Experimental installation readiness & run plans for 2019/2020: On the second day we would like experiments to present a description of an engineering solution for how the experiment will be installed, a plan for execution and a description of the observables. Presentations should conclude with a clear definition of success for the first phase of the experiment.

Developing the science case for positrons and other upgrades: On the third day, the first goal is to clarify the science case for positrons. The second goal is to discuss ideas for new experiments and to understand the match to FACET-II capabilities. We hope through discussions to see an evolution of the experimental needs that improve chances for a positive review of potential proposals at the next Program Advisory Committee Meeting.

Assessment of plasma driven FELs: Plasma accelerators, both PWFA and LWFA, are being investigated as enabling technologies for 5th generation light sources. The large accelerating fields afford compact GeV beams and are predicted to produce beams with unprecedented brightness. On the fourth day we hope to discuss both the promise of this new technology as well as the practical challenges that must be addressed. 


Plasma accelerators are already producing beams approaching the quality needed for FELs. This session will discuss the practical challenges of transitioning these beams to User experiments and FELs. We will seek to define common challenges that need to be addressed and what details need to be reported to allow members of the FEL community to judge ore progress.
