Totally closed alpha-energy spectrum measurement system

Abstract

The invention provides a totally closed alpha-energy spectrum measurement system. According to the measurement system, a sample treatment table, a special muffle furnace, an alpha sample vacuum chamber and a charge-sensitive preamplifier are arranged in a stainless steel glove box; a bias power supply, a computer and a data acquisition processor are arranged in another measurement operation room; information transmission between the bias power supply and data acquisition processor in the measurement operation room and the alpha sample vacuum chamber and the charge-sensitive preamplifier in the stainless steel glove box are achieved through cable connection. According to the totally closed alpha-energy spectrum measurement system, the operations of preparing, transferring and measuring samples are finished in a completely closed environment, and instrument control and data processing are operated remotely; shells and components of various parts in the glove box are made of high-performance and acid-corrosion-resistant materials, so that the service life is greatly prolonged. The totally closed alpha-energy spectrum measurement system is convenient to operate, low in noise and stable in performance and is suitable for alpha-energy spectrum measurement of highly toxic and highly radioactive special samples.

Description

technical field [0001] The invention belongs to the technical field of nuclear instrument development and nuclear radiation measurement, and specifically relates to a fully enclosed α energy spectrum measurement system. The invention is suitable for the α energy spectrum measurement of highly toxic and highly radioactive special materials, and the sample is completed in a completely closed environment. preparation, transfer and measurement. Background technique [0002] At present, although there are many manufacturers at home and abroad that can provide various types of α energy spectrum measurement systems, these α energy spectrum measurement systems are all integrated with the body, and their operation is completely open, and can only be used for small quantities. Tiny weak radioactivity measurements. For the α energy spectrum measurement of highly toxic and highly radioactive special materials, the preparation, transfer and testing of the samples must be carried out in ...

AI Technical Summary

Problems solved by technology

For the α energy spectrum measurement of highly toxic and highly radioactive special materials, the preparation, transfer and testing of the samples must be carried out in a special completely closed environment to prevent radiation damage to the human body and harm to the environment, while the commercially available The α energy spectrum measurement system is far from meeting this requirement
