CTTT

Summary of Operation

The CTTT board collects L1 data from each of the eight octants in the CTT system. Each incoming L1 record contains information about the number of tracks found, whether any tracks are isolated, the total number of hit fibers, etc.

Based on all this information the CTTT forms trigger terms and sends these trigger terms to the DZERO trigger framework. One example of a trigger term would be TTK(1,10) which is set to indicate that there was one (or more) tracks with a pT above 10 GeV.
