Abstract
The BaF2 detector at CSNS-WNS (White Neutron Source at China Spallation Neutron Source) is a segmented 4π detector array for measuring (n, γ) cross sections, which is planned to have up to 92 channels finally. The detector system, consists of the BaF2 crystals and photomultiplier tubes, readout electronics, and the data acquisition system. To maintain as much information of the physical instances as possible, the full waveform digitization is used in the readout electronics. To meet the requirements of waveform digitization, the front-end signal conditioning method should have good performance of low noise, high bandwidth, low power consumption, etc. In this paper, the basic requirements for the front-end signal conditioning method are discussed. And then, the front-end signal conditioning method for the BaF2 detector is proposed. Some test results are also present, which shows the proposed front-end signal conditioning method is suitable for signal conditioning for BaF2 detector application.
