PAC Meeting, 9-11 October 2018
Trinity Conference Room B53-1350 (map)
Remote Connections (Zoom) available
The charge of the Program Advisory Committee (PAC) is to evaluate the merit and the feasibility of proposed experiments and review the progress of the existing R&D program at SLAC’s FACET- II National user facility. In addition, experiments that have already received beam time are evaluated concerning progress and effectiveness.
The committee is Chaired by Edda Gschwendtner and is expected to meet approximately once per year and reports to the Head of the SLAC FACET Division. The committee is supported with ad hoc consultants as necessary.
The full charge may be found here (link).
