Rough simulation plans...
Hello Everyone,
Here are a few notes about simulations. I'd appreciate
input from people about what work (and when) they are
doing. Any comments on the outline will be appreciated.
Thanks,
// Randy MacLeod

Hall-D Simulations requirements for the August 2000 Design Report.
Deadlines:
==========
August 2000: Next version of the CDR.
?Mid 2001: Full design report?
What simulation questions do we need answered by August?
What simulation questions do we need answered to write a full Design Report?
Overview of Simulation Goals:
=============================
- Signals
- physics/detector optimization
- vary resolutions of subsystems to see how it affects the PWA.
- Backgrounds - rates and spatial distributions,
- from collimators
- from EM in [empty] target.
- X-rays into drift chambers?
- cosmics?
Detectors: Study and Optimization:
==================================
- Beam - U Conn & JLab
- Geant MC of EM from target.
- Geant MC of collimators.
- Start counter - FIU
- Geant MC needed? Does FIU have a person to do the work?
- Tracking - CMU
- MCFast MC.
- Drift Cell Size
- Chamber geometry
- Role of dE/dx.
- Barrel Calorimetry - Norfolk/Regina
- Geant 3 simulations - Elliott Wolin has some code to start from.
- Particle ID - RPI
- What is needed?
- Forward Calorimetry - IU
- What is needed?
Short term work proposal:
Task: Who: Priority
========================================================================
Subsystem optimization each group. 1
Background and collimation Elliott Wolin & Randy MacLeod 1
Updated full detector MCFast Paul Eugenio and others 1
(cables, support, etc)
Make E852 Shower lib Paul Eugenio or Randy MacLeod 2
work with MCFast.
Event format Everyone 2
*****************************************************************************
In parallel to the work listed above, we need to start thinking about the
longer term development needs.
Complete Detector Performance:
==============================
Goal: Simulate (an hour/day/week/month of) data and analyze it.
Work Required:
- Event Generator
- known resonances
- non-q-qbar states.
- backgrounds
- Full MC - G3/4
- Physical Geometry
- Detector with housing
- Suport structures
- Cables
- Read-out Geometry.
-
- Digitization accuracy
- FADC algorithms.
- Trigger and DAQ
- Using the MC, determine Efficiency vs Energy.
- we can cut out the low energy events (2/3 of the events), prove it!
- Data Analysis software
