Call for Proposals - Run 2
MeV-UED - SLAC National Accelerator Laboratory

Deadline Extended: 23:59 p.m. Pacific Daylight Time (PDT) Thursday, October 10, 2019
This call is for experiments to run from April 2020 through August 2020.

Proposals for beam time for MeV-UED, part of the Linac Coherent Light Source user facility at SLAC National Accelerator Laboratory, will be accepted via the web-based proposal system until 11:59 p.m. PST Thursday, October 10, 2019.

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 second External User experimental time ("Run 2") in early 2020. In Run 2, the MeV-UED instrument will offer only one experimental configuration; a recently upgraded gas-phase UED setup optimized to study nuclear and molecular dynamics (see Endstations and Specifications).

Please note the following important information:

(1) A Virtual MeV-UED “Town Hall” User Meeting will be held at 9:00am Pacific Daylight Time on Wednesday, September 11, 2019
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 October 10th. MeV-UED staff will inform the community about the latest capabilities and be available for Q&A. Information on how to connect will be sent separately.

(2) Experimental stations available to users:
