Abram A. Slutskin (1891–1950) was a Ukrainian scientist and professor who had a major role in shaping radio science in the Soviet Union.
He received the Kandidat Nauk (Candidate of Science – approximately equivalent to the PhD degree) from the Physics-Mathematics Department in 1916, and remained there as a docent and researcher during the turbulent times of the Russian Revolution.
The earlier work on magnetrons by Albert Hull (American), August Žáček (Czech), and Erich Habann (German) was studied and improved, resulting in devices generating oscillations with wavelengths between 300 and 40 cm.,[1][2] (It is noted that Shteinberg was the supervisor of the research unit, and, by custom, his name was added as such.)
While there, he published another important paper on magnetrons in Annalen der Physik, a highly respected and widely read German journal.
The primary staff, including Ivan V. Obreimov, the director, was transferred from the Leningrad Physico-Technical Institute (LPTI), but the UPTI shared many senior personnel with KU.
At KU, his students included Aleksandr S. Usikov, Semion Y. Braude, and Ivan D. Truten, all of whom would later make major contributions in this field at the LIPT.
Development of the pulsed, L-band transmitter was under Usikov, and Braude designed a superheterodyne receiver using a low-power magnetron as the local oscillator.
The radio-location work at the LEMO was conducted in great secrecy, and other units of the UPTI objected to the lack of "freedom of scientific knowledge".
For this, the UPTI was split, most going to Alma-Ata in Kazakhstan, and the LEMO to Bukhar in Uzbekistan, separated by 1,500 km; thus the war accomplished what the scientists had earlier failed to do.
Code-named Rubin, this system used an improved transmitter and receiver from Zenit, but had a single antenna, made possible by a device (a duplexer) personally developed by Truten.
[8] As the war closed in the summer of 1945, both the UPTI and the LEMO returned to Kharkov (changed in spelling to Kharkiv), but remained fully separate organizations.
