3. CVD reactor with 28 GHz gyrotron
Setup for chemical vapour deposition of diamond films on substrates up to 100 mm diameter. Microwave radiation of gyrotron with frequency 28 GHz and power up to 15 kW is used for plasma creation. Reactor operates in CW mode.
CVD method of high quality polycrystalline diamond films growth was implemented, with linear growth rate of 10-15 μm/hour, which is 5-7 times higher than the growth rate of diamond films with the same quality in conventional 2.45 GHz CVD reactors.

4. CVD reactor for diamond delta-doping
Setup for chemical vapour deposition of diamond layers on single-crystal diamond substrates. Setup implements the technology of delta-doping of diamond: creation of thin (few nanometers thick) layer of heavily boron doped diamond buried into non-doped defect-free high quality CVD diamond. Using this reactor the technology was developed for growth of single-crystal diamond with heavily boron doped layers 1-2 nm thick with boron concentration of (5-10) 1020 cm-3.
