4. – Commissioning Update

(Contact: les.dallin@lightsource.ca)

Since August 6th we have been operating under our new "operating" licence. At this time we are routinely circulating 25 to 40 mA, around the clock, with the building occupied. Beam lifetimes are over 4 hrs. For the main part the beam has been available for the commissioning of the PGM beamline.

Monitoring of the beam position has improved and we now know the position of the beam at all the position monitors almost to the 1 micron (1x10-6 meter) level. This will enable us to keep beam motion at the beamline source points within our year 1 design goal. (That is, within 10% of the 350 x 50 micron beam size)

***************************************************************************

5.- Experimental facilities update

(Contact: emil.hallin@lightsource.ca)

Frontends: All frontends for phase I facilities are installed in the storage ring.

Insertion devices: Operation of the 185 mm planar undulator for the VLS-PGM has brought two issues to light, and these are being investigated. One is that it is suspected (consistent with the latest beamline results) that the insertion device may be high relative to the storage ring median plane. An alignment audit will be done to check this. The second issue is that shaft encoders are suffering radiation damage (to the optical transfer "pipe") much too soon, compared to what we had thought. We are trying to find a solution that would make the smallest vertical aperture be somewhere that is not upstream from sensitive shaft encoders, not to mention the permanent magnets in insertion devices.

IR Beamlines (Infrared): Delivery and installation of the non-optical components is proceeding with a few hiccups. It is hoped that optical installation can occur during the long shutdown this fall.

VLS-PGM Beamline (Variable Line Spacing- Plane Grating Monochromator): The August run was a success as specific (and readily reparable) problems were identified in the motion of the M1 and M2 mirrors. In addition, an alignment audit is needed to confirm the exact positions of some optical components relative to the source (see comment in the insertion devices section above). Using all three gratings, flux that is within a factor of about 3 (at worst) from the modeled values has been achieved, demonstrating that the optical scheme of this beamline has been successfully implemented. Once the irritants associated with a vendor's design "features" are fixed, the beamline will also be easy to tune!

SGM Beamline (Spherical Grating Monochromator): Two components are not yet installed: the water cooled entrance slit and the water cooled gratings. The entrance slit has been delayed by a long string of vendor engineering problems. Last e-news the vendor was expected to deliver the slit in July for the August run. Now it is expected in September in time for the October run.

SM Beamline (Spectromicroscopy): It is expected that the beamline (minus its endstations, a jaw assembly and a slit assembly) will be installed on the floor by the end of this month. Most of the optical components on this beamline have been thoroughly tested using control software that will be part of the final beamline control system, and are ready for installation. The testing has identified that a jaw assembly and a slit assembly are unacceptable and they have been returned to the vendor.

CMCF Beamline 1 (Canadian Macromolecular Crystallography Facility): All components are in house and many have been tested in-situ. The detector support assembly will be available in September, and the endstation will be completely instrumented by about the end of October. First light to the endstation is anticipated in the November/December running period.

HXMA Beamline (Hard X-ray Microanalysis): The main optical components are either here already or arriving soon, with the monochromator already here. The optical hutch will be available for occupancy by the end of Sept/04, and complete utility services for all the hutches will be completed in mid Oct/04. Monochromator installation and on-site tests will be completed in early Oct/04. Installation of other optical components will be started in Nov./04. This beamline is still on schedule for complete installation before the end of this year, with the exception of the expected delay for delivery of the superconducting wiggler by about one month.

8.- “Public Science in Liberal Democracy: The Challenge to Science and Democracy”, Oct. 14-16, 2004

Please be advised of an upcoming international conference at the University of Saskatchewan, Saskatoon, entitled "Public Science in Liberal Democracy: The Challenge to Science and Democracy." The conference will include world experts on governing science and public policy. You might want to come and participate in this innovative event and be a part of our anticipated thought-provoking debate.

The list of international speakers includes:

  • Dr. Steven Shapin, Department of the History of Science, Harvard University
  • Dr. Peter Cook, Chief Executive, Cooperative Research Center for Greenhouse Gas Technologies (CO2CRC), Canberra, Australia
  • Dr. Alan McHughen, Biotechnology Specialist, University of California
  • Dr. Michael Ruse, Lucyle T. Werkmeister Professor of Philosophy, Florida State University

Who: The conference will include essays presented by major international scientists from academia, business and government as well as academics from several disciplines in the humanities and social sciences. We anticipate 200 participants from local and global locations will contribute to the debate about how society can make better choices about complex science and technology.

What: The conference will focus on three key questions:
1. Can science retain independence and objectivity in the face of demands to meet commercial and public policy objectives? 2. In what ways is scientific discourse privileged in the formation of public policy? 3. How can scientific knowledge and scientific methodology be made compatible with the interdisciplinary and integration required in public policy discourse and formation?
