F1 - An Eight Channel Time-to-Digital Converter Chip for High Rate Experiments

摘要

A new TDC chip has been developed for the COMPASS experiment at CERN. Theresulting ASIC offers an unprecedented degree of flexibility and functionality.Its capability to handle highest hit and trigger input rates as well as its lowpower consumption makes it an ideal tool for future collider and fixed targetexperiments. First front-end boards equipped with the F1 chip have been usedrecently at testbeam experiments at CERN. A functional description andspecification for this new TDC chip is presented.
