Working Groups
Workshop Structure
This initial workshop will have a strongly educational purpose, bringing adjacent communities together that have had somewhat limited prior contact, and attempting to develop a common understanding of, and strategy for, addressing the primary R&D challenges inherent in making practical DLA devices. 50% of the meeting time is allocated for plenary sessions, with the balance being breakout sessions.
Given both the brevity of the workshop and the interdisciplinary character of most of the charge, participants will be encouraged to move between breakout sessions as the topics interest them. The working group leaders must be capable of leading the breakout groups towards a consensus response to the charge items.
- WG1: Accelerator Applications; Location: Yellow
Room (Building 41, Room 223)
Working Group Leaders: Ben Cowan, Rodney Yoder
The Accelerator Applications working group will focus on applying laser and photonic structure technologies to make DLA accelerators. Parameter sets for HEP, photon science, industrial and medical applications will be developed as appropriate, and requirements on accelerator structures, material properties, and laser sources identified. Discussion will include beam dynamics, radiation generating characteristics of such beams, relevant supporting technologies (e.g. particle sources, mounting and aligning methods), and simulation methods. - WG2: Laser Technology; Location: Madrone Room
(Building 48, Room 224)
Working Group Leaders: Bob Byer, Jay Dawson
The Laser Science & Technology working group will focus on present and expected performance of lasers in the near- and mid-wave IR range capable of powering laser-driven dielectric accelerators. Discussion of performance will include power efficiency, and stability. Techniques for carrier-envelope phase locking and attosecond-class synchronization of multiple laser systems will also be considered. General guidance on future cost of accelerator-compatible laser systems will be developed. - WG3: Photonics and Novel Optical Materials; Location:
Red Slate Room (Building 280C, Room 112/114)
Working Group Leaders: Minghao Qi, Peter Bermel
The Photonic Structure and Novel Optical Material working group will consider the broad range of R&D in this area as it applied to confining synchronous accelerating modes in the optical wavelength range. The role of material properties in both gradient limitations and dephasing will be considered, as will specialized structure geometries for focusing, steering, and diagnosing beam properties. Discussion will include simulation issues specific to these highly overmoded systems.
