 12.4 E-1 (keV)

          This document presents standard test procedures for semiconductor X-ray energy spectrometers. Such systems consist of a semiconductor radiation detector assembly and signal processing electronics interfaced to a pulse height analyzer/computer. Test procedures for pulse-height analyzers and computers are not covered in this document. Section is essentially tutorial. This standard is not intended to imply that all tests described herein are mandatory, but only that such tests as are carried out shall be performed in accordance with the procedures described herein. Companion documents to this standard are ANSI/IEEE Std 300-1982 [1], ANSI/IEEE Std 301-1976 [2], and ANSI/IEEE Std 325-1971 [3]. The list of symbols and the glossary were derived from those in the companion documents. Contrary to previous convention in the X-ray spectroscopy field, this document utilizes the characteristic energy E of the X-ray rather than its wavelength λ. This approach is consistent with the fact that the basic quantity measured by this type of spectrometer is the X-ray energy. A convenient conversion is provided by the relationship λ(m) = 12.4 · 10-10 E-1(keV) λ(A0) = 12.4 E-1 (keV)

          New IEEE Standard - Inactive-Withdrawn.<br />\n
          Test procedures for X-ray spectrometers consisting of a semiconductor radiation detector assembly and signal processing electronics interfaced to a pulse-height analyzer/computer are presented. Energy resolution, spectral distortion, pulse-height linearity, counting rate effects, overload effects, pulse-height stability, and efficiency are covered. Test procedures for pulse-height analyzers and computers are not covered.<br />\n
          \t\t\t\t<br />\n
          This document presents standard test procedures for semiconductor X-ray energy spectrometers. Such systems consist of a semiconductor radiation detector assembly and signal processing electronics interfaced to a pulse height analyzer/computer. Test procedures for pulse-height analyzers and computers are not covered in this document. Section is essentially tutorial. This standard is not intended to imply that all tests described herein are mandatory, but only that such tests as are carried out shall be performed in accordance with the procedures described herein. Companion documents to this standard are ANSI/IEEE Std 300-1982 [1], ANSI/IEEE Std 301-1976 [2], and ANSI/IEEE Std 325-1971 [3]. The list of symbols and the glossary were derived from those in the companion documents. Contrary to previous convention in the X-ray spectroscopy field, this document utilizes the characteristic energy E of the X-ray rather than its wavelength λ. This approach is consistent with the fact that the basic quantity measured by this type of spectrometer is the X-ray energy. A convenient conversion is provided by the relationship λ(m) = 12.4 · 10-10 E-1(keV) λ(A0) = 12.4 E-1 (keV)

          This standard applies to the measurement of bulk properties of high-purity germanium as they relate to the fabrication and performance of germanium detectors for gamma rays and x rays. Such germanium is monocrystalline and has a net concentration of fewer than 1011 electrically active impurity centers per cm3, usually on the order of 1010 cm–3. Test and measurement procedures for fabricated germanium detectors are given in IEEE Std 325-1986 and IEEE Std 759-19<br />\n
          The purpose of this standard is to establish uniform procedures for measurements and analyses in the determination and reporting of bulk properties relevant to germanium radiation detector fabrication and performance. These properties are net electrically active impurity concentrations, |NA – ND|, the concentration of isolated defects with deep electronic levels NT, and certain crystallographic properties. The techniques described herein are those that have found general use in the industry, are practical, and provide verifiable and desired information to the detector fabricator.<br />\n

          This standard establishes methods for performance testing, calibration, and usage of thallium-activated sodium iodide [NaI(Tl)] detector systems for the measurement of gamma ray emission rates of radionuclides; the assay for radioactivity; and the determination of gamma ray energies and intensities. It covers both energy calibration and efficiency calibration. The following three techniques are considered:<br />\n
          a) Total spectrum counting (see 4.1) employs a system that counts all pulses above a low-energy<br />\n
          threshold (see 6.1, 6.2, and 6.3).<br />\n
          b) Single-channel analyzer (SCA) counting (see 4.2) employs a system with a counting “window,” which establishes upper and lower energy boundaries (see 6.1, 6.2, and 6.3).<br />\n
          c) Multichannel analyzer (MCA) counting (see 4.3) employs a system in which multiple counting windows are utilized. This technique allows measurements for which the continuum under the full energy peak may be subtracted without introducing unacceptable error.<br />\n
          In case of overlapping peaks in the spectrum, it is realized that an MCA with access to a spectrum-stripping program is necessary. Such cases are not covered by this standard.<br />\n
          The purpose of this document is to provide a standardized basis for the calibration and usage of sodium<br />\n
          iodide detector systems for the measurement of gamma ray emission rates of radionuclides. Typical applications include radionuclide identification and assay in various industrial, environmental, and medical applications. An NaI(Tl) detector system consists of three major components: a scintillating medium that produces a flash of light when ionizing radiation interacts with it; one or more photo multipliers, optically coupled to the scintillator, which converts the light flash to an amplified electrical impulse; and associated electronic instrumentation that powers the photomultiplier and processes the output signal. (See IEEE Std 398-1972. The theory of operation of NaI(Tl) detectors is presented in numerous publications, including [B3], [B5], and [B9] in clause 7

          This standard establishes methods for performance testing, calibration, and usage of thallium-activated sodium iodide [NaI(Tl)] detector systems for the measurement of gamma ray emission rates of radionuclides; the assay for radioactivity; and the determination of gamma ray energies and intensities. It covers both energy calibration and efficiency calibration. The following three techniques are considered:<br />\n
          a) Total spectrum counting (see 4.1) employs a system that counts all pulses above a low-energy<br />\n
          threshold (see 6.1, 6.2, and 6.3).<br />\n
          b) Single-channel analyzer (SCA) counting (see 4.2) employs a system with a counting “window,” which establishes upper and lower energy boundaries (see 6.1, 6.2, and 6.3).<br />\n
          c) Multichannel analyzer (MCA) counting (see 4.3) employs a system in which multiple counting windows are utilized. This technique allows measurements for which the continuum under the full energy peak may be subtracted without introducing unacceptable error.<br />\n
          In case of overlapping peaks in the spectrum, it is realized that an MCA with access to a spectrum-stripping program is necessary. Such cases are not covered by this standard.<br />\n
          The purpose of this document is to provide a standardized basis for the calibration and usage of sodium<br />\n
          iodide detector systems for the measurement of gamma ray emission rates of radionuclides. Typical applications include radionuclide identification and assay in various industrial, environmental, and medical applications. An NaI(Tl) detector system consists of three major components: a scintillating medium that produces a flash of light when ionizing radiation interacts with it; one or more photo multipliers, optically coupled to the scintillator, which converts the light flash to an amplified electrical impulse; and associated electronic instrumentation that powers the photomultiplier and processes the output signal. (See IEEE Std 398-1972. The theory of operation of NaI(Tl) detectors is presented in numerous publications, including [B3], [B5], and [B9] in clause 7

          Methods are established for performance testing, calibration, and use of sodium iodide detector systems for the measurement of gamma-ray emission rates of radionuclides, assay for radioactivity, and the determination of gamma-ray energies. Both energy calibration and efficiency calibration are covered. Three techniques are considered: total spectrum counting, which employs a system that counts all events above a low-energy threshold; single-channel analyzer counting, which employs a system with a counting window that establishes upper and lower energy boundaries; and multichannel analyzer counting, which employs a system utilizing multiple counting windows.<br />\n

          This standard establishes methods for performance testing, calibration, and usage of sodium iodide detector systems for the measurement of gamma-ray emission rates of radionuclides; the assay for radioactivity; and the determination of gamma-ray energies. It covers both energy calibration and efficiency calibration. The following three techniques are considered: (1) Total spectrum counting (see 5.1) employs a system that counts all events above a low-energy threshold (see 7.1, 7.2, and 7.3). (2) Single-channel analyzer counting (see 5.2) employs a system with a counting window which establishes upper and lower energy boundaries (see 7.1, 7.2, and 7.3). (3) Multichannel analyzer counting (see 5.3) employs a system in which multiple counting windows are utilized. This technique applies to measurements that do not involve overlapping peaks and those for which the continuum under the full-energy peak can be subtracted without introducing unacceptable error [4].<br />\n
          The purpose of this document is to provide a standardized basis for the calibration and usage of sodium iodide detector systems for the measurement of gamma-ray emission rates of radionuclides.<br />\n
          Typical applications include radionuclide identification and assay in various industrial, environmental, and medical applications. A sodium iodide detector system consists of: &quot;. . .three major components: a scintillating medium that produces a flash of light when ionizing radiation interacts with it; one or more photomultipliers, optically coupled to the scintillator, which converts the light flash to an amplified electrical impulse; and associated electronic instrumentation which powers the photomultiplier and processes the output signal&quot;. [See ANSI/IEEE Std 398-1972 (Reaff 1977), Test Procedures for Photomultipliers for Scintillation Counting and Glossary for Scintillation Counting Field.] The theory of operation of sodium iodide detectors is presented in numerous publications, including refs [1] - [3]
