Paper Abstract

Presentation tells in detail the history of discovery of the channeling radiation phenomenon. Theoretically it was predicted in 1974. My first publication appeared in Physics Letters in 1976. Experimentally, the effect was proven at the SLAC facility in Stanford by a joint USA-USSR team headed by Professor Panovsky on the American side with my consultancy support. The team included two American and two Soviet experimental physicists. Channeling radiation is the most intensive, polarized and directed radiation in physics. It was studied at all major centers equipped with accelerators for electrons and positrons. Presently, when engineering reached the level of implementing small compact accelerators, channeling radiation phenomenon is experiencing a new stage of development, since it provides very wide possibilities for application, being the most intensive, polarized, tunable X-ray and gamma-ray source, and in the X-ray spectrum represents a series of characteristic lines. The line width is of the order of several %, the number of lines, their intensity and position depend, for a specific energy, on the crystallographic properties of the crystal plane. It is very significant that with the help of one and the same crystal, one can get a great number of various tunable characteristic lines.
