History of Science at the Faculty

The subject of the first research on faculty research interests defined Dean Tereshchenko AI – Student academic Slutsky OO He studied the interaction of electrons with the fields in the microwave magnetron cutting. Increase the power output of the generator failed nets by introducing a space cathode – anode. Then multichamber magnetron was investigated in order to find ways to control the electronic frequency generation. In one embodiment, the magnetron frequency control generation was carried out by introducing the electron beam in the region between the bonds.
