The laser-electron source of X-ray radiation (from the opening statement at workshop dedicated to the 85th anniversary of B.S. Ishkhanov in SINP MSU on October 26, 2023)

Abstract

The work, as well as the seminar at which it was reported, is devoted to the memory of the outstanding physicist-nuclear scientist, professor of Moscow State University B.S. Ishkhanov, namely his contribution to the research and development of LEXG — laser-electronic X-ray generators. Relevance and prospects of this direction are connected with «gap» between two existing types of X-ray sources: on the one hand — X-ray tubes, and on the other - electronic accelerators, storage rings and free electrons lasers. It’s about a huge difference in their bundle characteristics, cost, scale, energy consumption, etc. The history of modern projects abroad, as well as the LEXG project of MSU–Jilin University, led by Prof. B.S. Ishkhanov, are briefly presented. From the point of view of their applications, the LEXG designs can be divided into two types with different scale of the devices. The first is the replacement of serial X-ray tubes and the second is radiation medicine, nuclear technology and nuclear physics research. International conferences on LEXG have been held since 2008. The list of these is given in the Annex to the article.
