Detailed Description

this class is intended to hold helper functions for doing things nonspecific in the geant repo methods will likely be static making it more akin to a namespace

getCloverRotationMatrix()

G4RotationMatrix NSDGeantHelper::getCloverRotationMatrix ( CloverInfo &  a_cloverInfo )

static

computes the rotation matrix for the clover a_inverseRot = true will return a rotation matrix to unrotate the clover

get position of 2 leafs on top of each other to adjust rotation angle

first rotation matrix to align clover with the rotation vector

the clover is free to rotate on its axis need to re-align the rotated vector from leaf3-leaf0 with the

vector from leaf3-leaf0 in unrotated geometry

getRotationMatrix()

G4RotationMatrix NSDGeantHelper::getRotationMatrix ( std::vector< double >  a_v1, std::vector< double >  a_v2 = {0,0,1}  )

static

this function returns the rotation matrix for rotation from the v2 to v1 the default argument is included to allow it to calculate the rotation from a default constructed object in the positive z dimension into a new arbitrary pointing vector. the vectors don't need to be normalized

placeClovers()

void NSDGeantHelper::placeClovers ( NSDG4::GeometryObject *  a_geoObject, G4LogicalVolume *  a_mother, ExperimentConfig &  a_config  )

static

same as above but for clovers

placeGeoObject()

void NSDGeantHelper::placeGeoObject ( NSDG4::GeometryObject *  a_geoObject, G4LogicalVolume *  a_mother, int  a_ID = 0  )

static

this function places a GeometryObject. It needs to have already been constructed, have a logical volume in it's store labled mother, and have it's approprite rotation matrix and location within the mother set in the base class

Parameters

a_geoObject	the object you would like to place
a_mother	the logical volume to place it in

placeOrgScintillators()

void NSDGeantHelper::placeOrgScintillators ( NSDG4::GeometryObject *  a_geoObject, G4LogicalVolume *  a_mother, ExperimentConfig &  a_config  )

static

this function takes an experiment config containing organic scintillators derives rotation matrices and location for them and places them in the supplied mother volume (regularly the world to aviod overlaps)

Parameters

a_geoObject	constructed right circular scintillator
a_mother	the logical volume to place it in
a_config	config containing a
