  1. Trigger Simulation Hisaya Kurashige KOBE Univ. TGC Simulation video meeting

  2. Objective • Simulate 1st level Trigger using TGC • As a part of MC production in ATLAS • to evaluate Trigger Performance • to filter events • For design of Trigger electronics • to evaluate Implementation of logic • to study Timing calibration and Diagnosis procedures TGC Simulation video meeting

  3. Objective TGC Simulation video meeting

  4. TGC Level-1 simulation • Input (same as current DICE) • Hit information of TGC chambers • Chamber number • Hit Position/Time • Momentum information of incoming particles • Output • Raw Data • Hit pattern of chambers • Trigger Information • RoI information to MUCTPI • Test vectors at each stage of trigger logic TGC Simulation video meeting

  5. Design policy • Detailed trigger simulation based on real electronics design • Can describe logic according to real implementation of ASIC • Can describe individual module • Can describe connection between modules • Can treat multi-bunch simulation TGC Simulation video meeting

  6. Schematic • Electronics System • “Main” class (management) • Database • Keep information of connection between modules • ASD/Digi • Detector simulation outputs • Sector • Trigger simulator TGC Simulation video meeting

  7. Current Status -1 • Prototype Code was finished by Daisuke and Koichi as a part of his master degree work on Mar ’00 • These are very preliminary results and we found some bugs exist dR,df in a High Pt Board for muon tracks TGC Simulation video meeting

  8. Current Status -2 • Now, a new student, Totsuka, takes over it supervised by Yoji, Kazumi and Yoji • Prof. Yu Fu helps us as a foreign researcher at ICEPP TGC Simulation video meeting

  9. Current Status -3 • Comparison of simulation results with Yoji’s results starts • But, there are some problems • It takes time for new students to understand TGC trigger scheme • We have changed TGC numbering scheme (sector No, chamber No etc.) for production/electronics/simulation from one used in DICE. It causes some troubles. TGC Simulation video meeting

  10. Migration on ATHENA/PESA scheme -1 • Trigger Simulation is a “algorithm” in ATHENA framework • Use Case Documents • Digitizer • Trigger Simulator • MC production • Diagnosis for electronics TGC Simulation video meeting

  11. Migration on ATHENA/PESA scheme -2 • Framework Change • Use TDS (Transient Data Storage) for • Digitizer input (DICE Hit output equivalent) • Digitizer output (RAW data equivalent) • Trigger output (MUCTPI input equivalent) • Test Vectors • Create/Use Detector Data Service • For both trigger and detector simulation • Geometry • Connection Table TGC Simulation video meeting
