Description: Radio frequency (RF) technology is a key technology common to all high energy accelerators. RF sources with improved efficiency and accelerating structures with increased accelerating gradient are important for keeping the cost down for future machines. DOE-HEP seeks advances directly relevant to HEP applications, and also new concepts and capabilities that further scientific and commercial needs beyond HEPs discovery science mission.
Please note that this year the topics have been grouped by technology, rather than by the High Energy Physics frontier to which they belong, as was done in prior years.
In many cases the technology sought is closely tied to a specific machine concept which sets the specifications (and tolerances) for the technology. Applicants are strongly encouraged to review the references provided. Applications to subtopics specifically associated with a machine concept that do not closely adhere to the specifications of the machine will be returned as non-responsive.
For subtopics that are not machine-specific (typically labeled General Topics), applicants are strongly advised to understand the state-of-the-art and to clearly describe in the application what quantitative advances in the technology will result.
b: Pulsed Power Systems
Description: Thyratron Replacement for SLAC Modulators Grant applications are sought for a replacement for existing thyratron switch tubes that are used in line type modulators. The replacement must meet SLAC specification PS-235-380-00-R4 with the addition of an increase in peak reverse voltage hold of (10kV) and a MTBF of 10,000 hours with a stable recovery process. A desirable feature would be a design that allows for replacement or repair of the cathode.
c: Deflecting Cavities (aka Crab Cavities)
Description: (See also Beam Choppers and Deflectors in prior topic).
Deflecting Cavities for Project-X
Grant applications are sought for beam deflecting devices that can be used to deflect proton or ion bunches for the purpose of forming variable bunch patterns in high intensity proton accelerators. Topics of particular interest include narrowband transverse deflecting superconducting cavities capable of CW operation at a 406 or 427 MHz, and with a total deflection of ~7 MV, and room temperature deflecting cavities operating in CW mode at 243.75 MHz with the total deflection of ~1 MV.
Description: In addition to the specific subtopics listed above, the Department invites grant applications in other areas that fall within the scope of the topic description above.
