Detailed Description

Function Documentation

create()

void create	(	const GearDir &	content,
		G4LogicalVolume &	topVolume,
		G4LogicalVolume &	envelopeVolume
	)

create the Sensor geometry and assign the sensitive detector implementation.

As the sensors are inside the SVD envelope but outside the PXD envelope we have to give both, the top volume and the envelope volume so that the appropriate volume can be chosen dependind on the parameters

Parameters

content	pointer to the parameters
topVolume	top volume of the simulation
envelopeVolume	envelope volume of the pxd/svd
