Call for Proposals
Twice a year, the CLS opens a call for proposals during which time proposals are accepted for peer-reviewed access to beamtime in the upcoming 6-month cycle. Successful proposals become active projects at the CLS and remain active for 2 years. During an open Call for Proposals, beamtime requests for active projects can also be submitted for consideration in the upcoming cycle.
The next Call for Proposals opens on January 26, 2022 and will close February 23, 2022 at 12:00pm (noon) CST. This Call is for beamtime in Cycle 36 (July - December, 2022).
|Cycle||Scheduling Period||Call Open||Call Close||PRC Meeting||Results Announced|
July - Dec, 2022
|January 26, 2022||February 23, 2022||Week of April 25, 2022||Week of May 9, 2022|
After the call for proposals has closed, submissions are grouped based on the proposed techniques and facilities and follow the appropriate review track. Each review track has a dedicated Peer Review Committee (PRC) which includes members from national and international representation knowledgeable in synchrotron-based science that perform research, manage research, or use research. The CLS Science Director appoints the Chair and members with recommendations from CLS external advisory bodies (Scientific Advisory Committee, Beamline Advisory Committee and Users' Executive Committee) and suggestions from the community at large.
General User Review Track
The Director of Science and Science Managers meet to assign each proposal for general user access to an appropriate member of the PRC. The PRC members are then responsible to review their assigned proposals and to assign each proposal to at least two additional external reviewers based on matching criteria including subject area(s), technique(s), and spectral range.

MX Review Track
Proposals for macromolecular crystallography (MX) are reviewed by at least two members of the PRC for MX.
For both the MX and the General User Review Tracks, new proposals are reviewed for technical feasibility (by CLS staff) and scientific merit (by external peer reviewers). A proposal must receive both a technical and a peer review score between 1 and 4 to be considered for allocation of beamtime. The score for scientific merit a proposal receives during this process will be used in allocating beamtime for the entire two years the project is active. Active projects will not be re-evaluated when subsequent beamtime requests are submitted.
During the review process, reviewers have an opportunity to request clarifications from the applicant if required. Technical reviewers are asked to evaluate the technical feasibility of the proposed experiment, as well as the capability of the research team, based on past publications and experience. Scientific reviewers are asked to provide an integer score for the scientific merit of the proposal.
Does the proposal describe what is to be studied and the importance of it? What hypothesis would be tested? How will the results impact the field? What is the likelihood of success?
The proposal describes highly innovative research of great importance. The proposed research will significantly advance knowledge in a specific field or scientific discipline and may have considerable societal relevance. This is a model for a well written proposal. High-risk experiments with exceptional potential can be rated in this category at the discretion of the reviewer.
The proposal describes research that is of very high quality and will likely make a significant contribution to a specific field or scientific discipline. As cutting edge research it has the potential to be published in a top-tier scientific journal.
The proposal describes research that is likely to produce publishable results in specialized but not top-tier journals.
The proposal describes research that is of limited scope and will not significantly impact a specific field or scientific discipline. Publication may or may not result from this research.
The proposed research is not well planned or is not feasible, or the proposal is so poorly written it is impossible to judge. The work as described is not likely to result in publication.
Once external reviews have been completed, the Peer Review Committee meets to discuss the results. Particular attention is paid to proposals showing a high standard deviation in scores. Once consensus has been reached, proposals will be ranked in order based on scores for the quality of science and suitability. Proposals with equal scores will be grouped together. These scores and recommendations with respect to shifts are then passed on to the Allocation Committee, chaired by the CLS Science Projects Manager, and composed of Beamline Scientists and Science Managers.
An Allocation Committee comprising the Director of Science (or delegate), Science Managers, and CLS beamline staff meets twice per year to determine which active projects will be allocated beamtime based on the scientific merit rankings from the Peer Review Committee. Projects resulting from the most recent round of peer review are evaluated along with any beamtime requests submitted for the upcoming cycle. The Allocation Committee determines the amount of beamtime to be allocated to each project. Projects with scores close to the cut-off score are closely analyzed, and scores for the quality and capability of the researcher may become a deciding factor. A representative of the UEC is invited to allocation meetings to monitor the allocation process.
For each beamline, a Memorandum of Understanding (MOU) describes the percentage of beamtime to be reserved for access groups including purchased access, beamline team members, beamline maintenance/upgrades, beamline staff experiments, and general user access. Prior to the Allocation meeting, each access group identifies how much of their allotted beamtime is required for the upcoming period. Any shifts that are not required are returned to the Director of Science to reassign at their discretion.
After beamtime allocations have been approved and users have been informed of the results for their proposals and beamtime requests, beamline staff begin scheduling the available beamtime for the upcoming cycle. This process typically involves direct communication between beamline staff and users to arrange a schedule that both maximizes available beamtime and accommodates users' individual scheduling requirements.
Given the complex nature of synchrotron facilities, when user beamtime is lost due to unforeseen circumstances, it will not automatically be rescheduled. CLS is committed to working with affected users to maintain the continuity of their experimental programs. On a user-by-user basis, discretionary time may be allocated when possible.
CLSI promotes and encourages open communication between all users of the beamlines at the CLSI facility. In the event conflicts between users, CLSI and possibly third parties arise that cannot be solved by general interventions, the following process will be followed.
Parties/individuals are encouraged to discuss any issues of concern/problems which may arise in a timely manner to resolve the problem informally. Parties/individual(s) may discuss concerns with:
- User Services Office
- Users' Executive Committee (UEC) chair
- CLSI Science Director
- CLSI Chief Executive Officer (CEO)
Any parties/individuals with unresolved concerns who wish to proceed with a formal appeal process may do so. A formal Users' Appeal Process involves:
- Parties/individual(s) will provide written communication to the CLSI Science Director and the UEC chair outlining the concerns.
- The CLSI Science Director and UEC Chair will discuss and try to resolve the conflict within four weeks from receipt of the request.
- In the event the conflict is unresolved and pending the sensitivity of the conflict:
- The conflict will be brought forward to the members of the UEC for discussion at their next regularly scheduled meeting for discussion and resolution. The CLSI Science Director may attend the meeting to participate in this discussion.
- In the event the conflict is sensitive the CLSI Science Director and the UEC chair would identify a member of the local synchrotron community, who is neutral to the conflict, to assist in the process and try to resolve the conflict within four weeks.
- The Chair of the UEC and Science Director would report the resolution back to the parties/individuals through written communication.
- Failure for a resolution would go to an adhoc committee appointed by the CLSI CEO as required.
The resolution of the conflict will be reported back to the CLSI CEO.
