Abstract

The planned luminosity for the 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 in this environment, completely new electronics is required for the 17500 proportional drift tubes of the system. 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
