Call for Proposals - Run 18
Linac Coherent Light Source - SLAC National Accelerator Laboratory

Deadline: 4:00 p.m. Pacific Daylight Time (PDT) Tuesday, September 17, 2019
This call is for experiments to run from March 2020 through December 2020.


We are pleased to announce a return to operations of the Linac Coherent Light Source facility at SLAC National Accelerator Laboratory after an extended shutdown required for the LCLS-II project and associated instrument development and upgrades. For this run, the previously existing copper accelerator (capable of up to 120 Hz) will be available with two new undulator systems and an initial set of upgraded instruments.
 
For full details of the call, please visit: https://lcls.slac.stanford.edu/proposals/run18-regular

Please note the following important information:

(1) A Virtual LCLS “Town Hall” User Meeting will be held at 8:30am Pacific Daylight Time on August 16, 2019
This webcast meeting will inform potential users about developments at LCLS before the upcoming LCLS proposal deadline on September 17, 2019. LCLS staff will inform the community about the latest capabilities and will be available for Q&A. Information on how to connect will be sent separately.

(2) New Capabilities offered for Run 18
LCLS is expected to produce X-rays in the energy range from 270 eV to 25 keV in the fundamental using two new undulators.

     - Hard X-ray Undulator (HXU): A guideline for the expected pulse energy is shown here for vertically polarized hard X-rays, with details dependent on pulse duration and other factors. For more information, please contact Sebastien Boutet (sboutet@slac.stanford.edu) or Gilliss Dyer (gilliss@slac.stanford.edu)

     - Soft X-ray Undulator (SXU): A guideline for the expected pulse energy is shown here for horizontally polarized soft X-rays, with details dependent on pulse duration and other factors. For more information, please contact Mike Minitti (minitti@slac.stanford.edu).

     - New Soft X-ray Instruments: Two new soft X-ray instruments are expected to be commissioned and available for experiments during the latter part of Run 18. These are TMO and ChemRIXS. Detailed information on each instrument can be found in the linked documents.

(3) Early Science: Immediately following technical commissioning of TMO and ChemRIXS, a period of early science on each of these instruments will be organized and led by LCLS staff and will include a limited number of expert users by invitation. If you are interested to participate and contribute to the Early Science programs on one of these instruments (or for further information) please contact the relevant instrument scientist listed below.

(4) Experimental stations available to users:

     - Time-resolved AMO (TMO) - contact pwalter@slac.stanford.edu

     - ChemRIXS - contact dakovski@slac.stanford.edu

     - X-ray Pump Probe (XPP) - contact dlzhu@slac.stanford.edu

     - X-ray Correlation Spectroscopy (XCS) - contact mchollet@slac.stanford.edu

     - Macromolecular Femtosecond Crystallography (MFX) - contact batyuk@slac.stanford.edu

     - Coherent X-ray Imaging  (CXI) - contact mliang@slac.stanford.edu

     - Matter in Extreme Conditions (MEC) - contact gilliss@slac.stanford.edu

For up-to-date information on LCLS performance, please contact the respective instrument e-mail address listed above, and see the Machine FAQ and the Machine Parameters Table, which includes a Multi-Color Pulse Mode Table.

(5) Protein Crystal Screening (PCS) Proposals: Protein Crystal Screening (PCS) proposals will be entertained by LCLS in Run 18. A separate call for PCS proposals will be issued with a planned submission deadline of October 1, 2019. For more information, please contact Mark Hunter (mhunter2@slac.stanford.edu).
