Water Cherenkov Detector Array (WCDA) in the Large High Altitude Air Shower Observatory has been proposed to survey gamma ray sources. The WCDA consists of 3600 Photo-Multipliers (PMTs) under water and the signals of PMTs would vary from 1 photo electron (P.E.) to 4000 P.E. In this paper, we propose an analogue front-end Application Specific Integrated Circuit (ASIC) prototype which is fabricated...
A base board for photomultiplier tube (PMT) with multi-dynode readout has been developed for the BGO electromagnetic calorimeter (ECAL) of the Dark Matter Particle Explorer (DAMPE). In order to cover a high dynamic range of energy measurements, the signals are read out from different sensitive dynodes 2, 5, and 8 (Dy2, Dy5 and Dy8). The performance of this new type of base board is studied with a...
The Dark Matter Particle Explorer (DAMPE) is a scientific satellite designed to search for the clue of dark matter particles for a mission period of at least 3 years. Two types of readout ASICs, named VA160 and VATA160, are adopted for the front-end electronics (FEE) to meet the design specification. Total lot screening of VA160 and VATA160 is utilized to assist in achieving levels of quality and...
