A Method for Determining First-Pass Fine Delays for the TRT Detector

description This note describes the method used to calculate the first-pass clock and trigger delays used for running the ATLAS TRT (Transition Radiation Tracker) during the commissioning period. Before the TRT can take useful data, these timing parameters need to be tuned such that the data for the correct event are read out, and such that that those data are well framed. This method is notable for the TRT in that it does not require iteration based on particle data, but rather is based on measured cable lengths. This method has been shown to align the TRT timing to within 5ns of the optimal timing, based on cosmic ray studies done in December of 2007.
