CCR proposed a periodic permanent magnet (PPM) focused klystron. Funding was cut substantially for the LINAC, and CCR received a change of scope to… More

High Gradient Accelerator Cavities Using Atomic Layer Deposition

Award Year / Program / Phase: 2014 / SBIR / Phase I
Agency: DOE
Principal Investigator: Robert Ives, Dr.
Award Amount: $150,000.00
Abstract:
The length of high energy accelerators is determined by the magnitude of the RF electric field that can be supported in the cavities without breakdown. The accelerator length directly impacts the size and cost. Efforts are continuing around the world to understand the physics of RF breakdown and… More

Low-Cost, High-Efficiency Triode Magnetrons for Accelerator Applications

Award Year / Program / Phase: 2014 / SBIR / Phase I
Agency: DOE
Principal Investigator: Michael Read, Dr.
Award Amount: $150,000.00
Abstract:
High efficiency, low cost RF sources are required for proton, ion, and muon accelerators. These sources must be compact and provide precise control of the output power. Currently only large, expensive klystrons can provide this performance. Calabazas Creek Research Inc. proposes to develop a triode… More

Robust RF Photocathodes

Award Year / Program / Phase: 2014 / STTR / Phase II
Agency: DOE
Research Institution: University of Maryland
Principal Investigator: Robert Ives, Dr.
Award Amount: $999,999.07

Abstract:
Existing high quantum efficiency (QE) photocathodes experience very short lifetimes, often only a few hours. Because of the fabrication expense for these cathodes, commercial use is impractical for most applications. Photocathodes with long lifetime are needed to make photoguns cost effective for… More
