摘　　要：Purpose In order to avoiding the potential radiation harm caused by X-ray tube to the crew,and meeting the testing requirements for WLSF pad of Calorimeter Cell in the High Energy cosmic-Radiation Detection facility(HERD).Method Designed a testing system,which is composed by LED,LYSO crystal,and narrow bandpass filter.The stability of the testing system is validated by conducting long-term measurements of signal amplitudes using a PMT waveform sampling module.Results and conclusions The result showed that the deviation levels of the WLSF Pad’s light output test results are all less than 5%.The linear relationship between the results of testing system and the results obtained with the cosmic ray test has demonstrated the effectiveness of the testing system,which promises the further application in large-scale WLSF pads performance testing.
