1. CALL FOR PROPOSALS OPENS TUESDAY AUGUST 3, 2010
Contact: mailto:clsuo@lightsource.ca
The Cycle 13 Call for Proposals will open on Tuesday, August 3, for scheduling of beam time for the January-June, 2011 period. The schedule can be viewed at http://www.lightsource.ca/operations/schedule.php
***THE DEADLINE FOR PROPOSALS IS SEPTEMBER 8, 2010***
GENERAL USER PROPOSALS received for operational beamlines are reviewed for safety and technical feasibility, and then scored for scientific merit by an external review committee. Research time obtained through this competitive peer review process takes place twice per year. General User research should result in the publication of scientific results.
You have the option of submitting a NEW proposal or submitting a Beam Time Request against an Active Proposal. Allocation of shifts for July-December, 2009 will be based on the highest ranked proposals (both new and active). To view evaluation criteria used in reviewing and rating proposals see http://www.lightsource.ca/uso/proposal_writing_tips.php or to compare your score to others on the same beamline, please visit http://www.lightsource.ca/uso/results_of_call.php.
View participating Phase I and Phase II beamlines participating in the Call at http://www.lightsource.ca/uso/beamline_status.php
In addition to normal mode operations at 250 mA, four shifts are available for Single Bunch Mode and three for Coherent Synchrotron Radiation studies. These shifts must be applied for through the General User program.
For more information, please visit our website: http://www.lightsource.ca/uso/call_proposals.php

2. BMIT- ID ACCEPTING LETTERS OF INTENT
Contact: mailto:clsuo@lightsource.ca
The insertion device Biomedical Imaging and Therapy beamline (BMIT-ID 05ID-2 (SOE-1)) is now accepting Letters of Intent for the scheduling of beam time for the November, 2010-June, 2011 period. Letters of Intent will be considered starting September 8, 2010. The bending magnet biomedical imaging beamline is now fully open for proposals.
Letters of Intent provide the opportunity to perform exploratory experiments as the beamline is being commissioned. Due to the commissioning process, the quality of experiment results may not be optimum. In addition, absorption and phase contrast imaging will be available, but not diffraction enhanced imaging or K-edge subtraction. Research must be discussed with the beamline scientist prior to submitting an application.
For more information, please visit our website: http://www.lightsource.ca/experimental/intent_letter.php and http://www.lightsource.ca/experimental/bmit.php
If you have any questions or concerns, please contact our office at mailto:clsuo@lightsource.ca or 306-657-3700.

3. CMCF CANADIAN MACROMOLECULAR CRYSTALLOGRAPHY FACILITY - MAIL-IN AND BEAM TIME REQUESTS NOW AVAILABLE ONLINE.
Contact: mailto:clsuo@lightsource.ca
You can now request beam time for "Active" CMCF proposals online. Proposals which are approved for safety and technical feasibility (and ethics, if applicable) and which receive a score from the peer review committee between 1 and 4, will be considered ACTIVE and remain active for 2 years (four cycles). Active proposals are not re-evaluated and may request shifts as required throughout the two year timeframe.
Options for shift requests include:
Mail-In requests - data collection performed by the beamline staff on behalf of the research team. Up to three shifts per week (a total of 24 hours) are available for "Mail-In" requests. Requests are handled on a first-come, first-served basis. If simultaneous requests occur, priority shall be given to the highest peer-reviewed scoring proposal.
Beam Time Requests - data collection performed by the research team coming to CLS. All requests must be received a minimum of two weeks prior to the start of the intended beam time and no greater than six months in advance.
For additional details please see http://www.lightsource.ca/uso/macromolecular_crystallography.php

4. STONES, BONES AND PHOTONS, SASKATOON, OCTOBER 27 - 30
Contact: mailto:matthew.dalzell@lightsource.ca
The Canadian Light Source is organizing a half-day workshop on Saturday, October 30 in conjunction with the 38th annual meeting of the Canadian Association for Physical Anthropology in Saskatoon October 27-30. Entitled "Stones, Bones and Photons: Synchrotron Applications in Physical Anthropology, Archaeology, Palaeontology and Preservation Studies," the session aims to provide current and curious potential synchrotron users the opportunity to discuss the application of synchrotron techniques to physical anthropology, palaeontology and the preservation of art and artifacts.
Current synchrotron users, as well as those interested in using synchrotron techniques in their research, are encouraged to submit an abstract at the conference website (http://www.medicine.usask.ca/che/capa-conference) or contact Matt Dalzell.
For more information on the workshop, visit http://www.lightsource.ca/stones&bones

6. RESEARCH HIGHLIGHT: Resolving the Chemical Variation of Phosphates in Thin ZDDP Tribofilms by X-ray Photoelectron Spectroscopy Using Synchrotron Radiation: Evidence for Ultraphosphates and Organic Phosphates
Contact: mailto:jigang.zhou@lightsource.ca
X-ray photoelectron spectroscopy using a synchrotron source (SR-XPS) with variable photon energy has been used to non-destructively elucidate the variations in surface chemistry from ~5 nm to ~10 nm into the tribofilm derived from zinc dialkyldithiophosphate (ZDDP) in a mineral oil under boundary lubrication conditions. The elemental ratio of P/Zn and ''bridging'' oxygen (BO)/''nonbridging'' oxygen (NBO) decrease as a function of distance from the top surface of the film, suggesting a decrease of the polyphosphate chain-length into the film, as shown in many recent XPS and XANES studies. More importantly, the measured P/Zn ratio of ~3, the BO/NBO ratios of [0.5, the P 2p spectra, and the absence of other balancing cations such as iron, show the first strong evidence for an ultrapolyphosphate (such as ZnP4O11), organophosphates along with other Zn polyphosphates. The existence of ultraphosphates and/or organophosphates in this film appears to be the long-awaited answer to the apparent deficiency of cations in these antiwear films.

Resolving the Chemical Variation of Phosphates in Thin ZDDP Tribofilms by X-ray Photoelectron Spectroscopy Using Synchrotron Radiation: Evidence for Ultraphosphates and Organic Phosphates.

11. PROPOSAL AND EXPERIMENTAL PERMIT ENHANCEMENTS
Contact: mailto:clsuo@lightsource.ca
CLS has implemented changes to two main areas of our web interface to assist our users. Research team members now have the ability to add a delegate to the research team so that if the spokesperson is not available to make requests/permit amendments, the delegate may perform the tasks and take on the responsibilities of the experiment. All team members will be able to view activity related to the visit such as the proposal, permit and schedule.
Permit amendments will soon have the ability to update the materials section by adding/deleting or indicating which materials are being brought to CLS.
See details on how to create and manage your proposal at http://www.lightsource.ca/uso/web_portal.php
