Saskatoon, Sask. – The Canadian Light Source is extending an unexpected shutdown to repair a critical piece of equipment.

In order to complete the repairs, the CLS is cancelling user shifts until Nov. 16. Additionally, the CLS will not be issuing a call for proposals for new projects to be scheduled between Jan. and June 2019.

The issue began on June 27 when the facility’s electron source failed, resulting in a loss of beam in the synchrotron. Several broken components were identified in the main electron gun’s 220,000 volt power supply. After initial repairs, CLS staff members determined that the power supply’s transformer need to be replaced.

“We recognize that this is an unprecedented outage for the CLS and we are doing everything possible to solve the problem,” said CEO Rob Lamb.

The electron gun and its power supply are highly specialized components that were designed and built for the forerunner of the CLS, the Saskatchewan Accelerator Laboratory in 1978. The CLS is in the process of acquiring a replacement power supply.

The age, size, and importance of this component to our operations means that the shipping, testing, installation and conditioning of the new components will take several weeks.

The Canadian Light Source at the University of Saskatchewan is a national research facility, producing the brightest light in Canada—millions of times brighter than even the sun. One of the largest science projects in our country’s history, the CLS hosts annually more than 1,000 scientists from around the world who use our light to conduct ground-breaking health, agricultural, environmental and advanced materials research.

The Canada Foundation for Innovation, Natural Sciences and Engineering Research Council, National Research Council of Canada, Canadian Institutes of Health Research, the Government of Saskatchewan and the University of Saskatchewan fund our operations.
