LHCBGAUSS-876: Fixed Incorrect Rich1 Plane2Plane

RICH1 Profile Fix

Due to the position of Scoring Plane 1 meaning a clash in Geant4 volumes the RadLength test must be run in two stages. It was recently discovered that the results for Rich1 Plane-to-Plane radiation length profiles were incorrect due to VELO components also being included. To fix this the test is now run in three stages:

• Full geometry for producing cumulative radiation and interaction length profiles
• VELO only for Plane-to-Plane profile for the VELO + PuVeto
• No VELO and no PuVeto for all other Plane-to-Plane profiles

Updated Profiles

• For better resolution of 2D scans, the method for firing the particle gun has been switched from random to being an eta-phi grid where the number of events is determined by nStepsEta*nStepsPhi.
• Option for adding a cap to Z maximum of the interaction/radiation length profiles for Rich1 and Velo has been added to reduce saturation due to contribution from the beam pipe.

Other

• TNamed added for each plot as a description to be picked up by LHCbPR.
