APPARATUS AND METHOD FOR INSTALLING COOLING TUBES ON A COOLED FORMER
A superconducting magnet structure has a thermally conductive former with a former body having a former surface and a channel in said former surface that is open at said former surface, a thermally conductive tube disposed in the channel and configured to receive a circulating coolant therethrough, and the former body has at least one deformable retaining element integrally formed as a part of said former body and projecting from said surface of the former body next to the channel and being deformed over said tube in the channel to cover the tube in said channel and retain the tube in the channel.
