Title (EN) IMPROVED SUPERCONDUCTING MAGNETS AND POWER SUPPLIES FOR SUPERCONDUCTING DEVICES
(FR) AIMANTS SUPRACONDUCTEURS AMELIORES ET SOURCES D'ALIMENTATION POUR DISPOSITIFS SUPRACONDUCTEURS
Abstract: front page image
(EN)The invention provides an apparatus for supplying power to superconducting loads including a current source, a cryogenic region (e.g., a cryogenic chamber), a first switching device in series between the current source and a superconducting load, and a second switching device in parallel with the superconducting load. The switching devices are arranged so that, when the first is closed and the second is open, recharging current is supplied to the superconducting load. The second switching device serves as a shunt. When it is closed and the first is open, current recirculates through the persistent (or partially persistent) superconducting load. The invention also provides a superconducting magnet incorporating such a power supply.
(FR)L'invention concerne un dispositif permettant d'alimenter en énergie des charges supraconductrices, comprenant une source de courant, une zone cryogénique (par exemple une chambre cryogénique), un premier dispositif de commutation en série entre la source de courant et la charge supraconductrice, et un second dispositif de commutation en parallèle avec la charge la charge supraconductrice. Les dispositifs de commutation sont arrangés de telle sorte que lorsque le premier dispositif est fermé et le second ouvert, la charge supraconductrice est alimentée en courant de recharge. Le second dispoisitif de commutation sert de shunt. Lorsque celui-ci est fermé et que le premier dispositif est ouvert, le courant circule à nouveau à travers la charge supraconductrice persistante (ou partiellement persistante). Ladite invention porte également sur un aimant supraconducteur incorporant une telle source d'alimentation.
