1. 27 Oct. 2000TGC Simulation video meeting1 Trigger Simulation Hisaya Kurashige KOBE Univ.

2. 27 Oct. 2000TGC Simulation video meeting2 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

3. 27 Oct. 2000TGC Simulation video meeting3 Objective

4. 27 Oct. 2000TGC Simulation video meeting4 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

5. 27 Oct. 2000TGC Simulation video meeting5 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

6. 27 Oct. 2000TGC Simulation video meeting6 Schematic Electronics System “ Main ” class (management) Database Keep information of connection between modules ASD/Digi Detector simulation outputs Sector Trigger simulator

7. 27 Oct. 2000TGC Simulation video meeting7 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  R,  in a High Pt Board for muon tracks

8. 27 Oct. 2000TGC Simulation video meeting8 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

9. 27 Oct. 2000TGC Simulation video meeting9 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.

10. 27 Oct. 2000TGC Simulation video meeting10 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

11. 27 Oct. 2000TGC Simulation video meeting11 Migration on ATHENA/PESA scheme -2 Framework Change 1. Use TDS (Transient Data Storage) for Digitizer input (DICE Hit output equivalent) Digitizer output (RAW data equivalent) Trigger output (MUCTPI input equivalent) Test Vectors 2. Create/Use Detector Data Service For both trigger and detector simulation Geometry Connection Table
