Abstract :
A multichannel TDC subsystem was designed and built at the Institute for Nuclear Physics at Mainz University. The system is based on a TDC ASIC chip called TDC 2001 and consists of several TDC modules housed in a VME-type crate. The TDC modules are controlled and read out by a transputer. The transputer can deliver the data through the transputer links to VME-systems, workstations, or PCs as data acquisition master. The subsystem, as it was developed for the A1 experiment at the MAMI accelerator in Mainz, is described, and first results from the operation at the experiment are given
