Charging analysis

Module type name (to be used for the module commands): charging

Description

The charging analysis module computes the total charge balance passing through user defined boundaries. If a particle is passing through the surface in the direction specified by the user, the charge of the particle is added, otherwise it is subtracted.

Script example:

/gras/analysis/charging/addModule chargingDetector
/gras/analysis/charging/chargingDetector/addVolumeInterface Hall Detector

Available Units

The module accepts as units all the G4 units under the “Electric charge” category. Additional GRAS units that can be used are:

  • e

Specific Module commands

The Module doesn’t have any specific commands.
