Calibration System of Sensitivity for Pulsed Radiation Detector Based on LabVIEW

Abstract

In view of insufficiencies such as few datum and high individual error in traditional calibration experiment,a calibration system of sensitivity for pulsed radiation detector which controlled Keithley 6517A electrometer by GPIB-USB convertor was built based on LabVIEW. The calibration system can realize real-time current acquisition,analysis and storage,and can also achieve real-time sensitivity calculation. Moreover,it is able to store the condition and results of experiment at normalized format. Experimental results show that the system features good stability and reliability,high measurement and control precision which realizes expected functions and improves calibration precision.
