Detailed Description

A pure analysis process to extract information from a TRestGeant4Event.

The TRestGeant4AnalysisProcess allows to extract valuable information from a TRestGeant4Event which contains the information of energy deposits from a Geant4 MonteCarlo simulation. TRestGeant4Event stores hits which include the physical process and geometry volume id where the interaction took place. This process accesses the Geant4 event data and metadata information and it will add the observables defined by the user to the analysisTree.

Observables

This process includes generic observables by using a common pattern inside the observable name. These observables require to be completed with the name of a volume used in the GDML geometry, or the name of a particle following Geant4 conventions.

The following list describes the generic observables that can be used in this analysis process.

VolumeEDep: This observable will register the total energy deposited in a particular volume of the geometry. We must specify the volume name before the keyword volumeEDep.
// gasVolumeEDep will register the total energy deposited at the gas volume

<observable name="gasVolumeEDep" value="ON"

description="Energy deposited in the gas volume in keV" />

// vesselVolumeEDep will register the total energy deposited at the vessel volume

<observable name="vesselVolumeEDep" value="ON"

description="Energy deposited in the vessel volume in keV" />
MeanPos: This observable will register the mean position of the hits that have been registered in a particular volume of the geometry. We must specify the volume name before the keyword MeanPos, and after the keyword the axis we want to register.
// It will register the mean position in X at the gas volume

<observable name="gasMeanPosX" value="ON"

description="Mean hits position in the gas volume (X-axis)" />

// It will register the mean position in Y at the gas volume

<observable name="gasMeanPosY" value="ON"

description="Mean hits position in the gas volume (Y-axis)" />
TracksCounter: This observable will register the number of tracks of a given Geant4 particle found at each event. The keyword TracksCounter must be preceded by the name of the particle.
// It will register the number of neutron tracks per event

<observable name="neutronTrackCounter" value="ON"

description="Number of neutron tracks found in the event" />

// It will register the number of gamma tracks per event

<observable name="gammaTrackCounter" value="ON"

description="Number of gamma tracks found in the event" />
TracksEDep: This observable will register the total energy deposited by a given particle. The keyword TracksEDep must be preceded by the name of the particle.
// It will register the number of neutron tracks per event

<observable name="neutronTrackCounter" value="ON"

description="Energy deposited in the gas volume in keV" />

// It will register the number of neutron tracks per event

<observable name="gammaTrackCounter" value="ON"

description="Energy deposited in the gas volume in keV" />

Warning: It is important to notice that the keyword used for these observables is case sensitive!

In addition to these generic observables we have also an observable to measure the total energy deposited in all volumes.

// It will register the number of neutron tracks per event
<observable name="totalEdep" value="ON"
        description="Total event energy registered in keV" />

The following list provides observables that can be defined in order to add to the TRestAnalysisTree information related to the primary event, as the position, direction or energy of the the primary generated.

xOriginPrimary: x-coordinate defining where the primary event was generated.
yOriginPrimary: y-coordinate defining where the primary event was generated.
zOriginPrimary: z-coordinate defining where the primary event was generated.
xDirectionPrimary: x-component defining the momentum direction of the primary event generated.
yDirectionPrimary: y-component defining the momentum direction of the primary event generated.
zDirectionPrimary: z-component defining the momentum direction of the primary event generated.
thetaPrimary: polar angle of the primary generated particle.
phiPrimary: azimuth angle of the primary generated particle.
energyPrimary: energy of the primary event generated.
boundingSize: It stores a value with the event size calculated as the diagonal distance of a bounding box defined to contain all the hits that produced an energy deposit.

The following code illustrates the addition of a primary event observable.

<observable name="xOriginPrimary" value="ON"

description="x-coordinate of the primary event." />

There are also observables allowing to identify the events where certain physical processes took place. This will allow, for example, to select event populations where particular physics processes happened, or to determine the probability of a certain physics process to occur in our simulation.

The following list defines the physics processes observables that can be defined in this analysis process. These observables only register if the process happened or not, by associating them a value, 1 or 0.

photoelectric: It is 1 if a gamma was absorbed by a photoelectric process, 0 otherwise.
compton: It is 1 if a gamma was scattered by a compton scattering process, 0 otherwise.
bremstralung: It is 1 if gamma radiation was produced by a bremstralung process, 0 otherwise.
hadElastic: It is 1 if hadron elastic scattering took place in that event, 0 otherwise.
neutronInelastic: It is 1 if neutron inelastic scattering took place inside the event, 0 otherwise.
nCapture: It is 1 if a neutron capture process happened, 0 otherwise.
hIoni: It is 1 if a hadron ionization process took place in the event, 0 otherwise.

The following code ilustrates the addition of a physics process observable.

<observable name="bremstralung" value="ON"
    description="Its value will be 1 if the event contains a bremstralung
    physics process." />

◆ LoadConfig()

void TRestGeant4AnalysisProcess::LoadConfig	(	const std::string &	configFilename,
		const std::string &	name = `""`
	)

Function to load the configuration from an external configuration file.

If no configuration path is defined in TRestMetadata::SetConfigFilePath the path to the config file must be specified using full path, absolute or relative.

Parameters

configFilename	A const char* giving the path to an RML file.
name	The name of the specific metadata. It will be used to find the corresponding TRestGeant4AnalysisProcess section inside the RML.
