摘要
The next generation of high-luminosity experiments requires excellent particle identification detectors which calls for Imaging Cherenkov counters with fast electronics to cope with the expected hit rates. A Barrel DIRC will be used in the central region of the Target Spectrometer of the planned PANDA experiment at FAIR. A single photo electron timing resolution of better than 100 ps is required by the Barrel DIRC to disentangle the complicated patterns created on the image plane. R&D studies have been performed to provide a design based on the TRB3 readout using FPGA-TDCs with a precision better than 20 ps RMS and custom frontend electronics with high bandwidth pre-amplifiers and fast discriminators. The discriminators also provide time information thus enabling walk corrections to improve the timing resolution. Two types of frontend electronics cards optimised for reading out 64 channel PHOTONIS Planacon MCP-PMTs were tested: one based on the NINO AMC and the other, called PADIWA, on FPGA discriminators. Promising results were obtained in a full characterisation using a fast laser setup and in a Lest experiment at MAMI, Mainz, with a small scale DIRC prototype. (C). 2014 Elsevier B.V.
