Move the TM4 assymbely by 3mm radially outwards.
Whats moved:

  1. The TM4 coils
  2. Collimator 6A
  3. Collimator 6B
  4. Belly plates attached to TM4

Moving TM4 outward, is updating the x and y coordinates both by 3*cos(n*angle*pi/7) and 3*sin(n*angle*pi/7) because they are rotated by by the required angle at their location.

Collimator6A and 6B are defined as xtru solid which are shifted in x by 3mm first and then rotated about the beamline. This is why only x coordinates change in 6A and 6B and both change in TM4 coil.

The simulation results are here in docdb. (page 32 and 32 have the resulting gdml images.)
