Conventions
The CLAS Large Angle Calorimeter is composed of
two pyramidal trunk shape modules which scintillators
stack are focused on the target point.
The scintillators stacks are numbered in the following way for one module (remember that each module is divided in an inner part which is nearer to the target point and an outer part):
- Inner Left Long (ILL) 1-24
- Inner Left Short (ILS) 1-40
- Inner Right Long (IRL) 1-24
- Inner Right Short (IRS) 1- 40
