6. 6 MUID Operation Reconstruct tracks in two orthogonal views; find maximum depth. Obtain precision momentum measurement from Muon Tracker.  rejection (10 -4 ) via momentum/depth discrimination. Struck bit pattern is LVL1 input (where steerable road algorithm is implemented).

7. 7 MUID Numbering 2 arms 5 gaps/arm 4 large, 2 small panels/arm Large panels –H: 118 tubes > 59 channels > 4 16-pair signal cables –V: 128 tubes > 64 channels > 4 16-pair signal cables Small panels –H: 90 tubes > 45 channels > 3 16-pair signal cables –V: 52 tubes > 26 channels > 2 16-pair signal cables MUID –H: 6520 tubes > 3260 channels > 220 16-pair signal cables –V: 6160 tubes > 3080 channels > 200 16-pair signal cables –6340 active channels, 6720 channels instrumented

10. 10 Iarocci Tubes

11. 11 MUID Readout Channel (2-pack) Halve readout channels Improves timing Eliminate geometrical inefficiency Add redundancy

12. 12 MUID FEE Requirements Integrating filter to reduce noise from large tube capacitance (500-1000 pF/channel). Capabilty to drive long cables (~20 m). All signals arrive within one beam clock cycle for LVL1. Only digital information (struck bit pattern) required. Longevity (!) for anything inside the panel.
