produce()

void hcal::HcalRecProducer::produce ( framework::Event & event )

overridevirtual

Produce HcalHits and put them into the event bus using the HcalDigis as input.

This function unfolds the digi samples taken by the HGC ROC and reconstructs their energy using knowledge of how the chip operates and the position using HcalGeometry.

Simple calculation of sampling fraction: Thickness per layer: scintillator (0.2cm) + steel (0.25cm) Radiation length and nuclear interaction length: scintillator: X0 = 41.31cm, Lambda = 77.07cm https://pdg.lbl.gov/2017/AtomicNuclearProperties/HTML/polystyrene.html steel X0 = 1.757cm, Lambda = 16.77cm https://pdg.lbl.gov/2012/AtomicNuclearProperties/HTML_PAGES/026.html Prob of EM interaction (e.g. pi0): thickness/X0*100 = (0.2/41.31)/ ((0.2/41.31)

• (0.25/1.757)) ~ 3.3% Prob of Had interaction (e.g. pi+/pi-): = (0.2/77.07)/ ((0.2/77.07) + (0.25/16.77)) ~ 15% Then e.g. for neutron assuming 1/3 pi0 and 2/3 pi+/- composition: sampling fraction ~ (1/3)*3.3.% + (2/3)*15% ~ 11% energy of neutron = energy_deposited / 0.11;

  NOTE: For now, sampling fraction is not applied.

attlength_

double hcal::HcalRecProducer::attlength_

private

Strip attenuation length [m].

Definition at line 105 of file HcalRecProducer.h.

Referenced by configure(), and produce().

clock_cycle_

double hcal::HcalRecProducer::clock_cycle_

private

Length of clock cycle [ns].

Definition at line 99 of file HcalRecProducer.h.

Referenced by configure(), and getTOA().

correctionAmpl_

TGraph hcal::HcalRecProducer::correctionAmpl_

mutableprivate

Correction to the pulse's measured amplitude at the peak.

The correction is calculated by comparing the amplitude at the sample time (T) over its correct value (1.0) with the ratio between sample T and sample T+25ns.

Definition at line 116 of file HcalRecProducer.h.

Referenced by configure(), and produce().

correctionTOA_

TGraph hcal::HcalRecProducer::correctionTOA_

mutableprivate

Correction to the measured TOA relative to the peak.

This corrects for the time-walk effect where the time that the front edge of the pulse crosses the TOA threshold walks higher in time as the pulse's amplitude gets smaller. The correction is calculated by comparing the TOA measured relative to the peak (i.e. the time at which the pulse crosses the TOA threshold) with the amplitude at the sample time (T) over its correct value (1.0).
