Microplasmotron and its Biomedical Applications
The function of a microplasmotron is based on the use of a plasma flow with an average mass temperature of less than 40 degrees Celsius (cold plasma). The plasma generating matter is water or atmospheric air.
The microplasmotron produces cold plasma that includes electrons, ions, medium particles (water), and radiation. These components effectively kill wound microbes ensuring 100% sterilization.
The biomedical microplasmotron has several unique features:
- easy to operate;
- precise work due to the size of a plasma jet;
- short processing time — it takes approximately 5 minutes to completely sterilize severe wounds;
Applications:
- surgery — a perfect wound sterilizer;
- physiotherapy — effective treatment of old chronic wounds and skin diseases. Having no side effects, it may replace antibiotics;
- ophthalmology — eye ceratit treatment;
- cosmetology — treatment of skin diseases (e.g. eczema);
- dentistry;
- veterinary, and other.

UV Air and Water Disinfection
The ultra-violet (UV) installation for water disinfection Vita was designed and constructed in collaboration with the Institute of Thermophysics, SB RAS (Novosibirsk). This installation is based on a unique electrodeless induction lamp.
Vita works as follows: it consists of an outer shell and a quartz casing with a mounted induction UV lamp. Water flows in the gap between the outer shell and the quartz casing, in which water is being disinfected. In the outer shell, there is a quartz window for intensity control of UV radiation. The installation is equipped with a self-cleaning device.
The induction UV lamp (induction UV lamp) is a closed, torus-like bulb filled with 100 Pa argon and mercury amalgam. Ferrite magnetic conductors initiate and supply electric discharge in the bulb that serves as a secondary coil of the transformer. The absence of electrodes extends the service life up to 100 thousand hours — that is 10 times higher than the service life of gas discharge lamps with electrodes.
Applications:
- drinking water disinfection;
- production of beverages, juices, pure water;
- disinfection of reused and run-off water.
Competitive advantages of the UV installations Vita are as follows:
- 10 — 20 m3/h productivity;
- 2 — 3 times reduction of operational costs and production expenses;
- 10 — 15% lower electric energy consumption compared with electrode based gas discharge lamps;
- insignificant (5%) intensity reduction by the end of the service life.

Data Acquisition and Control Systems
Developed at REC Plasma distributed supervisory data acquisition and control system makes it possible to access remote physical equipment via Internet/Intranet, thus, networking automated technological and research installations. A communication server provides access to hardware and connects equipment servers into integrated information system.
Advantages of the system:
- unique technological equipment is immediately networked based on the module principle through working interfaces CAMAC, GPIB, CAN, SPI;
- the complex of automated networking places is based on graphical presentation environments (mostly Lab View);
- wireless data transfer and control using software-hardware of Nanonet and IEE 802.15.4 standards applied for power saving purposes;
- data transfer among elements of the system based on developed reliable protocols;
- data acquisition, storing and protection by means of modern data base engines;
- remote administering;
Developed algorithms and protocols laid the ground for the network of online temperature sensors distributed across the territory of Russia.
Up-to-date investigations are devoted to various applications of mobile and self-tunable power saving networks of sensors based on wireless communication of IEEE 802.15.4 standard (ZigBee and Nanonet).
