  1. DESY test beam (DAQ integration, measurement plans, analysis) Mathieu Benoit

  2. Outline • DAQ Integration • M-i-M TLU Interface testing • Timepix Producer Status • TestBeamMeasurement plans

  3. M-i-M TLU • Man-in-the-Middle TLU Reader is a interface to the trigger logic unit used by the EUDET Telescope • Handle the handshake on each trigger with the telescope system , transmit Event Number and synchronizewith Timepix Producer via standard ethernetconnection • Handle the FITPixreadouttrigering and BUSY • Provide full digital control of Timepix Trigerring • Control throughethernetusing a simple dependence free, open Library • Compatible withmostlyany PMOD equipped FPGA Developpementboard • Reusable for CLICPixreadout, Timepix3 readout • Lowcost (~300 CHF) • Possibility for other Use • TDC (seenextslides) • Stand-Alone trigger interface to fitpix • Synchronisation studies (proposed by DESY) LVDS Signal for TLU I/O LEMO, TTL signal for spying TLU Signal and triggering TP FPGA Board

  4. M-I-M TLU TLU Timepix + FITPix Trigger Busy Trigger Clock ,BUSY TLU Reader, TDC, etc Microblaze (C code) PHY Communication to PC Trigger,Reset MIMTLU

  5. MIMTLU to increasetrack rate (Method 1) • MIMOSA26 only sensitive for 220 us, but isessentiallydead time free • Timepix canreadout out for arbitrary time, but long dead time (20-30 ms) MIMTLU can to scale the trigger rate sent to Timepix to keepshutter open for longer periods ~O(ms). • The producercanthensend data for many TLU trigger in one event, every X event. • Telescopestillsend data everyevent • Chunk of X telescopeevent are merged offline to match Timepix events • Advantage -> Increasetrackrate, disadvantage-> Weloose online monitoring Backup solution to increase trigger rate

  6. Modification to telescope to increasetrack rate (Method 2) • Mimosa26 actual readout actually read 100s of frame per trigger, throw most of them away and keep only two • I am looking into modifying the MIMOSA26 Labview Readout to change the number of frame kept per readout • Experts say it should be possible. • To be tested in the next TB period Preferred to increase trigger rate (until arrival of new TLU)

  7. MIMTLU as TDC 2.5kHz High-Precision Pulser • MIMTLU canhandle trigger up to 3.2kHz • Internalclock in FPGA MIMTLU running at 10 MHz • MIMTLU canbeused to providecoarse time stamping (~500ns over 10s) of trigger within Timepix Shutter • A CERN Open-Hardware TDC compatible with Spartan6 FPGA claim accuracy down to ~50ps!! AbsoluteResolution (over 2ms) Pulse-to-pulse timing (over 2ms)

  8. Measurement plan for June 2013 • Alignement Run, TelescopeOnly (1M Trigger, 1-2h) • Alignement Run, Telescope plus Timepix at 0 degree, TOT Mode (3h) • TOA RunwithVariousShutterlength/Clock (~ 1M Trigger, 0.5 day) • Optimization of Telescope plane distance (0.5 Day ) • High Track rate run, method 1 & 2 (1 day) • MIMTLU TDC Run/ CLICPixReadoutSynchronization tests (0.5,1 day) • Power PulsingRun (If DSG available) ~(1M trigger, 0.5 day) • ArrhusSpecificmeasurements (1-2 days)

  9. Lab issues • There has been issue withmaterialdisapearingfrom the Vertex lab • Euro/swissadapters • Lemo, scalpels, solderingequipement • USB cables • SolderingIronwasbroken and not fixed • Etc … • Woulditmakesense to ask for a wall to bebuilt to control access ? It wouldalsodefinebetter the protected zone (RP) • WithCLICPix/Timepix3 developpementcoming, itwouldbeuseful to have a second setup table for precisionmeasurement (for examplewithscintillatorfingersfrom DT, IR Lasers) • Melles griot has affordablelab table withBreadBoard for < 4500CHF
