Compact Accelerators - 2
- William Graves (Arizona State University)
Now that superconducting RF accelerators have become the standard for discovery science facilities, it is time for them to be applied to applications in the industrial sector. As part of its REDUCE objective, the Office of Radiological Security of the National Nuclear Security Administration (NNSA) supports efforts to reduce reliance on radioisotopes through the development of alternative...
We will present a concept for a compact and efficient room temperature CW accelerator for industrial applications using a copper linac, magnetron RF and a thermionic electron source. These technologies have been proven reliable in field applications and major components can be sourced commercially. Thermionic cathodes have been shown to have very long operational lifetimes and can be replaced...
Brilliant x-ray sources including coherent free electron lasers at energies up to keVs, and incoherent monoenergetic Compton scattering sources at MeV energies and beyond have revolutionized a broad range of science from materials to nuclear signatures. Such sources require linacs at GeV to tens of GeV energies, and technologies to make such accelerators smaller have the potential to both...
Superconducting radiofrequency (SRF) accelerators are critical to scientific facilities across the world. These accelerators require large liquid helium cooling plants to maintain the extremely low temperatures necessary for their operation, resulting in high capital and operating expenses. Recently, researchers at Thomas Jefferson National Accelerator Facility (TJNAF) and General Atomics (GA)...
A compact RF linac design has been developed for an Accelerator Driven System (ADS). The linac is about 150 meters long and comprises a radio-frequency quadrupole (RFQ) and 20 superconducting RF cryomodules. Three types of half-wave cavities and two types of elliptical cavities have been designed and optimized for high performance at the frequencies of 162.5, 325 and 650 MHz. The lattice was...
