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 ...
