Beam test of a full-length prototype of the BESIII drift chamber with the readout electronics
Abstract
A full-length prototype of the BESIII drift chamber together with its readout electronics was built and a beam test was performed. Two different methods, namely "single-threshold method" and "double-threshold method" for timing measurement, were studied. Test results show that the BESIII drift chamber and its readout electronics can reach their design specifications. The "double-threshold method" results in a better timing accuracy and noise suppression capabilities as compared with the "single-threshold method".
