CPT Week, Nov 2003, B. Paul Padley, Rice University5 MPC Design Status 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 Rice
CPT Week, Nov 2003, B. Paul Padley, Rice University6 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 University7 Beam Test With 2 CSC’s at X5a //
CPT Week, Nov 2003, B. Paul Padley, Rice University8 Beam Test Setup Peripheral Crate 2 DMB, 2 TMB 1 CCB, 1 MPC FED crate 1 DDU PC TTC crate DAQ Data Trigger primitives S1 S2 S3 beam CSC 1 CSC 2 Track Finder Crate TRIDAS 2 CSC’s, all on-chamber boards Up to 80K events read out in 2.6s spill
CPT Week, Nov 2003, B. Paul Padley, Rice University9 CSC Peripheral Crate From front-end cards Muon Port Card (MPC), which sends trigger primitives on optical links Clock & Control Board (CCB) with TTCrm
CPT Week, Nov 2003, B. Paul Padley, Rice University10 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 University11 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 University12 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 Noticed that CCB commands have 1 BX extra latency with TTCRq TTCRq
CPT Week, Nov 2003, B. Paul Padley, Rice University13 PLL Results Using either the home-built VCXO+PLL solution or the CERN QPLL solution for the 80 MHz reference clock to TLK2501 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 L1A
CPT Week, Nov 2003, B. Paul Padley, Rice University14 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 10K 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 University15 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.

CPT Week, Nov 2003, B. Paul Padley, Rice University18 Trackfinder crate at Rice Sector Processor CCB Sorter
CPT Week, Nov 2003, B. Paul Padley, Rice University19 Comprises: - Sorter “4 out of 36” based on 7-bit Rank - Output LUT - Input and output FIFO buffers for testing purposes - “Winner” logic - CCB interface - VME interface (A24D16 slave + Geographical Address) Based on Xilinx XC2V4000-5FF1152C, common mezzanine card with the Sector Processor Latency – 135 ns FPGA Design
CPT Week, Nov 2003, B. Paul Padley, Rice University20 Muon Sorter Status and Plans Have 4 boards in hand, one is stuffed (except backplane interface) Have a dedicated Wiener 9U crate with VME J1 backplane and custom Track Finder backplane installed Sector Processor – to – MS interface test currently underway
CPT Week, Nov 2003, B. Paul Padley, Rice University21 MilestonesMilestones 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 Rice
CPT Week, Nov 2003, B. Paul Padley, Rice University22 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
