In 1928-1929, the Ukrainian Physico-Technical Institute (UPTI) was established as a Soviet research organization in Kharkov. (The Institute was later renamed Kharkiv Institute of Physics and Technology, but the original name is used herein.) 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. Upon his return from Germany, Slutskin was awarded the D.Sc. degree from KU, elevating him to the rank of professor. He was also added to the UPTI staff, heading a newly formed Laboratory of Electromagnetic Oscillations (LEMO). Here he continued with the development of magnetrons and other ultra-high-frequency (UHF) devices. 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.
