An ion therapy system comprises a particle accelerator (1) mounted on a rotatable gantry (2). The particle accelerator includes a superconducting coil (17) which rotates about its axis as the particle accelerator rotates about the gantry axis in use to direct an output beam towards a target from different directions. The particle accelerator is rotatable through (180) degrees to move the beam through a corresponding arc. The particle accelerator includes cooling system arranged to cool the coil as the coil rotates. The superconducting coil (17) is mounted in a coil support (25). The coil is surrounded by a cryogen chamber (32) which is located radially outwardly from the coil (17) on the other side of the support (25). The cryogen chamber is in fluid communication with a cryogen recondensing unit (29) whereby vaporized cryogen may flow from the cryogen chamber (32) to the cryogen recondensing unit (29) to be recondensed in use before returning to the cryogen chamber. Thermally conductive means (40) is arranged to facilitate heat transfer from the superconducting coil (17) to the cryogen chamber (32) to vaporize cryogen contained therein in use and thereby remove heat from the coil.

A vacuum chamber (2) has walls having an inner layer (20) of a gas impermeable electrically non-conductive material and an outer layer (22) of a different electrically non-conducting material. The inner layer (20) is a polymeric film layer of Kapton® polyimide. The outer layer (22) is a composite material which includes reinforcing carbon or glass fibers bound in a matrix of epoxy resin. The vacuum chamber has end flanges for attaching it to adjacent parts of a vacuum system. The vacuum chamber is made by placing a sheet of Kapton® material around a mould and sealing its ends together. The composite material is then wound onto the inner layer in its wet form to provide the outer layer. The outer layer material is then cured to dry the epoxy resin, binding the layer to the inner layer, and the multi-layer structure removed from the mould. The vacuum chamber is particularly suitable for use in an ion implantation system in the presence of a time varying magnetic field.
A superconducting system comprises a superconducting coil (3) mounted in a support (12). The coil is surrounded by a cryogen chamber (17) which is located radially outwardly from the coil (3) on the other side of the support (12). The cryogen chamber is in fluid communication with a cryogen recondensing unit (33) whereby vaporized cryogen may flow from the cryogen chamber (17) to the cryogen recondensing unit (33) to be recondensed in use before returning to the cryogen chamber. Thermally conductive means (25) is arranged to facilitate heat -transfer from the superconducting coil (3) to the cryogen chamber (17) to vaporize cryogen contained therein in use and thereby remove heat from the coil. A thermal conduction path is therefore used to transfer heat from the coil to the cryogen in the cryogen chamber, while vaporized cryogen acts as the heat transfer medium, over the longer distance between the cryogen chamber and the recondensing unit.
