  1. INGRID ElectronicsOpen Issues Alfons Weber LLR March 20, 2008

  2. Electronics Status • TFB Production just launched • only minor changes to prototypes • DC coupling of LVDS links • 10+750 boards • Pre-production batch in ~ 2-4 weeks • Full production on schedule for start May • 200 / month • MCM/SCM/RMM/CTM • schematics almost finished • layout to be finished in ~4 weeks • first boards around May/June • production fast (~50 boards) • tight schedule

  3. System Integration (INGRID) CTM Trigger Primitives 100 MHz trigger trigger trigger GPS & beam MCM RMM0 Clk & trg data TFB0-47 100 MHz Clk & trg data RMM1 TFB0-47 100 MHz Clk & trg data TFB0-47 RMM2 TFB: TRIP-t front-end boardRMM: r/o merger moduleCTM: global trigger moduleMCM: master clock moduleSCM: slave clock moduleFPN: front-end proc. node (PC)DCC: data concentrator cardCMB: crate master board Clk & trg data TFB0-47 RMM3 Gigabit/Ethernet CTM, MCM, RMM FPN opticalLVDS

  4. Two types of trigger single module pre-scale according to position (<1:256) top more bottom less useful for strip-to-strip pulse height, relative timing and efficiency calibration multi module take always useful for module to module timing calibration Cosmic Trigger (I)

  5. Cosmic Trigger (II) • Single CTM has to serve all of INGRID • max number of trigger TFBs: 48x4 = 192 • up to 11 = 192/17 TFBs / module can be included in trigger • What is the trigger algorithm ??? • Trigger Algorithm (after glass of wine) • TFB • Tracking plane (2-fold coincidence) • veto plane (no coinc. possible) • CTM • n out of 11 planes • Questions (still not answered) • noise rate? • efficiency? • use veto planes? • max trigger rate? 1 2

  6. Cosmic Tests on Surface • Simplified set-up • run original 1 module algorithm (whatever it is) • typical rate 20 Hz, after pre-scaling • Needs • real DAQ system • HV settings for each sensor Gigabit/Ethernet opticalLVDS CTM, MCM, RMM FPN CTM TFB: TRIP-t front-end boardRMM: r/o merger moduleCTM: global trigger moduleMCM: master clock moduleSCM: slave clock moduleFPN: front-end proc. node (PC) Trigger Primitives 100 MHz trigger trigger MCM RMM0 Clk & trg data TFB0-12 100 MHz

  7. TFB Power Supplies • Specifications • service 13 TFBs • used in INGRID (MCM, CTM, 4 RMMs) • used in Off-axis Detector (MCM, 3 SCM) • power requirements into TFB (put in some headroom) • 260 mA @ 1.7 V  4 A • 600 mA @ 3.1 V  10 A • 50 mA @ 3.8 V  1 A • 180 mA @ 5.5 V  3 A • slow control interface • TCP/IP who is in charge • Alain Debraine • Important • ground potential of TFBs, RMMs and CTM have to be identical (DV << 1 V)
