LCLS MeV-UED Run 6 Call for Proposals

LCLS is pleased to announce the proposal call for MeV-UED’s sixth external user experimental run, scheduled to begin in October 2025. In “Run 6”, LCLS MeV-UED will offer two specialized chambers for chemical science experiments. The first chamber is designed for gas-phase experiments, while the second chamber allows experiments using liquid-sheet jets. Both chambers offer a broad range of optical pumps at their interaction points.

Since 2014, the SLAC UED instrument has been developing robust methods in the pursuit of time-resolved measurements to control and understand structural dynamics and chemical dynamics in a variety of material and chemical systems.  Run 6 will leverage these successes and continue system-level improvements in machine performance and reliability.
