Call for Proposals
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 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.

Please note the following important information:
(1) Virtual LCLS “Town Hall” User Meeting was held on August 16, 2019
On Friday, August 16, 2019 LCLS hosted a virtual “Town Hall” meeting to inform the user community about the latest technical developments at LCLS. This interactive webinar included a series of short talks by LCLS staff, with interactive Q&A throughout and open questions at the end of the session. The whole community was invited to participate, with members of the UEC and LCLS moderating questions to make optimal use of the meeting time. Please visit the link below for a recording of the meeting, a copy of the slides, and a written summary of questions and answers.

(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
