// Description: Sets up particle beam
|
|
//
|
|
// By default 1 pi+ is shot from (0,0,0)
|
|
// in (1,1,0.1) direction at 100 GeV
|
|
// Use /gun/... commands to modify energy,origin,direction at run time.
|
|
// or/and
|
|
// /CCal/generator/random true/false to have random direction
|
|
// /CCal/generator/scan true/false to scan in eta/phi
|
|
// Use
|
|
// /CCal/generator/minEnergy
|
|
// /CCal/generator/maxEnergy
|
|
// /CCal/generator/minPhi
|
|
// /CCal/generator/maxPhi
|
|
// /CCal/generator/minEta
|
|
// /CCal/generator/maxEta
|
|
// to set the range in energy and direction of particles shot at random.
|
|
// Use
|
|
// /CCal/generator/stepsPhi
|
|
// /CCal/generator/stepsEta
|
|
// to set number of steps in Phi and Eta for the scan
|
