Call for Proposals - Run 3
SLAC Megaelectronvolt Ultrasfast Electron Diffraction Instrument (MeV-UED) - SLAC National Accelerator Laboratory

Deadline: 4:00 p.m. Pacific Daylight Time (PDT) 14 December 2020
This call is for experiments to run from May 2021 through September 2021

The MeV-UED instrument will accept proposals for the third external user experimental run until 4:00 p.m. PST Monday, December 14, 2020. This call is for experiments to run from May through September 2021.

Since 2014, the SLAC UED instrument has been developing robust methods in the pursuit of time-resolved measurements to control and understand molecular structural dynamics and the coupling of electronic and nuclear motions in a variety of material and chemical systems. Leveraging these successes and taking advantage of recent system-level improvements in machine reliability, we are pleased to announce MeV-UED’s third External User experimental time ("Run 3") in mid to late 2021. In Run 3, the MeV-UED instrument will offer two experimental configurations; a recently upgraded materials and single-shot setup. (see Endstations and Specifications).

Please note the following important information:
Virtual MeV-UED User Meeting will be held at 9am PST on Thursday, November 12, 2020

A webcast meeting will be held to better inform the users about the developments at MeV-UED before the upcoming MeV-UED proposal deadline on December 14th. MeV-UED staff will inform the community about the latest capabilities and be available for Q&A. Information on how to connect can be found here.

Experimental stations available to users in Run 3:

  • Solid State (Materials) & Warm Dense Matter (Single Shot) Endstation - See Endstations for details

For more detailed information on MeV-UED’s performance, please contact the instrument experimental points of contact listed below and see our instrument specifications, and our experimental layout.
