TRestRingsMask Class Reference

Detailed Description

A class used to define a rings mask pattern.

This class defines a set of rings limited by an inner/outter radii.

The rings radii can be initialized by a set of specific metadata parameters defined inside this class.

The rings pattern is centered in (0,0) and it can be shifted using the offset defined inside TRestPatternMask. It must be noted that it is the pattern that will be shifted and not the mask.

Specific rings metadata parameters

Note
Those parameters can be used to define the generation of a periodic ring pattern. However, it is possible to define any arbitrary ring structure using the method TRestRingsMask::GenerateRings. In that case, the previous parametersr should be left undefined.

Common pattern metadata parameters

On top of the metadata class parameters, we may define common pattern parameters to induce an offset and rotation to the pattern.

Examples

Mask pattern RML definitions can be found inside the file REST_PATH/examples/masks.rml.

The following definition ilustrates a complete RML implementation of a TRestRingsMask.

<TRestRingsMask name="rings" verboseLevel="warning">
<parameter name="maskRadius" value="9cm" />
<parameter name="offset" value="(3,3)mm" />
<parameter name="ringsGap" value="12mm" />
<parameter name="ringsThickness" value="10mm" />
<parameter name="initialRadius" value="3cm" />
<parameter name="nRings" value="5" />
A class used to define a rings mask pattern.

The basic use of this class is provided by the TRestRingsMask::GetRegion method. For example:

TRestRingsMask mask("masks.rml", "rings");
Int_t id = mask.GetRegion( 12.5, 4.3 );
std::cout << "Region id is : " << id << endl;

The following figure may be generated using the TRestPatternMask::DrawMonteCarlo method.

TRestRingsMask mask("masks.rml", "rings");
mask.GenerateRings();
TCanvas *c = mask.DrawMonteCarlo(30000);
c->Draw();
c->Print("output.png");

Constructor & Destructor Documentation

◆ TRestRingsMask()

TRestRingsMask::TRestRingsMask ( const char *  cfgFileName,
std::string  name = "" 
)

Constructor loading data from a config file.

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

The default behaviour is that the config file must be specified with full path, absolute or relative.

Parameters
cfgFileNameA const char* giving the path to an RML file.
nameThe name of the specific metadata. It will be used to find the corresponding TRestRingsMask section inside the RML.

◆ GetRegion()

Int_t TRestRingsMask::GetRegion ( Double_t &  x,
Double_t &  y 
)
overridevirtual

It returns a number identifying the region where the particle with coordinates (x,y) felt in. The method returns 0 if the particle hits the pattern.

The particle will be counter-rotated to emulate the mask rotation using the method TRestPatternMask::RotateAndTranslate.

Reimplemented from TRestPatternMask.
