Abstract :
A newly designed multichannel (18 channel), multihit (<255), and multievent (<255) time-to-digital converter (TDC) system, consisting of discriminator- and TDC-modules, is described. The TDC with a time resolution of 10 ns is optimized for fast readout at high event rates. To achieve high-speed throughput, the system is built up in VMEbus for full 32-b data transfer in combination with powerful VME processor modules for data processing. All TDC modules in one VME crate can be read out by one block transfer
