// Class description:
|
|
//
|
|
// Represents many touchable detector elements differing only in their
|
|
// positioning. The elements' positions are calculated by means of a simple
|
|
// linear formula, and the elements completely fill the containing mother
|
|
// volume.

// G4LogicalVolume *pLogical,

// G4LogicalVolume *pMother,
|
|
// const EAxis pAxis,
|
|
// const G4int nReplicas,
|
|
// const G4double width,
|
|
// const G4double offset=0);
|
|
//
|
|
// Replication may occur along:
|
|
//
|
|
// o Cartesian axes (kXAxis,kYAxis,kZAxis)
|
|
//
|
|
// The replications, of specified width have coordinates of
|
|
// form (-width*(nReplicas-1)*0.5+n*width,0,0) where n=0.. nReplicas-1
|
|
// for the case of kXAxis, and are unrotated.
|
|
//
|
|
// o Radial axis (cylindrical polar) (kRho)
|
|
//
|
|
// The replications are cons/tubs sections, centred on the origin
|
|
// and are unrotated.
|
|
// They have radii of width*n+offset to width*(n+1)+offset
|
|
// where n=0..nReplicas-1
|
|
//
|
|
// o Phi axis (cylindrical polar) (kPhi)
|
|
// The replications are `phi sections' or wedges, and of cons/tubs form
|
|
// They have phi of offset+n*width to offset+(n+1)*width where
|
|
// n=0..nReplicas-1
|
|
|
|
// History:
|
|
// 29.07.95 P.Kent First non-stub version
|
|
// 26.10.97 J.Apostolakis Added constructor that takes mother logical volume
|
|
// 16.02.98 J.Apostolakis Added copy number
