Welcome to the LCLS User Resources Site

The Linac Coherent Light Source (LCLS) encourages scientists from diverse fields to submit proposals for experiments that utilize the LCLS's unique capabilities. Interested scientists are encouraged to learn more about the latest developments by contacting LCLS staff scientists and by reviewing the instrument descriptions.

Step-By-Step Instructions to Working at LCLS

LCLS Instruments and Beam Lines
Atomic, Molecular and Optical Science (AMO)
Beam Line for Soft X-ray Science (SXR)
X-ray Pump Probe (XPP)
Coherent X-ray Imaging (CXI)
X-ray Correlation Spectroscopy (XCS) The split and delay capability is still under commissioning for the XCS instrument.
Matter in Extreme Conditions (MEC)

We have demonstrated FEL operations over the energy range 480 eV to 10 keV using the fundamental with pulse energies of 1-3 mJ depending on the pulse duration. Third harmonic radiation is available up to 25 keV at about 1% of the fundamental pulse energy. The pulse length can be varied from 40 fs to 300 fs for hard X-rays, while for soft X-rays the range is extended to 500 fs. Shorter pulses, <10 fs, with a reduced number of photons per pulse can also be provided. The maximum repetition rate of the LCLS is 120 Hz.

SUBMIT NEW PROPOSALS BY 4 pm PACIFIC on Tuesday, January 15, 2013. This is the only call for regular proposals in 2013. The next opportunity to submit new proposals will be in early 2014 (due to the long shutdown anticipated ~March-October 2014 to begin LCLS II tunneling construction).

Submit protein crystal screening (PCS) proposals for the CXI instrument before 4 pm PACIFIC on Tuesday, February 12, 2013.

Instruments Included in Call for Proposals	Proposal Deadline
AMO, SXR, XPP, CXI, XCS, MEC	January 15, 2013
CXI (Protein Crystal Screening)	February 12, 2013

Proposals, safety training, user registration and user check-in are centralized to ensure prompt and efficient service to our users. A call for proposals will be solicited twice per year, and a successful proposal will be eligible to receive beam time about 9 months after being submitted.

Prior to arrival at LCLS, users are required to register as a new user or update their contact information through the User Portal. See step-by-step instructions above and links related to information for foreign users and logistics

We look forward to working with you and to highlighting your research through our website and newsletter.
