THE TIMING AND CONTROL-SYSTEM OF THE ZEUS TRACKING DETECTOR DATA-ACQUISITION ELECTRONICS

The very high spatial resolution required by the Zeus Tracking Detecto rs and the 96ns periodic interaction between protons and electrons of the Hera collider require real time Analogue Signal Digitization at 10 4MHz controlled reliably to tight tolerances. Maximum event readout ef ficiency, fast monitoring of run time errors and testability of front end electronics require pipelining, speed and flexibility. Such an ele ctronic Timing and Control System (TCS) is operational within three ma in inner detectors of the ZEUS detector and is presented in this paper .
