Detailed Description

A class used to define a stripped mask pattern.

This class defines a stripped pattern. It defines a periodicity and a thickness for the strips. The method TRestStrippedMask::GetRegion will return a unique id for each region in between strips.

The stripped structure is centered in (0,0) and it can be shifted using the offset defined inside TRestPatternMask. The pattern will be only delimited by the limits imposed inside TRestPatternMask.

Specific stripped metadata parameters

stripsGap: This parameter defines the strips periodicity.
stripsThickness: The thickness of the strips.
modulus: A number that defines the range of ids used to identify the different regions inside the stripped pattern. If modulus is 10, then we will only be able to identify up to 100 unique regions. If a larger amount of regions is found, it will happen that two regions will be assigned the same id.

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.

offset: A parameter to shift the pattern window mask.
rotationAngle: An angle given in radians to rotate the pattern.
maskRadius: A radius defining the limits of the circular mask.

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 TRestStrippedMask.

<TRestStrippedMask name="strongback" verboseLevel="warning">
    <parameter name="maskRadius" value="10" />
    <parameter name="offset" value="(1,2)cm" />
    <parameter name="rotationAngle" value="0.2" />
 
    <parameter name="stripsGap" value="4mm" />
    <parameter name="stripsThickness" value="0.5mm" />
</TRestStrippedMask>

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

 TRestStrippedMask mask("masks.rml", "stripped");
 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.

TRestStrippedMask mask("masks.rml", "stripped");
TCanvas *c = mask.DrawMonteCarlo(30000);
   c->Draw();
c->Print("strippedmask.png");

Constructor & Destructor Documentation

◆ TRestStrippedMask()

TRestStrippedMask::TRestStrippedMask	(	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

cfgFileName	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 TRestStrippedMask section inside the RML.

◆ GetRegion()

Int_t TRestStrippedMask::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::ApplyCommonMaskTransformation

Reimplemented from TRestPatternMask.
