SASKATOON — Two decades have passed since the launch of the Canadian Light Source (CLS), a national treasure celebrated for its groundbreaking research capabilities.

In a memorable broadcast, CBC’s Peter Mansbridge heralded the CLS at the University of Saskatchewan (USask) as “Field of Beams,” marking the grand promise of transforming a prairie site into a crucial scientific asset.

The Power of the CLS

The CLS operates like a super microscope, generating light millions of times brighter than the sun, powered by electrons traveling at phenomenal speeds in a massive ring. This synchrotron facility has empowered researchers to observe materials at the atomic level, delving into the intricate structures of metals, organic matter, textiles, and even human cells.

Impact and Discoveries

Bob McDonald, host of CBC’s Quirks and Quarks, aptly predicted that the discoveries made at the CLS would surpass our wildest expectations. Fast forward to today, and over 1,000 scientists from academic, governmental, and industrial sectors are utilizing the CLS to tackle pressing challenges. Their groundbreaking work includes advancements in drug delivery therapies, the pursuit of vaccines for gastric cancer, conversion of blood types to universal donors, and innovative recycling of mining waste into fertile soil.

A Historical Foundation

USask’s journey to host Canada’s only synchrotron stems from years of dedication to developing expertise in related fields. This foundation can be traced back to the establishment of a unique spectroscopy lab in the 1930s by Dr. Gerhard Herzberg, a Nobel laureate who explored molecular structures using light spectra.

Pioneering Contributions

The university has a rich history in radiation chemistry, highlighted by contributions from physicists like Ertle Harrington, who provided radon for cancer treatment, and Dr. Leon Katz, who led the acquisition of Canada's first betatron. Dr. Katz and his peers achieved significant milestones, including innovative uses of cobalt-60 radiation for cancer therapy, shaping the future of medical treatment.

Strategic Partnerships

The inception of CLS was made viable thanks to strategic partnerships and funding collaborations. The facility cost approximately $173.5 million, bolstered by contributions from local and provincial governments, USask, and endorsements from multiple other universities. This unprecedented funding model set a historical precedent for Canadian scientific projects.

Ongoing Research and Future Prospects

Research at the CLS has not only elevated USask’s status as a leader in particle physics but has also spearheaded impactful discoveries. Studies are underway to develop new materials that can assist in the safe storage of nuclear waste and create sustainable agricultural practices in regions like Nigeria and Benin.

Economic Impact and Adaptation

The CLS also plays a pivotal role in the broader economy, with estimates suggesting that every dollar invested in the facility returns twice that amount in national GDP impact. This figure underscores the value of investing in scientific innovation and research.

A Legacy of Innovation

Recently, the 60-year-old linear accelerator at the CLS was dismantled to make way for a modernized system, reflecting the need for adaptation in an ever-evolving scientific landscape. Stakeholders are actively reviewing the future requirements of synchrotron facilities in Canada, indicating an ongoing commitment to innovation.

Looking to the Future

As the CLS prepares to celebrate its 20th anniversary during the 2024/2025 academic year, it stands as a testament to the synergy of unique expertise, relentless drive, and collaborative spirit that fueled its creation. The legacy of the CLS not only enriches science but also guarantees its continued influence on the future of research and public health in Canada.
