The initial concept of ALICE as defined in the Technical Proposal [1] mentions a set of MicroChannel Plate (MCP) detectors as the preferred solution to providing the Level 0 trigger and multiplicity information in the forward/backward regions (|h| > 1.5). The MCP option would have been a novel and elegant way to build a forward detector system, but it was realized that it would have required substantial funds and a major R&D effort and that, the desired functionality could be achieved with e...The initial concept of ALICE as defined in the Technical Proposal [1] mentions a set of MicroChannel Plate (MCP) detectors as the preferred solution to providing the Level 0 trigger and multiplicity information in the forward/backward regions (|h| > 1.5). The MCP option would have been a novel and elegant way to build a forward detector system, but it was realized that it would have required substantial funds and a major R&D effort and that, the desired functionality could be achieved with existing and proved technologies based on Cherenkov radiators, scintillators, and Si-strip detectors. This led to the division into the T0, the V0 and the FMD, for convenience named the Forward Detectors (FWD). These systems provide different functionalities, but also to some extent functional overlap and complementarity, which is considered an advantage for ALICE.Since then, work on the three sub-detectors has proceeded independently, although on issues such as integration, electronics, simulations, etc. there has always been good co-operation between the relevant detectors. Therefore, recognizing the common roots and the physical proximity of the modules and anticipating even closer collaboration in the future, it was decided to submit a joint Technical Design Report on the Forward Detectors (FMD, T0 and V0 TDR). » weiterlesen» einklappen
