Baffles Design
Designing baffles from ray traces requires GEMC runs without baffles, but detectors at the baffle z positions.
We define as fixed number of blocks which expand over a radius that will accept the full angular range from the whole target. Each block then has a range in phi, which we fit:
These are then considered, for each block over all baffles, to carve out an opening which does not allow particles below a momentum from making it through. There is a maximum opening which is defined from the number of sectors, along with a minimum "dead zone" which prevents photons.
