Abstract
We present results of development of the fast Forward Multiplicity Detector (FMD) for ALICE at the future LHC. The UHV compatible UHF sector type detector prototype based on the application of the micro-channel plates (MCP) was designed and produced. The double MCP setup (gain 10 8) gives a strong signal for the UHF readout which includes also a multichannel passive summator which separates the fast and slow components of the signal providing the combination of individual pads charge readout, precise timing and analog multiplicity information. The status of the isochronous MCP disk development and the experimental tests are also discussed, including: • - model simulations of the FMD detector performance in heavy ion collisions at the LHC; • - tests of various FMD-MCP structures (small area prototypes and sector multipad prototype).
