26th Accelerator Test Facility Users' Meeting

26 Mar 2024, 09:00 → 28 Mar 2024, 15:30 US/Eastern

BLDG 515 - ITD Large Conference Room (Brookhaven National Laboratory)

The schedule is still in the process of being compiled and this is not reflective of the final timeline.  

The Accelerator Test Facility (ATF) is a DOE Office of Science User Facility that provides users with high-brightness electron- and laser-beams, and ultrafast electron diffraction capabilities. The Accelerator Facilities Division at Brookhaven National Laboratory has provided a facility for users to study the properties of modern accelerators and new techniques of particle acceleration and radiation generation for over 30 years. It is the designated user facility for the Accelerator Stewardship Program.

Meeting Objectives

• The ATF Program Advisory Committee (APAC) will review the progress of the ongoing user experiments and approve new experimental proposals that are synergistic with the mission of the DOE Office of Science Accelerator Stewardship Program. They will also review the facility’s science goals and planning.
• The meeting will serve as a forum for collaboration and a platform for users to report their work to APAC and the research community.
• The current status, performance, and future plans for the ATF will be presented.

Please be advised that all sessions will be recorded.
