Biography[ edit ] Artem Alikhanian was born in Elizavetpol , Russian Empire, to an Armenian family of a railway engineer and homemaker. In 1912 the family moved to Aleksandropol. He worked as a waiter and a newspaper seller. In 1930, before he graduated from Leningrad State University , he became a staff-member at Leningrad Physico-Technical Institute working together with his elder brother Abraham Alikhanov.
The work of their group was devoted to the investigation of pair production and of the resultant positron spectrum. For observation of positrons, Alikhanov, his student M.
This work became a starting point for the application of radio engineering to experimental nuclear physics in the Soviet Union. Dzhelepov, Alikhanov and Alikhanian was among the pioneers observing the phenomenon of radioactive decay.
In 1942 they initiated a scientific mission on Mt. Aragats in order to search for the third proton component of cosmic rays. During the siege of Leningrad Alikhanian and some his colleagues were excused from full-time defense work in order to work on the design of a synchrocyclotron - the accelerator which was eventually constructed in Dubna in 1955. After they founded a cosmic ray station on Aragats at an altitude of 3250 m, the two brothers participated in the foundation of the Armenian Academy of Sciences and established the Yerevan Physics Institute in 1943.
Alikhanian became its Director for the next 30 years. In recognition of his scientific achievements and contribution he was awarded the "Honored Scientist of Armenian SSR" title in 1967.
For the work on wide-gap track spark chambers in 1970 A. Alikhanian together with the colleagues were awarded the Lenin Prize. Later he initiated work on x-ray transition radiation detectors.
Among with his co-workers- Alikhanov, Lev Artsimovich and others, he: This invention was considered one of the major milestones in the history of the Spark Chamber. Alikhanian was also an experienced educator. According to Wolfgang K. Wilson , Alikhanian made "very important contributions to science, in particular, in the use of transition radiation as an important tool in particle detection and identification".
Alikhanian organized visits of Arkady Raykin , Andrei Sakharov and Yelena Bonner to Armenia, hosted Joseph Brodsky at his house in Yerevan as Yuri Orlov writes, there were rumours, that Alikhanian had a web of his own spies, who helped to protect him and his colleagues from the KGB . He actively supported international cooperation of scientists. Alikhanian resigned from his position at YerPhI in 1973 and left Yerevan , after conflicts with very high level Soviet statesmen.
Wilson while working on "Meeting at a Far Meridian" novel, visited Alikhanian in Armenia and lived there for several months. His statue stands at Alikhanyan Square, Yerevan. Also there is a Memorial Cabinet-museum of Alikhanyan opened in the central building of the Yerevan Physics Institute.
