Users' Executive Committee

The LCLS Users' Executive Committee (LCLS UEC) is the formal organizational unit of the LCLS Users' Organization (LCLS UO).

The LCLS UO provides an organized framework and independent vehicle for interaction between the scientists who are interested in using the Linac Coherent Light Source (the users) and LCLS/SLAC Management. The LCLS UO is broadly concerned with representing the interests of the LCLS users to SLAC management, so as to facilitate the availability and effective use of LCLS for the research community.

SSRL/LCLS Annual Users' Meeting

Each year the SLAC National Accelerator Laboratory welcomes users to the joint users' meeting of the Stanford Synchrotron Radiation Lightsource (SSRL) and the Linac Coherent Light Source (LCLS). This annual meeting is a unique opportunity to gather together the light source community in a single scientific event with talks and presentations by leading scientists, poster sessions, and parallel workshops. Learn about current/future facility capabilities and the latest user research, and discuss science with colleagues from academia, research laboratories, and industrial partners worldwide.

SSRL/LCLS Users' Meeting: 22-27 September, 2024

Visit past users' conference programs (2023, 2022, 2021, 2020, 2019, 2018, 2017, 2016, 2015, 2014) and read past summaries (2021, 2020, 2019, 2018, 2017, 2016,  2015).

LCLS Users' Organization Executive Committee

LCLS UEC members are elected by the members of the LCLS user community. The UEC communicates the needs and desires of users regarding LCLS operating policies, use of LCLS, user support, and other relevant issues of concern to those engaged in research at this facility.

Download LCLS Users' Organization Charter and By-laws

LCLS UEC members serve a three-year term, beginning and ending in October when the annual elections are held. The person elected UEC Chair is asked to serve on the committee for two additional years to facilitate continuity of LCLS UEC activities.
