Abstract

The planned luminosity for the TEVATRON upgrade is ten times higher than at present (L~10³² cm^-2 s^-1) and involves a time between collisions as small as 132 ns. To operate the D0 muon system in this environment, completely new electronics is required for its 17500 proportional drift tubes. These electronics include a deadtimeless readout, a digital TDC with about 1 ns binning for the wire signals, fast charge integrators and pipelined ADCs for digitizing the pad electrode signals, a new wire signal triggering scheme and its associated trigger logic, and high level DSP processing. Some test results of measurements performed on prototype channels and a comparison with the existing electronics are presented
