Summary

The ROOT tree variables filled in MollerAnalysis.hh in AddData , which is called from MollerAnalysis.cc.
The values are defined all over the place!
I am trying to catalog exactly where, and decide whether they should be defined differently...

  • x, y, z
  • x0, y0, z0
  • kineE, px, py, pz
  • kineE0, px0, py0, pz0, theta0
  • kineE1, px1, py1, pz1, theta1
  • kineE2, px2, py2, pz2, theta2
  • kineE_org, theta_org
  • type, volume, event, ev_num, hit, track
  • ion, process, creator
  • diffXS, totXS, rate

List of variables

O - used for this generator
X - not used for this generator (seems to always be 0 or -1)

Variable ee ep ine Defined in... Description
x O O O Defined in tracking; value comes from hit information Positions at detector (mm)
y O O O
z O O O
x0 O O O Set in generator; value comes from hit information Positions at vertex (mm)
y0 O O O
z0 O O O
type O O O Defined in tracking; from hit information, but integer value defined in MollerDetectorSD Particle number
e- = 0
e+ = 1
p = 2
p = 3
photon = 4
all others = 5
volume O O O Defined in tracking; value comes from hit information Volume number; needs work
rate O O O Defined in generator Rate (Hz/μA), needs to be normalized to number thrown
track O O O Defined in tracking; value comes from hit information Primaries are track = 1 (also 2, in case of mollers)
event O O O Defined in tracking GetEventID() Currently the two moller tracks have the same event number
Variable ee ep ine Defined in... Description
kineE O O O Defined in tracking; value comes from hit information Momentum direction and energy (MeV) at detector
px O O O
py O O O
pz O O O
kineE0 O O O Defined in generator, MollerAnalysis.cc and MollerDetectorSD?; value comes from generator? Momentum directions at vertex?
px0 X X X
py0 X X X
pz0 X X X
theta0 X X X
kineE1 O O O Momentum directions at vertex?
px1 O O O
py1 O O O
pz1 O O O
theta1 O O O
kineE2 O O O Momentum directions at vertex?
px2 O O O
py2 O O O
pz2 O O O
theta2 O O O
Variable ee ep ine Defined in... Description
ion X O O Defined in MollerDetectorHit.hh; value comes from MollerDetectorSD - boolean?
ev_num O O O
process X X X
creator O O O
hit O O O
kineE_org O O O
theta_org O O O
diffXS X X X
totXS O O O



Notes

  1. For mollers, the number thrown is 2x the number specified; this will be changed in future versions...
  2. When secondaries are tracked, is second moller electron always track==2? Or are secondaries from first electron sometimes? Can we (should we) record secondaries from two moller electrons separately somehow?
