MPC Design Status Rice 3 boards were fabricated and assembled in summer 2002 Tested MPC standalone (sorter logic) and with one and two Trigger Motherboards and full-size custom backplane CPT Week, Nov 2003, B. Paul Padley, Rice University 5
UCLA Cosmic Ray Test Cosmic Ray tests were performed at UCLA in preparation for time structured test beam during spring 2003 CPT Week, Nov 2003, B. Paul Padley, Rice University 6

CSC Peripheral Crate From front-end cards Clock & Control Board (CCB) with TTCrm Muon Port Card (MPC), which sends trigger primitives on optical links CPT Week, Nov 2003, B. Paul Padley, Rice University 9
Test Performed Compare • MPC output LCTs stored in FIFO on MPC • TMB output LCTs extracted from DDU data List of checks • • Bit errors in data transmission Data acceptance from 2 TMBs Sending MPC winner bit to TMB Sorting of LCTs based on “Quality Bits” CPT Week, Nov 2003, B. Paul Padley, Rice University 10
Results from summer beam test During time structured beam in the summer the set of tests were repeated successfully Note this was using clock distribution from TTCmi->TTCvi->TTCrm on CCB Existing TTCrm adequate for Intracrate functionality. Also adequate for DAQ path (which uses crystal oscillators to clock links since they are asynchronous) However, MPC->SP communication failed. TTC Jitter one of the problems. CPT Week, Nov 2003, B. Paul Padley, Rice University 11
TTC QPLL Mezzanine card Three made available to CSC group for testing during Sept. 03 structured beam test Provides stable clock signals at 40, 80, and 160 MHz at correct LHC frequency Installed on Clock and Control Board (CCB) with 40 MHz clean clock sent to backplane and 80 MHz clock sent by twisted pair to SP and MPC TTCRq • Noticed that CCB commands have 1 BX extra latency with TTCRq CPT Week, Nov 2003, B. Paul Padley, Rice University 12
PLL Results Using either the home-built VCXO+PLL solution or the CERN QPLL solution for the 80 MHz reference clock to TLK 2501 receivers: • PLL locks to incoming machine clock • Measured frequency: 40. 078893(1) MHz • No errors on optical links reported over many hours of PRBS and data tests Data successfully logged by both CSC DAQ and CSC Track-Finder readout • SP data FIFO synchronized to L 1 A CPT Week, Nov 2003, B. Paul Padley, Rice University 13
TTCRq (QPLL) Test Results QPLL 80 MHz clock directly to MPC transmitters & home-built VCXO+PLL for SP receivers: • No link errors for 20 minute PRBS test QPLL 80 MHz clock directly to SP receivers and MPC uses default clock multiplier: • No link errors for 15 minute PRBS test • Successfully logged data for 10 K events (run 5151) QPLL 40 MHz clock on TF crate backplane and SP uses DLL in FPGA for clock multiplier: • Solution tried for Phase 1 (May) structured beam running • Link errors observed in PRBS test TTCRq on CCB in peripheral crate • Able to take data with same trigger efficiency (i. e. TTCRq works for peripheral crate electronics as well and is compatible with TTCRm) CPT Week, Nov 2003, B. Paul Padley, Rice University 14
Results from Sept Beam test Intracrate tests successfully repeated This time PLL patch was used to stabilize clocking of optical links in the trigger path MPC to SP communication now successful Last day of run got hold of TTCrq an again the test was successful.

Milestones Rice Sep-02 Prototype construction: • MPC done, • CCB done • waiting for new TTCrq, and will then redo • As a result of TTCrx Jitter problem need resdesign with TTcrq • Muon Sorter Done CPT Week, Nov 2003, B. Paul Padley, Rice University 21
More Milestones • Apr-03 Prototype testing done: Underway • Sep-03 Final designs done • MPC significantly delayed (until summer ’ 04) • Although MPC prototype was completed summer ’ 02, integration testing of it will not be completed until spring ‘ 04 • Oct-04 Production done • At risk given the final design schedule • Apr-05 Installation done CPT Week, Nov 2003, B. Paul Padley, Rice University 22
