How do we change the position of the target in the subgeo configure file?

[AndrewEdmonds11]

For the tolerances study, I need to change the position of the target. Looking at the subgeo file we have:

#==================================================================================================================
#       Target
#==================================================================================================================
DEFINE: XT              100 # x Dimension of Target
DEFINE: XTB             120 # x Dimension of Target Border
DEFINE: XTBS    122 # x Dimension of Target Border Shielding
DEFINE: thT     0.1 # Thickness of Target
DEFINE: thTB    5 # Thickness of Target Border
DEFINE: thTBS   7 # Thickness of Target Border Shielding

It seems that the target region consists of:

• TargetMount
  • Target (Aluminium)
  • TargetBorder (bTgtBdWh - bTgtBdHl)
  • a box with a hole in it (Hl = hole? and Wh = whole?)
  • TargetBorderShielding (uTgtBd1 - bTgtBdWh = bTgtBdShWh - bTgtBdShHl - bTgtBdWh)

So I think, because the TargetMount is the mother volume for all these components, then I can just move the position of that one. I will check and write my progress here

Yes, only the TargetMount, needs moving.

For future reference, +y is to the right of the muon beam, -y is to the left, +x is closer to the muon beam and -x is further away.
