Gamma-ray total absorption facility(GTAF)is composed of 40 pieces of BaF_2 detector,which will be used to accurately measure the neutron capture cross section in the energy range of keVMeV.The pulsed signals from the detectors were acquired by FlashADC.Fig.1 shows various pulsed waveform signal from BaF_2 detector,in which gamma rays of~(137)Cs and~(60)Co are effective,electronic noise and alpha particle are the background.
Gamma-ray total absorption facility (GTAF) is composed of 40 pieces of BaF_2 detector, which will be used to accurately measure the neutron capture cross section in the energy range of keVMeV. Pulsed signals from the detectors were acquired by Flash ADC. Fig. 1 shows various pulsed waveform signals from BaF_2 detector, where γ gamma rays of ~ (137) Cs and ~ (60) Co are effective, electronic noise and alpha particle are the background.
