The Canadian Light Source synchrotron in Saskatoon has been shut down after a cooling system went on the fritz.

The state-of-the-art particle accelerator is expected to be up and running again by the end of this month.

However, several weeks of scheduled research has been lost. Officials hope to reschedule the work for next year.

The synchrotron uses beams of intense light to probe the structure of matter. It’s the only one of its kind in Canada and is used by researchers from across the nation and 20 other countries.
