Nowadays, modulation of the electron beam depth dose distributions in radiation therapy sessions is provided by sets of tissue equivalent plates or individually shaped thermoplastic boluses.

This study describes the concept of a method for the measurement of flux density distribution in the transverse plane of wide-aperture beams such as radiotherapeutic medical beams. Currently, various approaches are used to modulate a radiation field of photons, electrons, protons and ions. However, all of these methods require continuous monitoring of the dose and spatial parameters of the...

The Cherenkov radiation from train of electron bunches traveling along the axis of a partially dielectric loaded cylindrical waveguide is investigated theoretically. It is shown, that by special choice of the values of problem parameters, it is possible to generate quasi-coherent radiation from bunches in a train, on several waveguides modes simultaneously. A visual explanation of the obtained...

The change in temperature of single crystals in vacuum conditions, such as lithium tantalate (LiTaO3), gives an attractive possibility to generate and accelerate electron and positive ions fluxes up to 100 keV and more. Also, the generation of X-ray and neutron fluxes in this way is very productive. The conception of a pyroelectric accelerator implies a compact device, which does not require...

This work is devoted to the problem of acceleration of ions of various atoms in a liquid medium. This work is a continuation of the series of experimental studies carried out at the Institute of Applied Problems of Physics (IAPP) of the National Academy of Sciences (NAS) of the Republic of Armenia since the beginning of the 90s of the last century.

A desktop universal device for X-ray interferometric diagnostics of structural imperfections in single crystals was developed, created and tested. The proposed device can serve both for scratching the surface of the interferometer crystalline blocks and for bending them in order to generate dislocations in the interferometer blocks using our proposed technology.

Cherenkov effect is well-known phenomenon and finds a broad application in physics including beam diagnostics [1]. Corundum crystals irradiated by charged particles are often used as Cherenkov light source. Corundum radiators may significantly change their optical properties during extensive exploitation with particle beams that would influence Cherenkov light intensity. In this report we...

Particle and radiation beams are widely used for cancer therapy. In last decades neutron sources are becoming more and more popular for medical applications. One of the most advanced technique for cancer treatment is neutron-capture therapy (NCT). The main feature of this technique is using epithermal and thermal neutrons to create a powerful source of radiation in the human body and...

A pathway to a compact accelerator-based short-wavelength light source consists of scattering a high-power laser pulse off relativistic bright electron beams thereby producing frequency up-shifted photons. This inverse Compton scattering (ICS) process has formed the backbone of gamma- and X-ray-generation at several facilities. In the present paper, we investigate the onset of coherent ICS...

At high energy, the smaller inelastic nucleon-Carbon cross-section implies that diamond has a radiation hardness an order of magnitude higher than that of silicon. The production of high-quality diamond samples grown using the chemical vapor deposition technique paved the way for the use of synthetic diamonds in the fabrication of detectors for both charged particles and photons. Importantly,...
