抄録

A new readout electronics for the VENUS endcap liquid argon calorimeter was developed and has been operating for over a year at TRISTAN. The entire system was designed in such a way that gain of each readout channel could be calibrated to better than 1%. The system consists of 3840 channels of readout electronics. It employs hybrid charge sensitive amplifiers located in the 7.5kG magnetic field and TKO bus based electronics which consists of CR-(RC)4 filters, sample-and-hold circuits and 14bit ADCs. The energy resolution (σE/E for electromagnetic shower has been found to be 3.5% at 28GeV without any channel-by-channel gain calibration. The resolution was also determined to be σ E/E = 1.4% + 11.3%√E(GeV) from a large sample of 28 GeV Bhabha events and a small sample of e+ e → e+ e- γevents.
