1. Reminder: Call for Proposals Open
Contact: clsuo@lightsource.ca

Canadian Light Source Inc. is again issuing a limited call for proposals for experimental beam time for the period of January 1 to June 30, 2006. Submission Deadline - Monday, October 3, 2005.

2. Users' Meeting 2005 - REGISTRATION NOW OPEN!
Contact: clsuo@lightsource.ca

Visit the meeting web site: http://www.lightsource.ca/uac/meeting2005/

Registration is now open for the 8th Annual Users' Meeting & Associated Workshops, November 18-20, 2005 at the University of Saskatchewan. This meeting, organized by the Users' Advisory Committee of the Canadian Light Source, will be a great opportunity to learn about the progress of the Canadian Light Source, present your recent synchrotron work or ideas for future work, and meet fellow users.

The following Workshops will also be held in association with the meeting:
- Building Time Resolved Experimental Programs at the Canadian Light Source
- Applications of Micro-Tomography in Science
- Pioneering Research in Plant Science Using Synchrotron Light
- Synchrotron Applications in Palaeontology and Archaeology

You are invited to submit posters about your recent or planned synchrotron work. The Canadian Institute for Synchrotron Radiation will again offer a prize for the best synchrotron related poster presented by a graduate student or post-doctoral fellow. The prize will be $1000 to support travel by the winner to attend a related conference of their choice in the coming year and present their work. Please register here: http://www.lightsource.ca/uac/meeting2005/

3. Experimental Facilities Update
Contact: tom.ellis@lightsource.ca

The rapid progress continued on all Phase I beamlines during Run 18 this month. First bending magnet light was brought to the experimental hutch on the Spectromicroscopy beamline. The monochromater works very well, and a first absorption spectrum was recorded. Shimming has started on the elliptically polarized undulator (EPU) for this beamline.

Intense light from the recently installed small gap undulator (SGU) was observed all the way down to the second optical enclosure on the Canadian Macromolecular Crystallography Facility (CMCF) beamline (ftp://transfer.lightsource.ca/XFG/CMCF/research_and_news/news.htm).

Measurements on both SGM and HXMA, with the participation of some of our users, are confirming that these beamlines are competitive with the best in the world.

Light was brought into the Mid-IR hutch for the first time and the Far-IR beamline has hosted a number of visitors using the Bruker IFS125HR ultra-high resolution spectrometer in a “lab-source” mode. Early measurements using synchrotron light in that spectrometer are very promising.

Finally, the VLS-PGM beamline is performing very well using the medium-energy grating and we now have a better understanding of the issues with the other two gratings. You can find a beamline status update, related to the Call for Proposals, at http://www.lightsource.ca/uso/beamline_status.php.

4. Storage Ring Update
Contact: les.dallin@lightsource.ca

Recent results include the installation of the small small gap undulator for the CMCF beamline in August and its testing in September. The device was operated with small gaps with no difficulties. With the chicane magnets set at their nominal values, x-rays were observed at the far end of the CMCF beamline with no beam steering required through the source.

With the exception of the Elliptically Polarizing Undulator, all Phase I insertion devices are now operational. Even so, commissioning of the Spectromicroscopy beamline has gone ahead using bend magnet radiation. Single bunch mode operation has been investigated. Single bunch currents up to 15 mA per bunch were observed with very little bunch distortion at this current. At this time it is necessary to fill 2 or 3 adjacent bunches to achieve reasonable injection rates.

Preliminary transverse coupling control has been investigated. Skew quadrupole response functions derived from closed orbit measurements were used to reduce the coupling from 1.5% to less than 1%.

Future plans include single bunch tests continuing during the next run. Single bunch operations will be discussed at a workshop at the next User's meeting. Coupling control investigations will also continue during the next run. Simulations show that several iterations of the coupling control can reduce the coupling significantly. As well, it should be possible to control the coupling locally. In this way it may be possible to reduce the coupling at a single source point while maintaining a larger average coupling and beam lifetime. High current operations (up to 200 mA) will be attempted in the next run. At this time 100 mA is routinely achieved. The beam lifetime (1/e) at 100 mA is over 10 hours.

7. Public lecture- Exploring “The Edge:” Historical Perspectives on the CLS
Contact: rob.pywell@usask.ca

Speaker: Ken Coates
Thursday, October 13, 2005, Time: 7:30 p.m.
Neatby-Timlin Theatre (Arts 241); University of Saskatchewan (UofS)

Presented by the UofS Department of Physics and Engineering Physics, UofS Department of History and the Canadian Light Source

The opening of the Canadian Light Source represents a major milestone for the University of Saskatchewan and for the scientific enterprise in Canada. The World Year of Physics and the establishment of the Canadian Light Source provide an occasion to reflect on the historical significance of this singular achievement in this year of Saskatchewan’s Centennial. The scientific and professional roots of the Canadian Light Source at the University of Saskatchewan warrant particular attention. The decision to construct the country's largest scientific instrument in Saskatoon puzzled many observers but, in the context of the history of the University and the Department of Physics and Engineering Physics and other units on campus, the selection was logical, if still controversial. There is another historical context worthy of consideration. The scientists using the Canadian Light Source are exploring on the edge of knowledge, generating new insights that will challenge our understanding of the natural world. There is much to be learned from the experience of early explorers, who like contemporary scientists, faced the formidable challenge of explaining their work and discoveries to skeptical audiences. Explorers in the past shocked humanity with geographical, biological, cultural and scientific discoveries and who alerted the world to new opportunities and challenges; it falls to synchrotron scientists to find the descriptive powers necessary to generate excitement and understanding about their discoveries and insights.

Ken Coates was Professor of History and Dean, College of Arts and Science, at the University of Saskatchewan. He is completing a book on the history of the Canadian Light Source.
