Member Function Documentation

constructCADdynodeSystem()

void OMSimPMTConstruction::constructCADdynodeSystem ( G4LogicalVolume *  p_mother )

private

Construction & placement of the dynode system entrance for internal reflections. Currently only geometry for Hamamatsu R15458.

Parameters

p_mother

LogicalVolume of the mother, where the dynode system entrance is placed (vacuum volume)

constructCathodeBackshield()

void OMSimPMTConstruction::constructCathodeBackshield ( G4LogicalVolume *  p_PMTinner )

private

Creates and positions a thin disk behind the photocathode volume in order to shield photons coming from behind the PMT. Only used when internal reflections are turned off.

doubleEllipsePhotocathode()

G4VSolid * OMSimPMTConstruction::doubleEllipsePhotocathode ( G4String  p_side )

private

Construction of the frontal part of the PMT following the fits of the technical drawings. PMTs constructed with doubleEllipsePhotocathode were fitted with two ellipses.

Returns

bulbSolid the frontal solid of the PMT

ellipsePhotocathode()

G4VSolid * OMSimPMTConstruction::ellipsePhotocathode ( G4String  p_side )

private

Construction of the frontal part of the PMT following the fits of the technical drawings. PMTs constructed with ellipsePhotocathode were fitted with an ellipse.

Returns

bulbSolid the frontal solid of the PMT

fullBulbConstruction()

std::tuple< G4VSolid *, G4VSolid * > OMSimPMTConstruction::fullBulbConstruction ( G4String  p_side )

private

Construction of the basic shape of the PMT for a full paramterised PMT. This is needed if internal reflections are simulated.

Returns

tuple of G4UnionSolid (the outer shape) and G4SubtractionSolid (the photocathode volume part)

getBulbSolid()

std::tuple< G4VSolid *, G4VSolid * > OMSimPMTConstruction::getBulbSolid ( G4String  p_side )

private

The basic shape of the PMT is constructed twice, once for the external solid and once for the internal. A subtraction of these two shapes would yield the glass envelope of the PMT. The function calls either simpleBulbConstruction or fullBulbConstruction, depending on the data provided and simulation type. In case only the frontal curvate of the photocathode has to be well constructed, it calls simpleBulbConstruction. fullBulbConstruction constructs the neck of the PMT precisely, but it needs to have the fit data of the PMT type and is only needed if internal reflections are simulated.

Returns

G4double the maximal radius of the frontal part of the PMT.

getPMTSolid()

G4VSolid * OMSimPMTConstruction::getPMTSolid

)

Returns

the solid of the constructed PMT.
