In the wake of the departed

Eduard N. Tsyganov 12.09.1933 - 30.06.2025

The famous physicist, Doctor of Physical and Mathematical Sciences, professor, winner of the State Prize of the Russian Federation Eduard N.Tsyganov passed away.

Professor E.N.Tsyganov worked at the Laboratory of High Energy Physics from 1956 to 2006 after having graduated from Moscow State University. He went from a laboratory assistant to Deputy Director of the Laboratory for research.

Eduard Tsyganov was a talented scientist that deeply understood the physics and methodology of the experiment. As a recognized leader, he was often ready to take uncompromising steps to implement his ideas and Eduard Tsyganov's ideas were always bright and non-standard.

In 1970-1976, he was one of the first to organize and carry out, together with American physicists, a series of experiments to measure the electromagnetic radius of pions and K-mesons at accelerators in Protvino and the Fermi Laboratory in Batavia (USA).

In 1975, Eduard Tsyganov expressed a beautiful idea of the possibility of deflecting the trajectories of charged particles with curved crystals. Initially, reputable experts in crystallography and particle physics, both Russian and abroad, did not believe in the idea. To confirm his rightness, Eduard Tsyganov proposed an elegant experiment on the deviation of the trajectories of charged particles in curved crystals.

He organized a group of young scientists and engineers and within a year and a half, a cycle of experiments was carried out at the LHEP synchrophasotron. As a result, a new physical phenomenon was discovered - the deviation of charged particles using curved crystals. Nowadays, curved crystals are used to remove beams from accelerators in many laboratories around the world, including CERN, such crystals are also scheduled to be used as active collimators in the modernization of the Large Hadron Collider.

In 1996, Eduard Tsyganov was awarded the State Prize of the Russian Federation for these investigations.

Eduard Tsyganov was among the organizers of JINR's participation in the experiment at the electron-positron collider at CERN, he headed a group of LHEP employees in the DELFI collaboration.

From 1990 to 1993 Eduard Tsyganov worked as Deputy Director of the Laboratory, later - as a chief researcher.

Eduard Tsyganov was a principled and demanding supervisor of young employees. Under his supervision, more than 10 master's theses were defended. Five members of his group subsequently defended their doctoral theses.

Since 1994, Professor E.N.Tsyganov has carried out research at US research centres, where he worked on improving diagnostic techniques using tomographs.

Recently, Eduard Tsyganov has been enthusiastically engaged in the mechanism of cold nuclear fusion in the process of saturating crystals of heavy metals with deuterium atoms - another original idea to increase the yield of fusion reactions of deuterium nuclei proposed by him.

Professor E.N.Tsyganov was a member of the American Physical Society and co-author of more than 200 published scientific papers.

The bright memory of Eduard Tsyganov will forever live in the hearts of his students and colleagues.
