Call for Proposals - Run 22
Linac Coherent Light Source - SLAC National Accelerator Laboratory

Deadline: 4:00 p.m. Pacific Standard Time (PST) 28 February 2023
This call is for experiments to run from August 2023 through March 2024


We are pleased to announce the call for LCLS Proposals for Run 22. This Run offers the first user experiments using the beam from the new LCLS-II superconducting high repetition rate accelerator and the initial set of new soft x-ray instruments. It also offers a continuation of the existing hard X-ray instruments, but now with dedicated use of the LCLS copper linac accelerator.

LCLS encourages scientists from diverse fields and backgrounds to propose experiments utilizing the facility’s capabilities. New users are particularly welcome.

For this Run, the superconducting accelerator is expected to be operated up to 33 kHz. Detailed performance parameters will be subject to lessons learned during commissioning over the next few months, and so proposals should be adaptable to a range of likely performance levels. The existing copper accelerator will continue to operate up to 120 Hz for the hard X-ray instruments.

User proposals are sought for two soft X-ray instruments (TMO & ChemRIXS) and all hard X-ray instruments (XPP, XCS, MFX, CXI & MEC). For the soft X-ray instruments, an Early Science program is planned with user community participation.
