Konstantin Lekomtsev

Konstantin received his diploma degree in Mathematics at Moscow Engineering Physics Institute in February 2009. This background provides Konstantin with deep knowledge in mathematical physics, applied and computational mathematics and theoretical physics.

His diploma work was devoted to development of the theoretical basis of interaction between the moving charge and a chain of spherical particles. Konstantin developed the local field theory for the chain of spheres, characterized by arbitrary dielectric function, so that the results were valid for particles of any size, including nanoparticles. In this research Smith-Purcell and Diffraction radiation were investigated. These types of radiation, appearing when a charged particle moves close to a conducting target, are the most promising techniques for the applications as a non-invasive beam diagnostic.  

As a DITANET trainee at Royal Holloway University of London, Konstantin has the opportunity to apply his theoretical knowledge practically. There is also a great opportunity to accumulate practical experience, by working on CDR setup, installed in CRM line at CTF3. He is working on issues of using Coherent diffraction radiation for short bunch length diagnostics, within CTF3 – Royal Holloway’s collaboration at CERN. The CDR approach relates to non-invasive methods, relatively inexpensive and easy to use, providing information about longitudinal bunch profile. Longitudinal bunch profile reconstruction from interferogram, using Kramers–Kronig relation, is also a challenging aspect of Konstantin’s research.
