FACET-II Science Workshop 2017

Date: 17 - 20 Oct, 2017
Location: Kavli Auditorium, SLAC

FACET-II is a new user facility that will provide unique capabilities to develop advanced acceleration and coherent radiation techniques with high-energy electron and positron beams. FACET-II provides a major upgrade over current FACET capabilities and the breadth of the potential research program will make it truly unique.

A baseline design for FACET-II has been established that progressively increases capabilities in three distinct stages and is captured in the FACET-II CDR and TDR​. Stage one completes a new photoinjector at Sector 10 and re-establishes operations with high-energy high-brightness electron beams. Stage two will add a new positron damping ring system and allow user runs with high-current positron beams. Stage three will upgrade the chicane in sector 20 for simultaneous delivery of positrons and electrons to the experimental area.

By offering bunch charge ranging from pC to nC, emittance from nm to microns, electrons and positrons, single and double bunches, tailored current profiles of up to nearly 100kA and energy up to 10GeV FACET-II provides experimental capabilities unparalleled anywhere in the world. By leveraging the additional infrastructure afforded by SLAC’s laser group, the FACET laser systems provide multi-terawatt peak powers with state of the art synchronization approaching 10fs.

The FACET-II team is organizing the third of a series of workshops to discuss the scientific opportunities of this new facility, and refine the technical requirements to ensure maximum impact during early operations and into the future. The focus of the current workshop is to asses and chart the development of key technologies needed to to execute the envisioned FACET-II science program.
