Briefly, what does this PR introduce?

The expanding beampipe should extend to the hadron endcap to ensure no overlaps are introduced by future geometry development.

What kind of change does this PR introduce?

Please check if this PR fulfills the following:

  • Tests for the changes have been added
  • Documentation has been added / updated
  • Changes have been communicated to collaborators

Does this PR introduce breaking changes? What changes might users need to make to their code?

None. Could create additional overlaps that weren't there previously, but so far have not seen any.

Does this PR change default behavior?

Yes, the beampipe is slightly longer and larger in the outgoing hadron direction.

I merely added an extra size to the envelope of the outgoing hadron beampipe. I'm not sure if any other dimensions need to be added (like the incoming lepton beampipe size), or if this is fine.

I personally don't have access to the beampipe CAD file. If someone familiar with the beampipe could double check that the envelope radius is 17.3 cm at z = 500 cm, that would be helpful.

Ran checkOverlaps.py from epic repository and no overlaps detected.
