Detailed Description

Mandatory user initialization concrete class of G4VUserDetectorConstruction. It represents the whole geometry of the physical apparatus.

Definition at line 32 of file construction.hh.

Constructor & Destructor Documentation

◆ MyDetectorConstruction()

MyDetectorConstruction::MyDetectorConstruction ( )

Constructor of the class.

It defines the UI commands through DefineCommands() and gives default values to these settable variables: fIsLightGuide = false, nLightGuideMat = 1, fIsPCB = true and fIsEndcap = true. It also calls DefineMaterialsAndSurfaces().

Definition at line 7 of file construction.cc.

Member Function Documentation

◆ Construct()

G4VPhysicalVolume * MyDetectorConstruction::Construct ( )

override

Construct the detector geometry.

Depending on settings, it could call ConstructLightGuide(), ConstructPCB() and ConstructEndcap(). It uses the auxiliary function PositionSiPMs() for placing the SiPMs volumes and, at the end, it calls DefineVisAttributes().

Returns: The world physical volume physWorld.

Definition at line 178 of file construction.cc.

◆ PositionSiPMs()

void MyDetectorConstruction::PositionSiPMs	(	G4VPhysicalVolume *	physFrontSiPM,
		G4VPhysicalVolume *	physBackSiPM,
		G4int	row,
		G4int	col,
		G4int	index
	)

private

Auxiliary function called by Construct() for putting in the right position every SiPM.

Parameters

physFrontSiPM	The pointer to the physical volume of the SiPM to place on the front face of the scintillator
physBackSiPM	The pointer to the physical volume of the SiPM to place on the back face of the scintillator
row	The row of the SiPMs panel where the detector has to be placed
col	The column of the SiPMs panel where the detector has to be placed
halfCols	The integer half of the number of SiPMs in the row
index	The index number of the SiPM
