  1. SMT_real2mc package • Alex Koubarovski • Framework package smt_real2mc is intended to produce SimSMTHitChunk from SmtDataChunk. • For SMT SimTkHit list looks like: • SimTkHit* ptrtkhit = new SimTkHit ( • iord      // hit number-999    // MC id of particleiv         // volume index array0.         // golbal x0.         // global y0.         // global z0.         // global px0.         // global py0.         // global pz0.         // step777      // g3codestripn  // xin -> strip numberpulse   // yin -> adc count0.         // zin0.         // xout0.         // yout0.         // zout-1000. // edep0.         // tofdetid    // detector id ) • Those hits are marked as fake (similar to Mike Hildreth's cft_real2mc proposal) by unique GEANT code (777), MC particle ID (-999) and negative energy deposition (-1.0 GeV). • Volume index arrayiv contains the information about the detector the hit came from (barrel, layer, ladder, view or disk, wedge, view). • SmtTkHit has encoded detector information (detid).

  2. SmtDigiReco Loop over hits SimTkHit iv, de/dx Digitize the hit Fake hit Add noise to cluster itk = 9999 itk = -999 Add noise to the hit ladder/wedge itk = 9990 detid, stripn, pulse Create SmtDataChunk Add noise to the rest of SMT

  3. SmtDigiReco “to do” list • rcp switch to select between noisy channel map generation and reading a real one • interface to read a noisy/dead channel maps (ascii files) • make a real noisy channels map from SmtExamine (ascii file) • realistic distribution of the noisy channel noise (from SmtExamine)
