slide13
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?

calibration module readout fibers and htr s
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.
