  1. Run IIb Trigger Simulation Report Mike Hildreth & Ela Barberis for the Run IIb Trigger Simulation Group Mike Hildreth – DØ Collaboration Meeting

  2. 3. L1CalTrk - completely new Simulation Components 1. L1Cal - Completely new capabilities - new architecture 2. L1CTT - “Drop-in” replacement - same architecture 4. AFEII - potentially more powerful (offline) - potentially cleaner trigger thresholds (online) Mike Hildreth – DØ Collaboration Meeting

  3. Run IIb Simulation Status • L1CAL: • introductory version of code which runs in Trisgim framework • “sliding windows” algorithm implemented for • jets • electrons (includes isolation algorithm, E/H) • hadronic taus? (includes isolation, E/H) • produces “object-level” tuple for analysis Mike Hildreth – DØ Collaboration Meeting

  4. Run IIb Simulation Status • L1CTT: • Existing simulation uses “old” L1CTT Equation format and runs in Trigsim framework • can only run one pT bin at a time • produces “object-level” tuple for analysis • Will be upgraded (soon) to take LVDT equations directly, run all 4 pT bins • insertion back into Trigsim will be much easier Mike Hildreth – DØ Collaboration Meeting

  5. Run IIb Simulation Status • L1TrkCal: • code being modified from existing L1Muo tools • architecture/uses completely open at this point • detailed simulations of L1CTT and L1CAL needed to decide what decisions are useful in L1TrkCal Mike Hildreth – DØ Collaboration Meeting

  6. Run IIb Simulation Status • New round of MC events being generated • (last set was p11) • p15, as-built CFT geometry • 7.5 poisson average minbias (~2E32@396ns) • QCD samples at varying pT (~200k events) • nearly done • Signal samples specified by physics groups • done soon These events will allow us to define L1 Trigger Terms over the coming months (First shot by ~summer) Mike Hildreth – DØ Collaboration Meeting

  7. Run IIb Trigger Studies Plan • At this time, we plan to incorporate L1MUO with the Run IIb versions of L1CTT, L1CAL, L1TrkCal in a single framework job (may or may not be Trigsim) • “object” tuples will be produced for each event • allows cross-correlation of trigger objects to correctly calculate combined efficiencies/rejections • rate estimates from background QCD samples • Performance on Physics Signals will lead to a new set of L1 Trigger Terms that will need to be implemented when the new triggers are installed • analyzers from Physics Groups Needed • more flexibility in the trigger hardware design than the number of terms in the L1 Trigger Framework! • some winnowing will be necessary… Mike Hildreth – DØ Collaboration Meeting

  8. AFE II Studies Preliminary Work: 1. Determination of CFT light yield from Data (~Done) - needed as input to realistically model improvements/effects from: -- radiation damage -- rate-dependence of VLPC gain -- gains from tighter thresholds with AFE II 2. Implementation of realistic light yields, threshold and gain distributions in MC - almost finished now with results of Data studies - will have correct distributions of gains, thresholds, etc., which can be varied to match current and future CFT Mike Hildreth – DØ Collaboration Meeting

  9. AFE II Studies 3. Tests of new AFE II capabilities - timing  z measurement (Demonstrated x2 faster code!) - cluster splitting, etc. (not done yet) - demonstration of “Physics case” for baseline b-tagging analysis (not done yet) Comment: hardware issues with current AFE performance at high data rates may be the dominant factor in AFE decision… Mike Hildreth – DØ Collaboration Meeting
