This is the main function for re-simulation of the ionisation in the active gas via the PAI model.

Parameters

scaledKineticEnergy	The kinetic energy a proton would have had if it had the same Lorentz gamma factor as the particle in question.
particleCharge	Particle charge
timeOfHit	Time of hit
prex	PreStepPoint x coordinate
prey	PreStepPoint y coordinate
prez	PreStepPoint z coordinate
postx	PostStepPoint x coordinate

ClustersToDeposits()

private

Transform the ioniation clusters along the particle trajectory inside a straw to energy deposits (i.e.

potential fluctuations) reaching the front-end electronics. Effects taken into effect are:

• number of primary electrons from deposited energy
• stocastic recapture of drift electrons
• electron drift in the magnetic field (different direction end-cap/barrel). Optionally the drift time includes spread.
• Optionally signal wire propagation dealys are included. Each drift electron then gives rise to two signal: direct and reflected.

Parameters

hitID	Id of straw
clusters	ionisation clusters along particle trajectory
deposits	energy deposits on wire

  // For large Ec (actually nprimaryelectrons > 99) a much faster Gaussian shoot replaces
  // the Binomial and many exponential shoots. The Gaussian pdf has a mean of Ec and variance
  // given by sigma^2 = Ec*ionisationPotential*(2-smearingFactor)/smearingFactor. That expression

		CLHEP::HepRandomEngine *	paiRndmEngine )

Process this straw all the way from Geant4 hit to output digit.

Steps:

1. Loop over the simhits in this straw and produce a list of primary ionisation clusters.
2. Use the cluster list along with gas and wire properties, to create a list of energy deposits (i.e. potential fluctuations) reaching the frontend electronics.
3. Simulate how the FE turns the results into an output digit. This includes the shaping/amplification and subsequent discrimination as well as addition of noise.

Parameters

i	Geant4 hit collection iterator
e	last hit in collection
outdigit	The 27 bit digit (bits: 8 low + 1 high + 8 low + 1 high + 8 low + 1 high)
