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