A high-purity germanium gamma spectrometer device with wide-energy anti-kang electric refrigeration

Abstract

The invention discloses a high-purity germanium gamma ray spectrometer with wide-energy anti-compton electric refrigeration, which comprises a bottom plate I. A supporting plate I is arranged above the bottom plate I. The top of the supporting plate I is provided with a locking mechanism. The top of the locking mechanism is provided with a refrigerating device. The inside of the refrigerating device is provided with a detector. The top of the refrigerating device is provided with a lead chamber. The middle position of the top end of the bottom plate I is provided with a mounting plate I. The middle position of the bottom of the supporting plate I is provided with a mounting plate II. One side of the mounting plate I is provided with a spectrum analysis device. The top end of the mounting plate I is provided with two sets of fixing blocks I. The inside of each fixing block I is provided with a semi-tooth gear I. Each semi-tooth gear I is connected with one end of a connecting rod I. Theother end of each connecting rod I is provided with a movable block. The upper end of each movable block is provided with a second connecting rod II. The upper end of each connecting rod II is provided with a semi-tooth gear II. The high-purity germanium gamma ray spectrometer with the wide-energy anti-compton electric refrigeration has the beneficial effects that the height of the support plateII can be adjusted according to the height of a worker, so that the worker can conveniently adjust and replace the refrigerating device.

Description

technical field [0001] The invention relates to the technical field of gamma spectrometers, in particular to a high-purity germanium gamma spectrometer device with wide-energy anti-kang electric refrigeration. Background technique [0002] In the field of on-site gamma energy spectrum measurement, wide-energy anti-kang electric refrigeration high-purity germanium gamma spectrometers are usually used to scan or fix-point measurements on different types of measurement objects, in order to obtain the results of radioactivity or activity concentration of the object to be measured , it is necessary to obtain the efficiency conversion coefficient of the detector to be measured through experimental calibration or numerical calculation. Numerical calculation methods need to obtain more parameters. Most of these parameters are obtained through experiments or empirical formulas, which may introduce large uncertainties. The experimental calibration method is the most direct way to perf...

Problems solved by technology

However, it is inconvenient for the current high-purity germanium gamma spectrometer with wide-energy anti-condensed refrigeration to keep the height of the detector constant during use. It brings some inconvenience to the map spectrometer. The fixing method of the refrigeration device in the high-purity germanium gamma spectrometer is relatively simple through the existing wide-energy anti-kang electric refrigeration, which is not conducive to replacing or taking the detector, and thus affects the safety of the staff. work efficiency
