Abstract

fetched live from OpenAlex

The Canadian Light Source (CLS) in Saskatoon has been under construction for the last 4 years, and will be producing a number of very intense beams of far-IR, IR, soft and hard X-rays in 2004 for use by several hundred Canadian scientists in chemistry, surface and material science, and a host of other scientific disciplines. The CLS will dramatically enhance the Canadian spectroscopic tradition that Gerhard Herzberg help create. I begin this article (from my 2002 CIC Montreal Medal lecture) with an overview of the history of SR in Canada, beginning in 1972 with the first Canadian synchrotron workshop organized at the University of Western Ontario by Bill McGowan, and attended by Dr. Herzberg. The CLS facility is then described, along with the properties of the first and second set of beamlines to be built at the CLS. These SR beams, in the IR and X-ray regions from the third generation CSL ring, will be competitive in brightness and intensity with the best beamlines in the world for most applications. Finally, some of the present Canadian SR research at foreign SR sources is described across the entire SR spectrum. All known spectroscopic and diffraction experiments are dramatically enhanced with SR; and SR opens up new areas of spectroscopy, microscopy, and spectromicroscopy that cannot be studied with any other source of radiation.Key words: synchrotron light, X-rays, infrared, spectroscopy.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
