Professional experience

Работи в Химическия комбинат в Димитровград и в Металургичния завод в Перник

Евгений Леяровски е назначен за старши инженер в производствения отдел за ниски температури във Физическия институт при БАН (27 август 1959). Отделът е създаден през 1958 година и за него е доставена инсталация за течен азот от СССР и е построена сграда за лабораторията. Една година по-късно Е. Леяровски с помоща на един майстор специалист пуска инсталацията в действие (октомври 1960)

He was executive director of the Low Temperature Laboratory, constituted by Decision 20/1963, т. 9. of the Bulgarian Academy of Sciences on 5 June 1963 and Protocol 4, Point. 3 from 26 July 1963

He was assistant professor ІІ rank (1966) and І rank (1968)

Institute of Solid State Physics elected him for associate professor (20.12.1971) and full professor (1987)

He became a head of the Department on Magnetism and low temperature (1972)

He became scientific secretary in the Institute of Solid State Physics – BAS (1980–1988), deputy director (1988–1991) and President of the Scientific Council (1992–1994)

E. Leyarowski was creator (1968) and deputy director (1974 – 1978) of the International Laboratory of High Magnetic Fields and Low Temperatures in Wroclaw, Poland

Research

He proved and demonstrate an ability for liquefying helium with two turbodetanders by thermo -dynamical and gazoline-dynamical analysis. A detailed set up of a cycle and construction of a turbodetander are made. He created low-temperature high-speed turbodetander. It was implemented in cryogenic machinery for condensing and separation helium and neon mixture
