The ALICE HMPID on-detector front-end and readout electronics

In the ALICE HMPID detector, Cherenkov photons are localised by measuring the charge induction on a MWPC cathode segmented into pads. Two ASICs have been developed: the Gassiplex07-3, which is an analogue 16-channels multiplexed front-end circuit dedicated to the readout of gaseous detector and the...

Description
Summary:In the ALICE HMPID detector, Cherenkov photons are localised by measuring the charge induction on a MWPC cathode segmented into pads. Two ASICs have been developed: the Gassiplex07-3, which is an analogue 16-channels multiplexed front-end circuit dedicated to the readout of gaseous detector and the Dilogic-3, a sparse data scan digital processor. The combination of multiplexed and parallel-pipelined architecture allows to store several events between two L2 trigger and to transfer the 32-bits data words at a rate of 80 Mbytes per second through an optical data link.
