14.9 Tesla is the maximum field achievable with nowadays technology for a split pair coil (which is needed for wide angle access). This limit could in principle be increased to 17.5 by means of a dysprosium insert for small samples. This option is not (yet) available at SINQ.
A rotatable sample stick has been made at PSI using a similar design at the ILL. This allows to leave the magnet in a fixed omega position and to turn the sample orientation within the magnet.
after several quenches, operation above 12.5 without lambda stage is not recommended see
Due to force limits, restrictions are defined for the use of MA15.
Instrument | Allowed Max. Field [Tesla] |
---|---|
RITA-2 | 11.5 ... 14.9, see MA15 Rita Restrictions |
TASP | 14.9, see MA15 TASP Restrictions |
EIGER | 13, see MA15 Eiger Restrictions |
ZEBRA | 14.9 for the longer distance as defined for MA15 |
