/**
|
|
* @brief Primary generator messenger
|
|
*
|
|
* Defines UI commands to set up the primary generator.
|
|
*
|
|
* By default particle gun is used as the primary generator. It can be
|
|
* controlled with standard UI commands (/gun/).
|
|
*
|
|
* "/HGCalTestbeam/generator/momentumSpread <VALUE>" to change constant
|
|
* particle energy to Gaussian distribution with sigma expressed in units of the
|
|
* initial energy (e.g. value 0.05 means sigma of 0.05 * E).
|
|
* By default it equals to 0 and constant energy value is used.
|
|
* "/HGCalTestbeam/generator/beamSpread <none/Gaussian/flat>" to define type of
|
|
* beam position spread. By default none is used.
|
|
* "/HGCalTestbeam/generator/beamSpreadX <SIZE>" to define size of beam spread
|
|
* along x axis. It is sigma of a Gaussian distribution, or half-width of a
|
|
* flat distribution.
|
|
* "/HGCalTestbeam/generator/beamSpreadY <SIZE>" to define size of beam spread
|
|
* along y axis. It is sigma of a Gaussian distribution, or half-width of a
|
|
* flat distribution.
|
|
* "/HGCalTestbeam/generator/beamZ0 <POSITION>" to define beam position along z
|
|
* axis. By default edge of the world volume is used.
|
|
*
|
|
* If installation was done with ROOT package (CMake was able to locate it),
|
|
* an additional option of input read from the ROOT file is enabled.
|
|
* It can be activated with "/HGCalTestbeam/generator/readInputFile true".
|
|
* "/HGCalTestbeam/generator/pathInputFile <FILE>" sets the path to the input
|
|
* file.
|
|
* "/HGCalTestbeam/generator/startFromEvent <N>" allows to start simulation from
|
|
* Nth event.
|
|
* Please note that in current implementation input from file needs to be
|
|
* executed in a non-multithreaded mode (or with 1 thread).
