摘要
Abstract
This article introduced the parallel grid ionization chamber that used to meas-ure the αradioactivity,which had a independent vacuum system.The system was com-posed of main body of the chamber,gas-filled and electronics system.Energy resolution was 26 keV for 23 9 Pu,background was 10 counts for one hour from 4 MeV to 6 MeV en-ergy range,the stability of 24 hours was less than 0.5% .The chamber can measure the energy of nuclide and analyze the energy spectrum structure to identify nuclear.关键词
