Sector 20 Research Policy and Statement of Acknowledgments


The Sector 20 beamlines of the Advanced Photon Source are a publicly funded facility, both American and Canadian. The success and continued operation of this facility is determined entirely by the caliber of the research conducted on both its insertion device and bending magnet beamlines. The measure of that success is based on the appearance of results in the public domain: in refereed publications, conference proceedings or other published and generally available media. To this end, it is the policy of sector 20, as part of the APS community, to accept users for the purpose of conducting non-proprietary research, the results from which will be available in the literature in a reasonable time frame (within approximately 2 years). Users wishing to conduct proprietary research at sector 20 should do so through the APS General User program.


With the Canadian component rebranded to better reflect the support provided through the Canadian Light Source ([email protected]) the Pacific Northwest Consortium designation has been honorably retired. Even so, we gratefully acknowledge that the sector continues to benefit from substantial contributions by the University of Washington.


Publications are a crucial part of the success of any research program or facility. Sector 20 is no exception to that. We encourage our non-proprietary users to publish their research in a timely manner, lest it affect future beamtime allocations.


When the citation information is available, we request that users notify us (Contacts: any staff) as well as submit the citation details to the APS Publication Database so that the record of publications for both the APS as a whole, and the sector 20 beamlines can be kept as up-to-date as possible.

To properly reflect the support and funding for the CLS/XSD beamlines, the Statement of Acknowledgments in any publication should try to incorporate the following:


This research used resources of the Advanced Photon Source, an Office of Science User Facility operated for the U.S. Department of Energy (DOE) Office of Science by Argonne National Laboratory, and was supported by the U.S. DOE under Contract No. DE-AC02-06CH11357, and the Canadian Light Source and its funding partners.


Given that many journals do have space constraints, we recognize that the full acknowledgments may need to be abbreviated. A suggested abbreviated version is:


Sector 20 operations are supported by the US Department of Energy and the Canadian Light Source.
