Abstract

The Superconducting Magnet Group, at Lawrence Berkeley National Laboratory (LBNL), has been developing a canted cosine-theta (CCT) superconducting dipole coil as well as the coil´s supporting magnet structure. This contribution reports on the progress in the development of the coil´s winding mandrel and its fabrication options. A comprehensive study of the coil´s Lorentz forces was performed to validate the winding mandrel´s “stress interception” attributes. The design of the external structure and the application of the “Bladder & Key” technology is also discussed. Additionally, the application of these studies to a curved ion-therapy CCT dipole magnet is reported.
