About This PhD Project

Project Description

There are a few thousand accelerators in the world starting from small scale linear machines used for industrial or medical applications and ending with large ultra-fast particle colliders used to study the nature of creation. The operation of these accelerators would simply be impossible without a comprehensive set of diagnostics equipment. Moreover, modern machines require non-invasive techniques, i.e. when the initial fast charged particle beam parameters remain unchanged or almost unchanged.
Development of such techniques requires creative thinking and application of “smart” methods. When a fast charged particle moves in the vicinity of a substance it interacts with it via its electric field inducing radiation fields. If the substance is dielectric the radiation is known as Cherenkov Diffraction radiation (ChDR). Its parameters are very sensitive to various beam parameters. However, Cherenkov radiation is defined by a fixed emission angle.
In this project we propose to use metamaterial for generation of ChDR. Since the refractive index in metamaterials can be negative, the radiation can even be generated in backward direction. If we understand the process and establish a manufacturing technology we shall be able to manipulate by the radiation emission and develop diagnostics equipment based on a conceptually new principles.
A PhD programme will include training in metamaterial production process, theory of EM interaction, and application in accelerator science.
