//------------- G4MultipleScattering physics process -------------------------
|
|
// by Laszlo Urban, March 2001
|
|
//
|
|
// 07-08-01 new methods Store/Retrieve PhysicsTable
|
|
// 23-08-01 new angle and z distribution,energy dependence reduced,
|
|
// Store,Retrieve methods commented out temporarily, L.Urban
|
|
// 11-09-01 G4MultipleScatteringx put as default: G4MultipleScattering
|
|
// Store,Retrieve methods reactived (mma)
|
|
// 13-09-01 Unused TrueToGeomTransformation method deleted,
|
|
// class description (L.Urban)
|
|
// 19-09-01 come back to previous process name msc
|
|
// 17-04-02 NEW angle distribution + boundary algorithm modified, L.Urban
|
|
// 22-04-02 boundary algorithm modified -> important improvement in timing !!!!
|
|
// (L.Urban)
|
|
// 24-05-02 changes in data members, L.Urban
|
|
// 30-10-02 changes in data members, L.Urban
|
|
// 20-01-03 Migrade to cut per region (V.Ivanchenko)
|
|
// 05-02-03 changes in data members, L.Urban
|
|
// 28-03-03 Move to model design (V.Ivanchenko)
|
|
// 18-04-03 Change name (V.Ivanchenko)
|
|
// 16-06-03: ShortLived are not applicable any more (V.Ivanchenko)
|
|
// 17-08-04 name of data member facxsi changed to factail together
|
|
// with the corresponding set function (L.Urban)
|
|
// 08-11-04 Migration to new interface of Store/Retrieve tables (V.Ivantchenko)
|
|
// 15-04-05 optimize internal interfaces (V.Ivanchenko)
|
|
// 02-10-05 new algorithm for step limitation, new data members (L.Urban)
|
|
// 05-10-05 value of data member tlimitmin has been changed (L.Urban)
|
|
// 23-10-05 new Boolean data member prec (false ~ 7.1 like, true new step
|
|
// limit in TruePathLengthLimit, L.Urban)
|
|
// 25-10-05 prec renamed to steppingAlgorithm, set function triggers
|
|
// 'default' facrange too, true - 0.02, false - 0.2 (L.Urban)
|
|
// 26-10-05 the above is put in the function MscStepLimitation() (mma)
|
|
// 05-11-05 new data member rangecut (L.Urban)
|
|
// 13-11-05 some code cleaning (L.Urban)
|
|
// 07-12-05 GeomLimit is protected instead of public
|
|
// 11-12-05 data menber rangecut removed (L.Urban)
|
|
// 19-01-07 tlimitmin = facrange*50*micrometer, i.e. it depends on the
|
|
// value of facrange (L.Urban)
|
|
// 16-02-06 set function for data member factail (L.Urban)
