Funding: This work was supported by the U.S. Department of Energy (award No. DE-SC-FOA-0007702) Design features and some past experimental results are presented for a sub-THz wave source employing the Advanced Photon Source's RF thermionic electron gun. The setup includes a compact alpha-magnet, four quadrupoles, a novel radiator, a THz transport line, and THz diagnostics. The radiator is composed of a dielectric-free, planar, over-sized structure with gratings. The gratings are integrated into a combined horn antenna and ~90° permanent bending magnet. The magnetic lattice enables operation in different modes, including conversion to a flat beam for efficient interaction with the radiating structure. The experiment described demonstrated the generation of narrow bandwidth THz radiation from a compact, laser and undulator-free, table-top system. This concept could be scaled to create a THz-sub-THz source capable of operating in long-pulse, multi-bunch, and CW modes. Additionally, the system can be used to remove unwanted time-dependent energy variations in longitudinally compressed electron bunches or for various time-dependent beam diagnostics. Plans for future experiments and upgrades are also discussed. |

| TUPOY010 | 6/9 MeV S-band Standing Wave Accelerating Structure for Container X-ray Inspection System at RTX | 1924 |
|

| Recently, there is a need of X-ray inspection system around the world to combat terrorism, drug and weapons smuggling, illegal immigration, and trade fraud. A compact standing wave (SW) linear accelerator (linac) for container X-ray inspection system has been produced at Radiation Technology eXcellence (RTX) to meet this growing need. The RF accelerating structure uses standing wave side-coupled structure fed by a 5 MW e2v magnetron with frequency of 2856 MHz. The electrons are accelerated from DC gun with energy of 25 keV to the final energy of 6 or 9 MeV at the X-ray target and generate X-ray with the dose rate of 8 Gy/min at 1 m after X-ray target. In this paper, we describe the design and optimization of side-coupled RF structure operating at π/2 mode. The beam dynamic of particle along the RF structure is also included in this paper by using ASTRA code. | ||

| WEPMR052 | Development of EPICS Control System for ODA Magnet Power Supplies and GigE CCD Camera | 2392 |

| The Radiation Equipment Research Division of the Korea Atomic Energy Research Institute has been op-erating a 10 MeV RF electron linear accelerator, which is used for electron beam irradiation. The beam power and energy of the RF electron linear accelerator are 10 kW and 10 MeV. The accelerator is composed of an electron gun, an S-band (= 2856 MHz) accelerating structure, a klystron, electromagnetic solenoids, a scanning electromagnet, an RF driver, a modulator, and a chiller. The linac components have deteriorated due to a long operation time of 9 years. In this paper, we described Experimental Physics and Industrial Control System (EPICS) to control ODA magnet power sup-plies for solenoids and steering magnets of the 10 MeV electron beam irradiation accelerator. | ||
