Under Slutskin's leadership, research at the LEMO resulted in water-cooled magnetrons generating continuous power up to 17 kW at 80 cm, and a magnetron tunable over a 30 percent wavelength variation (only reported much later). Research was also performed on frequency control and pulsed modulation. Work on magnetrons and their applications was also underway at the LIPT, and the LEMO supplied their products to researchers in Leningrad. The development of the L-Band (15–30 cm, 2–1 GHz) magnetron gained the attention of the Technical Department of the Red Army. The UPTI was tasked to investigate magnetrons for use in radio-location (radar) units. From this, an un-cooled magnetron was developed that generated pulsed power up to 60 kW at 60 to 65 cm.
