Abstract
A system and method for rapid ramping of an MRI magnet. The system includes a cooling source for the magnet, a persistent current switch and a variable thermal link connecting the persistent current switch and cooling source. The thermal link provides a low thermal conductance connection from the cooling source to the persistent current switch while the magnet is ramping and a high thermal conductance connection for rapid cooling of the persistent current switch when the magnet reaches a target current corresponding to a target magnetic field. The method includes connecting a thermal link to a persistent current switch and a cooling source of the magnet, providing a low thermal conductance connection through the thermal link from the cooling source to the persistent current switch while the MRI magnet is ramping and a high thermal conductance connection when the MRI magnet has reached a target current corresponding to a target magnetic field, thereby providing a rapid cooling of the persistent current switch.
