Proposal Submission for the Fall Run (2023_3) was open May 1, 2023 - August 9, 2023.
Beam Time Requests (BTRs) submission was open until August 23, 2023.
Run Cycle begins on October 18, 2023, and ends on December 19, 2023.
Submitting a proposal is the first step to accessing the CHEXS (Center for High Energy X-ray Sciences at CHESS), MacCHESS (Macromolecular X-ray science at CHESS), and MSN-C (Materials Solutions Network at CHESS) beamlines. Please read the details below for information about the proposal process. If you need assistance with any of these steps, please reach out to the CHESS User Office at CHESSUserOffice@cornell.edu.
Proposal deadlines can be found here.
NOTE: If you have an active proposal in our BeamPASS that has already received beam time OR your beam time was not able to be scheduled in a previous run, please submit a new Beam Time Request (BTR) from your existing proposal. Please verify that your proposal has not expired in BeamPASS.
If this is your first time submitting a proposal to CHEXS or MacCHESS please visit the Prospective User Handbook.
Once your proposal has been reviewed by safety and peers, we will submit a Beam Time Request (BTR) to the beamline you have indicated in your proposal.
Available Beamlines (Beamline capabilities can be found on the CHESS Beamline Directory.)
PIPOXS beamline (ID2A) - CHEXS
FAST beamline (ID3A) - CHEXS †
QM2 beamline (ID4B) - CHEXS
HPBioSAXS and BioSAXS beamline (ID7A1) - CHEXS and MacCHESS
Rapid Access Submissions are available for BioSAXS
HPBio-MX and FlexX beamline (ID7B2) - CHEXS and MacCHESS
Rapid Access Submissions are available for FlexX
If this is your first time submitting a proposal to an MSN-C beamline, please discuss your project prior to submission by contacting:
* These beamlines are prioritized for Department of Defense researchers and their affiliates.
† The Forming and Shaping Technologies (FAST) beamline at CHEXS also services the structural materials community and has an open, peer review proposal system. Depending on demand and proposal scores, we often honor a “hutch swap” with FAST to give users full access to the suite of experiments possible across both beamlines.
For questions, please contact the CHESS User Office at CHESSUserOffice@cornell.edu.
"We are planning to welcome in-person users during this run and will continue to provide and expand remote and mail-in capabilities at our facility. Please indicate in your proposal how you plan to access your experiment (remote, in-person, mail-in, or joint venture). As always, we will update users on our current Covid-related restrictions. "
