Electromagnetic calorimeter.
Simulation is handled by PndEmc. The energy deposit creates an PndEmcPoint, from those the task PndEmcHitProducer creates PndEmcHits.
Geometry is handled by the PndEmcMapper. The class PndEmcTwoCoordIndex is used to store the crystal coordinates and check for neighbors.
The standard way to create PndEmcRecoHit from detector hits (PndEmcPoint) involves the following tasks:
As an alternative, one can use PndEmcMakeDigi to create PndEmcDigis directly from PndEmcHits, bypassing the waveform generation and pulse shape analysis.
To simulate the full detector readout chain, the waveform of the detector and the following pulse shape analysis are simulated. The task PndEmcHitsToWaveform uses the pulseshape PndEmcAsicPulseshape for barrel, FwEndcap and BwEndcap and PndEmcCRRCPulseshape for the shashlyk. The task PndEmcWaveformToDigi then uses PndEmcPSAMatchedDigiFilter for the pulse shape analysis of barrel, FwEndcap and BwEndcap and PndEmcPSAParabolic for the shashlyk.
There are two ways running the waveform generation and pulse shape analysis in time-based simulation. One was implemented inside the PndEmcHitsToWaveform and PndEmcWaveformToDigi classes, the other one uses its own classes prefixed (in parts) with PndEmcFWEndcap. This does not mean that they are only for the FwEndcap, but they were developed for the FwEndcap first and can now be used for the whole EMC.
The variant using PndEmcWaveformToDigi creates the waveforms in the same way as for event-based simulation, but uses a different buffer PndEmcWaveformWriteoutBuffer. In PndEmcWaveformWriteoutBuffer::Modify() the waveforms are added in the case of pileup via the newly implemented operator PndEmcWaveform::operator+=(). As the noise is generated for the individual waveforms, the noise adds up quadratically in this case. The waveforms have to be sorted before digitisation (PndEmcWaveformSorterTask).
Pulse shape analysis is done in PndEmcWaveformToDigi, using the branch EmcSortedWaveform instead of EmcWaveform.
The variant using PndEmcFWEndcapTimebasedWaveforms uses a more modular approach with a simulator (inheriting PndEmcAbsWaveformSimulator) and modifier (inheriting PndEmcAbsWaveformModifier) to create waveforms. In case of pileup, the waveforms are first joined and afterwards the noise is added (by waveform modifier PndEmcShapingNoiseAdder). This variant also uses a custom writeout buffer (PndEmcWaveformBuffer).
Pulse shape analysis is done in PndEmcFWEndcapDigi. The digis have to be sorted by PndEmcDigiSorterTask. Due to limitations in PndEmcMakeCluster, the task PndEmcClusterRemoveDuplCrys is needed to remove double hits in one crystal for one event.
