All Cryomagnetics' niobium-titanium magnets are wound using
multi-filamentary superconductor twisted within a copper matrix. The wire is carefully
chosen to provide maximum magnetic stability and minimum hysteresis. The coils are fully
impregnated with a special high thermal conductivity epoxy to prevent wire slippage (and
thus magnet training) from occurring. All magnets are fully quench protected not only by
means of the copper matrix of the wire, but also through the use of protective diodes.
Using diodes for quench protection instead of resistors guarantees linear charging of the
magnet and minimizes heat input into the cryostat during charge/discharge cycles. All
coils are tested to full field and quenched to insure that coil performance meets
specifications without degradation.
The standard solenoids all achieve rated magnetic field at 4.2K. In general, a 20% increase in this rated field can be achieved by operating the magnets at 2.2K, either by pumping on the liquid helium bath or through the use of a lambda plate. All 9T solenoids listed, for example, are capable of 11T at 2.2K. If operation beyond the 4.2K rated field is desired, however, it should be specified when the magnet is ordered. In general, all standard solenoids are designed to be able to achieve their 2.2K field at less than 100 amperes. All bore sizes quoted are nominal -- that is, the actual bore size is large enough to allow clear passage of a tube with an O.D. the size of the specified bore.
