CORED RUTHERFORD CABLES FOR THE GSI FAST RAMPING SYNCHROTRON.

PDF Version Also Available for Download.

Description

The new heavy ion synchrotron facility proposed by GSI will have two superconducting magnet rings in the same tunnel, with rigidities of 200T-m and 100T.m. Fast ramp times are needed, which can cause significant problems for the magnets, particularly in the areas of s c loss and field distortion. This paper discusses the 200T.m ring, which will use Cos0 magnets based on the RHIC dipole design. We discuss the reasons for choosing Rutherford cable with a resistive core and report loss measurements carried out on cable samples. These measurements are compared with theoretical calculations using measured values of inter-strand resistance. ... continued below

Description

The new heavy ion synchrotron facility proposed by GSI will have two superconducting magnet rings in the same tunnel, with rigidities of 200T-m and 100T.m. Fast ramp times are needed, which can cause significant problems for the magnets, particularly in the areas of s c loss and field distortion. This paper discusses the 200T.m ring, which will use Cos0 magnets based on the RHIC dipole design. We discuss the reasons for choosing Rutherford cable with a resistive core and report loss measurements carried out on cable samples. These measurements are compared with theoretical calculations using measured values of inter-strand resistance. Reasonably good agreement is found, but there are indications of non-uniformity in the adjacent resistance R,. Using these measured parameters, losses and temperature rise are calculated for a RHIC dipole in the operating cycle of the accelerator. A novel insulation scheme designed to promote efficient cooling is described.
