Detailed Description

Class for the MC transport of the CBM-STS.

Author: V.Friese v.fri.nosp@m.ese@.nosp@m.gsi.d.nosp@m.e

Version: 2.0

The CbmStsMC defines the behaviour of the STS system during transport simulation. It constructs the STS transport geometry and creates objects of type CbmStsPoints.

◆ Initialize()

void CbmStsMC::Initialize ( )

virtual

Initialisation.

         The output array is created and the map from full node path
         to unique address is filled from CbmStsSetup. Then, the base
         class method FairDetector::Initialize() is called.

Check whether a volume is sensitive.

          @param(name)  Volume name
          @value        kTRUE if volume is sensitive, else kFALSE

          The decision is based on the volume name (has to contain "Sensor").

◆ ProcessHits()

Bool_t CbmStsMC::ProcessHits ( FairVolume * vol = 0 )

virtual

Action for a track step in a sensitive node of the STS.

          @param vol  Pointer to the active volume
          @return kTRUE

          The track status is registered when entering or exiting. For all
          steps, the energy loss is accumulated. When the track exits the
          sensitive node (sensor), a CbmStsPoint is created (see CreatePoint()),
          if the total energy loss in the sensor is non-vanishing (e.g., no
          neutral tracks are registered).
          Abstract from FairDetector.

Definition at line 138 of file CbmStsMC.cxx.

References CbmStack::AddPoint(), CreatePoint(), fEloss, fProcessNeutrals, fStatusIn, fStatusOut, kSts, CbmStsTrackStatus::Reset(), and SetStatus().

◆ ProcessNeutrals()

void CbmStsMC::ProcessNeutrals ( Bool_t choice = kTRUE )

inline

Create StsPoints also for neutral particles.

Parameters

choice If kTRUE, StsPoints are created also for neutrals

By default, StsPoints are only created if there is non-vanishing energy loss for the particle in the detector. Neutral particles do normally not deposit energy, such that no StsPoints are created. For some applications however, e.g. for the calculation of the radiation dose, the neutron flux is required. For such cases, the creation of StsPoints for neutrals can be activated by this method.

virtual void CbmStsMC::Register ( )

inlinevirtual
