Hi Bill,
I wouldn't risk the chance of wrenching the magnets inside the dewars. If
they insist, make them get an insurance policy based on achieving lineshape
before and after the move. Point out the alternative cost of new magnets,
and they should go along. Convincing the underwriter might not be so easy!
Of course, another alternative is to make them pay to have MRR
discharge/recharge the magnets before and after the move.
MRR is a likely source for a HAL Diff. box after Varian runs out. If you
upgrade, be sure to sell your old consoles to MRR so they can keep the
little guys running!!
Good luck,
Jerry
