Sorting Devices for the CSC Muon Trigger System at CMS

The electronics system of the Cathode Strip Chamber (CSC) muon detector at the CMS experiment needs to acquire precise muon position and timing information and generate muon trigger primitives for the Level-1 trigger system. CSC trigger primitives (called Local Charged Tracks, LCT) are formed by anode (ALCT) and cathode (CLCT) cards [1]. ALCT cards are mounted on chambers, while CLCT cards are combined with the Trigger Motherboards (TMB) that perform a time coincidence of ALCT and CLCT. Every combined CLCT/TMB card (one per chamber) transmits two best combined muon tags to th
