Przemek Adrich agreed to help with new detector implementation.

---------------------------------------------------------------------------------------------

Priorities:

TPC geometry, where chamber positions are taken, (Bartosz M. and Antoni)k

implementing new detector geometry into GEANT:

MRPC: mrpc branch in SHINE (Aizat), TPC, PSD (Sergey), VD(Pawel, Ivan)

TPC Response: Reconstruction hits->clusters done by the following modules:

TPCLinearElectronDriftSG
ExBCloudPropagatorSG
TPCElectronCloudPropertiesSG
TPCResponseSimulatorSG

Brant's presentation is attached with a description of the algorithm, formulas, and parameters, for example: 

  <TPC id="VTPC2"> 
    <diffusion> 
      <xMoyalScale> 0.0230 </xMoyalScale>
      <yMoyalScale> 0.0260 </yMoyalScale>
    </diffusion>
    <lorentzAngleTangent> -0.327 </lorentzAngleTangent>
    <eventByEventT0> 0 </eventByEventT0>
    <minimalDEPerPathLengthUnit unit="keV"> 3.0 </minimalDEPerPathLengthUnit>
    <nEffectiveElectronsPerPad> 7.0 </nEffectiveElectronsPerPad>
    <nEffectiveElectronsPerWire> 5.0 </nEffectiveElectronsPerWire>
    <zeroSuppressionThreshold> 5 </zeroSuppressionThreshold>  
    <nElectronsPerPathZUnit> 35 </nElectronsPerPathZUnit>

	<x unit="cm"> 0.0240 </x>
	<y unit="cm"> 0.0360 </y>
      </resolution>
    </sector>

How do we vary these parameters for 2022+ data? At the MC Meeting on 4.12.23, we compared 2023 and 2016 data, and the short observation is:
VTPC: TSlices inc. 3->4, Npads comparable, peak MaxADC decreased x2, peak Charge decreased from 200 to ~150
MTPC: TSlices inc. 3->5, Npads comparable, peak MaxADC decreased from ~60 to ~50,  peak Charge comparable
