2.1. Microwave Plasma Steriliser
(MicroPlaSter)*
The plasma torch consists of 6 stainless steel electrodes placed inside
an aluminium cylinder of 135 mm in length. The centers of the 6 electrodes,
whose surfaces are serrated, are distributed equally at a distance of 6 mm
from the inner surface of the cylinder. 6 small plasmas are produced between
each of the electrode's tips and the inner surface of the cylinder as shown
in the figure. Gases used: Ar, He, Kr, plus additives.
2.2. Mini Plasma Steriliser
(MiniPlaSter)*
The plasma torch (left picture) consists of a serrated electrode inside a quartz
tube and an outer aluminium body. The (microwave) plasma is produced at the electrode
tip and is convected out by the gas flow as shown in the figure. Gases used:
Ar, He, Kr, plus additives. In this particular example Ar at 4 slm and a power
of 5 W. The right picture shows (color coded) the temperature distribution
inside the plasma 'flame'.
