Previous published results of closed vessel investigations indicated that classical primers (electric or percussion with black powder bedding) when used with LOVA propellants cause unstable burning, deflagration or even lack of ignition. CPG is one of the most reliable ignition sources which make possible a reduction of temperature gradient effect and control combustion process. Comparable tests of black powder and plasma ignition in closed vessel with conventional NC propellant were done. Shorter ignition time while using plasma was achieved.

Stable operation of microwave plasma generator with a good efficiency of power transfer to the plasma needs to take into account a few of important factors. Namely the geometry of the wave launching region and discharge conditions. This report include experimental results on influence of this factors on the tuning characteristics of an atmospheric pressure Surfaguide-type plasma generator.

Prezentowany mikrofalowy generator mikroplazmy jest urządzeniem wytwarzającym plazmę pod ciśnieniem atmosferycznym. Mikroplazma w tym przypadku wzbudzana jest mikrofalami o częstotliwości 2,45 GHz i mocy od 40 W do 300 W. Jako gaz roboczy zastosowano azot. Długość i szerokość płomienia plazmy wynosi odpowiednio 1,5-25 mm i 1,5-10 mm. Jednym z możliwych zastosowań generatora mikroplazmy jest oczyszczanie i aktywacja materiałów.

he microwave microplasma generator is a device used to produce small non-thermal plasma at atmospheric pressure. In our experiment the microplasma is generated by using 2,45 GHz microwaves at powers between 40 W to 300 W and nitrogen as the working gas. The length and diameter of plasma jet is 1,5-25 mm and 1,5-10 mm, respectively. One of the application of the microwave microplasma generator is the tissue and material treatment.

Polymers are the most often applicable materials in biomedicine. Technical developments require materials with specific surface properties. Low temperature plasma treatment is a method that competes with a classic physical or chemical treatment due to its time saving, economy. It also ensures modification of very thin surfaces of materials without any changes in bulk properties. The article describes plasma techniques that modify materials which are used as substrates for proteins immobilisation, cellular or tissue cultures and materials which are exploited to produce artificial organs. Author focused on the popular polymers: polyarylosulfones, polyurethanes and polyacrylonitrile and its modification to various application: artificial organs, cellular and tissue cultures, bioreactors, biosensors and medicine dosage. The paper also provides the description of some technical solutions concerning plasma reactors with both vacuous and atmospheric pressure.
