HF HTR crates

HCAL Fall meeting, Nov 11-13,`04 HO? HO crates are divided into 90 degree segments, with each RM covering 15 degrees. A 90 degree slice across all HO rings requires 13.5 HTR’s. There are many possible ways to map RM fibers to HTR’s. Are there any patterns such as muon triggers… that require a particular mapping of HO signals?

HCAL Fall meeting, Nov 11-13,`04 Calibration module readout fibers and HTR’s There are at least three options for organizing the calibration readout. 1.keep Calibration readout in time with signal readout. –Results in having many half used HTR’s 2.Have calibration HTR’s in the crates with associated RBX signal HTR’s. –Calibration readout will be delayed in relation to signal. –Patching is not “modular”, best solved by dedicated calibration patch panel. –6 out of 8 fibers would be used in every HTR input. 3.Have all calibration HTR’s in dedicated crate. –Calibration HTR’s would not be on same partition as the associated RBX’s. –HTR’s could be fully utilized.
