Patent number: 8907594Abstract: 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.Type: GrantFiled: February 9, 2010Date of Patent: December 9, 2014Assignee: Tesla Engineering Ltd.Inventors: Michael Colin Begg, Frederick Thomas Goldie

Publication number: 20090291035Abstract: 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 KaptonĀ® 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 KaptonĀ® 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.Type: ApplicationFiled: May 23, 2008Publication date: November 26, 2009Inventors: Michael Colin Begg, James Cumming Ramage

Publication number: 20090038318Abstract: 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. The thermally conductive means (25) is highly thermally conductive at cryogenic temperatures. In use, the highly thermally conductive means (25) facilitates transfer of heat from the coil (3) to the interior of the cryogen chamber (17) to vaporize cryogen located therein.Type: ApplicationFiled: November 9, 2007Publication date: February 12, 2009Applicant: Telsa Engineering Ltd.Inventors: Michael Colin Begg, Frederick Thomas David Goldie

Patent number: 7145337Abstract: Apparatus (10) for use in MRIS includes a coil arrangement having drive coils (20), shield coils (30) and a power supply unit (PSU) (40). The drive coils (20) and the shield coils (30) are connected in series to the PSU (40) to form a circuit. The shield coils (30) are connected between a first and second length of the drive coils (20) so as to straddle a virtual earth of the circuit. This is advantageous in minimising potential differences within the shield coil (30) assembly and thereby in minimising partial discharge therewithin. Partial discharge between adjacent parts of the drive coils (20) is minimised by spatially arranging those coils (20) such that parts thereof that are at a high electrical potential are spatially adjacent parts thereof that are simultaneously at a potential of the same polarity of at a low electrical potential of either polarity.Type: GrantFiled: June 9, 2003Date of Patent: December 5, 2006Assignee: Tesla Engineering LimitedInventors: Frederick Thomas Goldie, Michael Colin Begg

Patent number: 5868832Abstract: Magnetic field generating apparatus comprises a pair of axially spaced coils which are so arranged that when energized, they produce a magnetic field which has a zero axial field or substantially zero axial field at an axial position midway between the coils. The annular space between the coils is filled with a material such as steel or steel with a layer of material magnetized in the radial direction, which enhances the radial field strength generated by the coils. The apparatus as application in the growth of single crystals of semiconductor material.Type: GrantFiled: March 31, 1997Date of Patent: February 9, 1999Assignee: Tesla Engineering LimitedInventor: Michael Colin Begg
