Description

The Particle And Astrophysical Xenon Experiment III (PandaX-III) is an experiment to search for the Neutrinoless Double Beta Decay (NLDBD) using 200 kg radio-pure high-pressure gaseous xenon TPC with Micromegas detectors at both ends and cathode in the middle. A small-scale TPC equipped with 7 Microbulk Micromegas detectors is developed as the prototype detector. 128 channels are readout following an X-Y design with strips of 3 mm pitch (64 channels each direction) from one Micromegas module. Highly integrated front-end electronics composed of 4 front-end cards with 1024 readout channels is designed to readout the charge of Micromegas anode signals, digitize the waveform after shaping and send compressed data to back-end electronics. The cornerstone of the front-end electronics is a 64-channel application specific integrated circuit which is based on a switched capacitor array. The integral nonlinearity of the front-end electronics is less than 1% with 1 pC. The noise (RMS) of each readout channel is less than 0.9 fC with 1 μs peaking time and 1 pC range. Using the radioactive source 137Cs, joint-test of front-end electronics with the prototype TPC was carried out and the hit map of 7 Micromegas has been reconstructed.
