MA7
This new 6.8 Tesla horizontal field cryomagnet has strong stray fields due
to the size of its coils. Before it may be used on any instrument, force
tests have to be done. The specifications allow forces up to 1000 N
vertically and 500 N horizontally.
Restrictions
Provisional force measuremnents on RITA-II have shown that
the operation of MA7 on Rita-II is allowed:
- between 3.0 and 18.0 meV (a2 >= 37 deg) at a distance of 450 mm or more, up to 5 Tesla
- between 3.0 and 8.0 meV (a2 >= 56 deg) at a distance of 450 mm or more, up to 5.5 Tesla
- between 3.0 and 8.0 meV (a2 >= 56 deg) at a distance of 540 mm or more, up to 6.8 Tesla
For any other configuration force tests have to be done.
Anyway, these measurments should be confirmed when an
approriate adapter plate is avaliable.
How the distance has to be measured.
In this example the distance is around 400 mm.
