CHARGE TO WG8- NOVEL SOURCE CONCEPTS
The Novel Source Concepts WG will explore concepts and technologies that offer significant improvements in performance and/or cost over existing and proposed light sources. At the close of the workshop, we will have developed a clear description of each concept, enumerating its probable performance, cost, and the
R&D necessary to bring the concept to practice.
There will be invited presentations and contributed presentations. Previous workshops have identified laser plasma acceleration (LPA), plasma wakefield acceleration (PWFA), high harmonic generation (HHG) and inverse Compton scattering (ICS) as the leading technologies that promise to offer such significant improvements over proposed FEL-based future light sources.
We ask that the invited talks include:
1) Overview of the technology
2) Present state of the technology R&D and existing technology gaps
3) Likely performance limitations in terms of limiting brightness, limiting average power, and temporal properties (pulse duration, rep rate, coherence, spectral purity)
4) Nominal strawman design of a 500-eV source consistent with a 5 year horizon
5) Nominal strawman design of a 50-keV source consistent with a 10 year horizon
6) Discussion period with the rest of the working group members to help bring in additional material on the technology
Additional, we welcome additional contributed talks on variants of these four technologies or on other promising emerging technologies. Presentation on R&D of these topics should include answers to the following questions:
1) Overview of the technology
2) What is the likely performance in terms of limiting brightness, limiting average power, and temporal properties (pulse duration, rep rate, coherence, spectral purity)?
3) What is the present state of the R&D?
4) Nominal strawman design of a 500-eV source consistent with a 5 year horizon.
(Use the attached spreadsheet as a starting point)
5) Nominal strawman design of a 50-keV source consistent with a 10 year horizon
(Use the attached spreadsheet as a starting point) For describing a nominal design, please include: a. Rough estimate of cost and size of such a facility b. Quantified special source properties and advantages over existing and proposed light sources c. Key technical issues requiring further R&D can be identified and a roadmap sketched d. Synergy of the R&D effort with other areas (e.g. HEP, Laser Science, etc.) to be identified
