Folks of AMMRL,
Here's the question of the day:
We're planning to have a 200 MHz WB magnet installed in our lab here -
surely a first for an Astrophysics institute! The purchase order writers
are trying to get me to put specific goals in the statement of work to pay
the 3rd-party magnet engineer. They want the actual specifications of
(presumably) the field homogeneity and drift (anything else??) written in as
something that must be achieved by the engineer before payment.
Is this normal practice, and has anyone out there had to specify such
parameters before??
The magnet is a fairly old Oxford D15000 cryostat, so I'm not sure if it
ever achieved, or can now achieve, today's usual specs, which I've
determined to be ~ 10ppm homogeneity in a 20mm DSV without SC shims, or ~
0.1ppm with SC shims.
Any advice on dealing with this issue, or if I should use other
specifications, will be greatly appreciated.
Many Thanks,
Ross
