Detailed Description

Sensitive detector implementation to record G4 hits in the Tgc detectors.

The ProcessHits hook is called by Geant4 if the track enters a sensible Rpc gas gap volume. The TouchableHistory is used to deduce the associated readout element and then to identify the actual gas gap. The hit is then passed to the MuonSensitiveDetector class for event record

propagateAndSaveStrip()

Records the G4Step in the sim hit.

Hits are usually expressed at the center point of the step. Except for low-energy electrons where the endpoint of the random walk path is just extended

Parameters

hitId	Identifier of the gas gap or the tube in which the hit is recorded
toGaGap	Transform from the ATLAS global coordinates into the sensitive volume
hitStep	Step from which the particle's information and the pre and post step positions are fetched

Fetch the step end-points

Hit direction as the momentum direction

Electrons randomly work through the gas instead of drifting through the gas -> take the prestep of the first snap shop inside the gas as pre step point
