Full Description

Scope

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

Purpose

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.As an aid to the reader, an annex is included for background material. Paragraph numbers in the annex are prefixed by the letter A, while the numerical parts of the numbers correspond to those in the main body of the text to which they pertain.Not all tests described herein are mandatory; however, any tests that are intended to conform to this standard shall be performed according to its provisions.Mandatory procedures are designated by the word shall. Recommended procedures are designated by the words should or recommended. Optional procedures are designated by the word may.

Abstract

New IEEE Standard - Active.This standard applies to the measurement of bulk properties of high-purity germanium as they relate to 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 center per cm3, usually on the order of 1010 cm-3.
