Compact Muon Solenoid
S-LINK for HCAL Readout
DESCRIPTION
S-Link64 will be used by the Hadron Calorimeter (HCAL) group in CMS to transmit data from the HCAL data concentrators (DCC) to the data acquisition system. The DCC modules are being designed and built at Boston University. The HTR modules are being designed and built at University of Maryland and the HRC at University of Illinois, Chicago. The 9U-VME crate layout (24 total) is shown here:
A demonstrator stage will send data over S-Link32 from the DCC to a CPU in the VME crate running Red Hat Linux. The CPU will also read the same data over VME to check the integrity of the transmission. The demonstrator setup is shown below:
A variation of this setup will be used for radioactive source calibration tests to carried out at Fermilab and for the CERN test beam.
