First Magnetic Tests of a Superconducting Damping Wiggler for the CLIC Damping Rings

Each of the proposed CLIC electron and positron damping rings will be equipped with 76 wigglers. The length of each wiggler is 2 m, the period length lambda 40 to 50 mm, and the beam-stay-clear gap 13 mm. The minimum required mid-plane field B0 is 2.5 T, that can only be obtained with superconductin...

description Each of the proposed CLIC electron and positron damping rings will be equipped with 76 wigglers. The length of each wiggler is 2 m, the period length lambda 40 to 50 mm, and the beam-stay-clear gap 13 mm. The minimum required mid-plane field B0 is 2.5 T, that can only be obtained with superconducting technologies. In order to demonstrate the feasibility of such a wiggler, a short model with a period length of 40mm was built and successfully tested at CERN. The measured mid-plane field was 2 T at 4.2K and 2.5 T at 1.9 K in the center of a 16mm gap. The currents were 730 and 910 A, respectively. To fulfill the field specification for the CLIC damping rings at 4.2 K it is planned to replace the Nb-Ti wire with a Nb$_{3}$Sn wire.
