This standard applies to HPGe �� -ray detector performance testing, but also for high-purity germanium and germanium X-ray detector (Li) detector performance tests. GB/T 7167-2008: Test procedures for germanium gamma-ray detectors---This is a DRAFT version for illustration, not a final translation. Full copy of true-PDF in English version (including equations, symbols, images, flow-chart, tables, and figures etc.) will be manually/carefully translated upon your order.Test procedures for germanium gamma-ray detectors ICS 27.120 F88 National Standards of People's Republic of China Replacing GB/T 7167-1996 Germanium γ-ray detector test methods (IEC 60973. 1989, NEQ) Posted 2008-07-02 2009-04-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis corresponds to the standard IEC 60973. 1989 "germanium γ-ray detector test methods", and IEC 60973. 1989 for non-degree of consistency Equivalent. This standard replaces GB/T 7167-1996 "germanium γ-ray detector test methods." The main changes compared to 7167-1996 standard and GB/T as follows. --- Modify the terms and definitions of some of the energy resolution and detector window thickness (see this standard 3.16,3.17,3.25); --- Remove the germanium detector classification section (see Chapter 3 of the original standard); --- Modify the detection efficiency part (see Chapter 6 of this standard). The standard proposed by China National Nuclear Corporation. This standard by the National Standardization Technical Committee on nuclear instrumentation. This standard was drafted. China Institute of Atomic Energy. The main drafters of this standard. Yuan Daqing, Wei Kexin. This standard replaces the previous standard release case. GB/T 7167-1987, GB/T 7167-1996. Germanium γ-ray detector test methods1 ScopeThis standard specifies the performance test methods germanium γ-ray detectors. This standard applies to high-purity germanium γ-ray detector performance tests, but also for high-purity germanium detectors and X-ray Ge (Li) detectors Performance Testing.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard. JJG578-1994 germanium γ Spectrometer activity measuring device verification procedures JJG752-1991 germanium spectrometer γ activity standard means test procedures3 Terms and DefinitionsThe following terms and definitions apply to this standard. 3.1 At room temperature, the net electrically active impurity concentration of stable germanium crystal, the net impurity density is typically less than 3 × 1010cm-3. In appropriate bias , The detector consists of a conventional high-purity germanium crystal size can be made to achieve fully depleted. 3.2 Two electrical contact electrode surface of the semiconductor detectors are parallel. 3.3 Two electrical contact electrode surface of the semiconductor detector partially or fully coaxial. Generally, one end of the electrode is closed, called single Beginning coaxial detector. Two electrode terminals are not closed, the beginning called double coaxial probe. 3.4 The outer contact layer (outer electrode) is an N + type coaxial detector, the outer electrode forward biased. Because the detector crystal P-type high-purity germanium, Also known as the P-type coaxial detector. 3.5 The outer contact layer (electrode) is P-type coaxial detector, a negative bias is applied to the external electrode. Because the crystal detector using N-type high-purity germanium, also known as N-type coaxial detector. 3.6 Detector sensitive volume in the well-shaped electrode with a cylindrical hole coaxial. Measurement sample can be placed in the well, being sensitive area detector package ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 7167-2008_English be delivered?Answer: Upon your order, we will start to translate GB/T 7167-2008_English as soon as possible, and keep you informed of the progress.
