  • ALCT - Anode Local Charged Tracks finding board. It is the part of the CSC Local Trigger electronics of the muon detectors of CMS experiment at CERN.









The ALCT board receives at 40 MHz anode signals from a Cathode Strip Chamber (CSC) and attempts to find hit patterns in the six - layer chamber using a multiple - layer coincidence timing technique, and then to identify the location and quality of the best two muon track stubs transiting the chamber.

A single ALCT board can accept all of the signals from an entire CSC.

There are 3 versions of the ALCT, having either 288, 384 or 672 channels that correspond to different CSC sizes.

Results from the muon pattern-finder logic are formatted into Local-Charged-Track data frames for each muon found. LCT frames are transmitted to the Trigger Mother Board (TMB) by 80 MHz data transfer interface.
