A scanning control system of the ion beam of MeV energies has been developed for the nuclear scanning microprobe and proton-beam writing channel as a part of accelerator-analytical complex based on the Sokol electrostatic accelerator of the Institute of A... see more

The design of a Horn-RADANT lens with electronic beam scanning for the Ka frequency band is presented. The prototype of the antenna consists of a 2bit Radant lens installed on the aperture of an E-sectorial horn antenna. A pair of grids, with rectangular ... see more

In this paper, an indoor localization system using light emitting diodes (LEDs) is presented. Location of an object is determined by scanning two LEDs at pre-defined angles which are modulated at different frequencies. During scanning process, for each LE... see more

In order to realize rapid THz detecting and imaging, a line beam scanning-based ultra-fast THz imaging platform is designed combining simple optical components and lightweight mechanical system. The designed THz imaging platform has the resolution of 12 m... see more

A numerical particle simulation code package to estimate the irradiation distribution of an electron beam machine is presented. Particle-to-particle interactions are calculated using particle-in-cell method, while the equation of motion is solved using Bo... see more

A dual-frequency and radiation pattern reconfigurable microstrip patch antenna for detecting a stationary as well as a non-stationary target is described. Six angular patches, that collectively form a circular shape, are used. All the six patches radiate ... see more

A mini-ridge filter is often used to widen the Bragg peak in the longitudinal direction at low energies but not high energies. To facilitate the clinical use of a mini-ridge filter, we performed a planning study for the feasibility of a mini-ridge filter ... see more

We present a technique for measurement of current density distribution in cross-section of ion beam of electrostatic accelerator. The technique is based on the detection of ion induced X-ray emission from special target that may be moved across the beam i... see more

Objective: to explain the meaning and to illustrate technical artifacts (aliasing as well as the ring artifact) and beam hardening (metal artifact) that can be present in the dentomaxillofacial cone beam computed tomography (CBCT), and to check the access... see more
