Although the growing utilization of computed tomography (CT)-based imaging has led to major advances in diagnostic capabilities, it has also resulted in higher cumulative radiation doses to patients. In order to fully exploit the benefits of high-resolution diagnostic CT scans while minimizing the risks of radiation-induced cancer, the realization of low-dose CT is crucial. Recent research has shown that the use of protons, rather than X-rays, for CT has the potential to greatly reduce the radiation dose delivered to the patient without reducing image quality. RadiaBeam Technologies, in collaboration with the Loma Linda University Medical Center and the University of Texas at Austin, is proposing the development of a proton CT scanner utilizing laser-driven ion acceleration (LDIA) techniques. The initial design of this system is presented.

Radioisotope sources are commonly used in a variety of industrial and medical applications. The US National Research Council has identified as a priority the replacement of high-activity sources with alternative technologies, due to the risk of accidents and diversion by terrorists for use in Radiological Dispersal Devices (“dirty bombs”). RadiaBeam Technologies is developing novel, compact, inexpensive linear accelerators for use in a variety of such applications as cost-effective replacements. The technology is based on the MicroLinac (originally developed at SLAC), an X-band linear accelerator powered by an inexpensive and commonly available magnetron. Prototypes are currently under construction. This paper will describe the design, engineering, fabrication and testing of these linacs at RadiaBeam. Future development plans will also be discussed.

RadiaBeam Technologies is in the process of developing bulk textured dysprosium as a potential replacement for CoFe steel as undulator poles. For cryogenic undulators that can be cooled below the ferromagnetic transition of dysprosium, textured dysprosium offers potential increase in the peak field of the undulator. Here we report on the progress of the project, including magnetization curves for the material and simulations of a short period undulator utilizing the material.
