	Recently, the Advanced Accelerator and Ultrafast beam Lab (AAUL) at Idaho State University (ISU), has been developing an X-band linac for the medical CyberKnife project by collaborating with Korean Atomic Energy Re- search Institute (KAERI) and Radiation Technology eXcellence (RTX) [1–3]. The medical CyberKnife is essentially an X-band linac, which is attached to a robotic arm for precise cancer treatment. The X-band linac has considerable advantages in cancer treatment over C-band or other RF linacs, partly due to its compact size and light weight. These qualities make the X-band linac easier to attach to a robotic arm, thus making it more maneuver- able. Other advantages include a higher accelerating gradient and a higher shunt impedance. Since high mobility is necessary for precise cancer treatment, the compact X-band RF linac was selected for the CyberKnife project. This paper describes detailed design processes of the X-band linac structure, which was done with 2D SUPERFISH and 3D CST MICROWAVE STUDIO (CST MWS) electromagnetic simulation programs.

	The Idaho Accelerator Center (IAC) has been operating nine low energy accelerators for THz and X-ray light sources, nuclear physics, and medical isotope generation. In November 2012, the IAC and RadiaBeam collaborated to upgrade an IAC 44 MeV L-band RF linac with a chicane bunch compressor and a THz-radiator with periodic copper gratings for the wakefield radiation. In this paper, we report our recent experimental demonstration of a high average power (~ 17 W range in the RF macropulse) sub-THz wakefield radiation from the THz radiator without using any sub-ps laser or undulator.

	The Idaho Accelerator Center (IAC) of Idaho State University has been operating a 44 MeV L-band linac for high average power THz generation, various nuclear physic related applications, medical isotope generation, and Laser Compton Scattering (LCS) based X-ray generation. As of August 2012, the IAC has been upgrading the 44 MeV linac with a new computer based EPICS accelerator control system to replace the old analog control system. So far, this upgrade includes control of two GigE CCD cameras, and several magnet power supplies with embedded IEEE controllers. However, the 44 MeV linac also has some magnet power supplies which are controlled with external RSTL controllers. This paper describes the development of the EPICS accelerator control system to control Lambda EMS and TCR magnet power supplies with these external RSTL controllers.
