the OO codes for endcap muon trigger simulation

• Hisaya Kurashige
• KOBE Univ.

2
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

3
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

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
Design

• Electronics System
• Main class (management)
• Database
• Keep information of connection between modules
• ASD/Digi
• Detector simulation outputs
• Sector
• Trigger simulator

7
Class Database

• Information used in simulation
• Cable Connection Table
• ASD --gt PP
• PP --gt SB
• SB --gt HPt
• HPt --gt Sector Logic
• Connection on PC board
• PP
• Coincidence map
• Mask information

8
Class Sector

• Simulate a trigger sector
• Describe trigger logics
• Consisits of PP, SB, HPt, and SL
• Timing manager controles multi-bunch signals

9
Class Slave Board

• Simulate a SB

Current Status -1

• Prototype Code was finished on Mar 00
• Simulate dR,df in a High Pt Board for muon tracks
• These are very preliminary results and we found
  some bugs exist

11
Current Status -2

• Comparison of simulation results with Yojis
  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/simula
  tion from one used in DICE.

Migration on ATHENA/PESA scheme

• Trigger Simulation is a algorithm in ATHENA
  framework
• 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
