Objective
Simulate 1st level Trigger using TGC As a part of MC production in ATLAS
to evaluate Trigger Performance to filter events
On the frame of Athena
For design of Trigger electronics to evaluate Implementation of logic to study Timing calibration and Diagnosis
procedures Stand-alone environment

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

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

Current Status -1
Prototype Code was finished on Mar ’00 Simulate R, in a High Pt Board for muon tracks
These are very preliminary results and we found some bugs exist

Current Status -2
Comparison of simulation results with Yoji’s results starts
But, there are some problems Geometry in DICE is different from the final one We have changed TGC numbering scheme
(sector No, chamber No etc.) for production/electronics/simulation from one used in DICE.

Migration on ATHENA/PESA scheme
Trigger Simulation is a “algorithm” in ATHENA framework
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
