Tuesday Oct 5, 2004 Today was the first day of the 25ns structured beam. In the past week the five chambers have been tested and timed in. The original set-up with which we ended our X5a test in June'04 has been used as the base-line system. Four chambers, two peripheral crates with scintillator and TrackFinder triggers. In the 2nd half of the week we have added the ME1/1 chamber mounted on the HCAL and distributed the peripheral electronics (TMB/DMB) over four crates. Besides the addition of chambers and peripheral crates we also installed the FED crate which has one DDU and one DCC and replaces the previous DDU which was located in one of the peripheral crates. -Frank
