ACD Performance Tests
October, 2002
In preparation for Gleam v3
A number of ACD modifications have occurred over the past few months
including:
- A complete re-write of the AcdDigi algorithm, which optionally now
includes:
- Edge Effects
- Poisson Fluctuations
- Gaussian Noise
- Revision of AcdDigi TDS and ROOT classes
Still on the "to do" list:
- Geometry update
- Inclusion of ribbons in AcdDigi
- Update of AcdRecon TDS and ROOT classes
- Allow for random noise in ACD tiles that are not actually "hit".
A number of performance plots have been suggested:
Monte Carlo Tests:
- Demonstrate MIP distribution for 300 MeV muons both on and off axis.
Digi Tests:
- Demonstrate Edge Effects are functioning by creating a profile plot of (x,
y) position along a tile versus mean energy deposition after edge effects
have been applied.
- Show the inefficiency for an ACD tile using normal incident muons shot
into the center of a tile
- Reproduce Alex's efficiency plots for individual PMTs and using OR of PMTs
Recon Tests
- Produce reference plots for Active Distance for both normally incident 100
MeV muons and gammas
The fraction of gamma conversion should match expected compton-scattering in
an ACD tile.
Other Tests
- Demonstrate that the "well" is working
Shoot some large number of protons and find an event that produces a gamma
ray in the blanket.
- Backsplash...
