Detailed Description

Base algorithm for digitizers of the Monte Carlo hits of silicon detector based on a purely geometric criterion.

This algorithm assigns the energy released by single particles traversing a wafer of the silicon detector to the strip nearest to the entrance point in the silicon. The criterion is purely geometric and does not take into account important effects such as charge drift in the silicon, charge sharing between adjacent strips, electronic noise, GeV->ADC conversion etc.

NOTE: this algorithm cannot be used directly in analysis job; use #StkGeometricDigitizerAlgo for STK and #ScdGeometricDigitizerAlgo for SCD.

Constructor & Destructor Documentation

Constructor.

Parameters

name	The name of the algorithm.

Member Function Documentation

_CreateGeoParams()

SiliconDetectorGeoParams Herd::SiliconDetectorGeometricDigitizerAlgo::_CreateGeoParams ( const SiliconDetectorGeoParams &  origGeoParams )

private

Creates the geometry parameter objects for the digitized detector.

Starting from the original geometry parameters this method computes the digitized parameters using the digitization parameters stored in private members.

Parameters

origGeoParams

the original geometry parameters.

Returns

The geometry parameters of the digitized detectors.

Exceptions

std::runtime_error

if the relative position of the first strip on the wafer is less than 0 (i.e. strip outside the wafer).

_Digitize()

void Herd::SiliconDetectorGeometricDigitizerAlgo::_Digitize ( const SiliconDetectorParticleHitsColl &  particleHitsColl, const SiliconDetectorHitsColl &  hitsColl, SiliconDetectorHitsColl &  digHitsColl  )

private

Digitizes the silicon hits.

This function digitizes the hits of the silicon detector. It fills the collection passed as the digHitsColl argument with the digitized hits.

Parameters

digGeoParamsColl	The geometry parameters of the digitized detector.
particleHitsColl	The collection of particle hits.
hitsColl	The collection of hits.
digHitsColl	The collection of digitized hits.

FreeObjects()

std::vector< std::string > Herd::SiliconDetectorGeometricDigitizerAlgo::FreeObjects ( const std::vector< std::string > &  objs, Memory::Status  memStatus  )

override

Free the memory of unneeded objects.

Currently this method frees the memory of the digitized hits if memStatus is EXHAUSTED.

Parameters

objs	The list of objects to be freed.
memStatus	The current memory occupation status.

Returns

a list of freed objects.

Initialize()

bool Herd::SiliconDetectorGeometricDigitizerAlgo::Initialize ( )

override

Initialization of the algorithm.

Returns

true if the initialization procedure is successful.

Process()

bool Herd::SiliconDetectorGeometricDigitizerAlgo::Process ( )

override

Process a single event.

Returns

If event processing is successful.
