  12. HF HTR crates HCAL Fall meeting, Nov 11-13,`04

  13. 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

  14. Detector view of HO (rings -1 & -2) HCAL Fall meeting, Nov 11-13,`04

  15. Calibration module readout fibers and HTR’s There are at least three options for organizing the calibration readout. • keep Calibration readout in time with signal readout. • Results in having many half used HTR’s • 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. • 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.
