Abstract :
The ALICE Time-of-Flight system will be a large area ( 150 m 2 ) detector made by Multigap RPC (MRPC). The time digitisation is based on the High Performance TDC chip (HPTDC). Tests carried out on board prototypes are discussed, emphasising the optimisation of the effective time resolution of the chip when working in its Very High Resolution Mode. Lab bench tests and test beam results show that a 20 ps resolution has been achieved.
