Description

The Canadian Light Source (CLS) currently operates a 1.9 T superconducting wiggler (SCW) that has been in service since 2005. As the risk of failure and maintenance requirements for this aging device increase, and funding for a permanent replacement remains pending, an interim solution is needed to ensure continued beamline operation. Reconfiguring a decommissioned permanent magnet undulator offers a cost-effective alternative that could minimize downtime. Several approaches to modifying the magnetic layout to enhance wiggler performance are under consideration, with the goal of reusing existing mechanical supports, permanent magnets, and vacuum chambers. Proposed modifications include reducing the gap and halving the magnetic period to achieve the desired field characteristics.

Funding Agency

The Canadian Light Source receives funding from CFI, NSERC, the University of Saskatchewan, CIHR, and the Government of Saskatchewan
