Abstract
A cryogen tank in thermal and mechanical attachment with the equipment to be cooled. Direct thermal conduction between the cryogen and the equipment provides the required cooling. The tank is preferably arranged so as to lie within an existing profile of the cooled equipment, and to be relatively small as compared to known cryogen tanks.
Claims28
A substantially cylindrical former for a solenoidal magnet, in combination with a cryogen tank for containing a cryogen for cooling the former,
- the cryogen tank (30;40) being attached by its outer surface in thermal and mechanical attachment with the former,
- the former comprising an inner part (10a) of first diameter and at least one outer part (10b) of a second diameter, greater than the first diameter,
- wherein the cryogen tank is substantially toroidal or cylindrical in shape, and is coaxial with the former, the cryogen tank being substantially housed within a substantially toroidal volume, said volume being coaxial with the former, and having an outer diameter equal to the second diameter, and an inner diameter equal to the first diameter.
A method for cooling a solenoidal magnet, comprising the steps of:
- providing a number of coils (12) mounted on a substantially cylindrical former to form the solenoidal magnet, the former comprising an inner part (10a) of first diameter and at least one outer part (10b) of a second diameter greater than the first diameter;
- providing a cryogen tank (30;40) attached by its outer surface in thermal and mechanical attachment with the former, wherein the cryogen tank is substantially toroidal or cylindrical in shape, and is coaxial with the former, the cryogen tank being substantially housed within a substantially toroidal volume, said volume being coaxial with the former, and having an outer diameter equal to the second diameter, and an inner diameter equal to the first diameter;
- and
- filling the cryogen tank with a cryogen, thereby cooling the solenoidal magnet by conduction of heat from the coils, through the material of the former and the tank, to the cryogen.
