CHAPTER 2<br />
EXPERIMENTAL SET-UP AND<br />
TECHNIQUES USED IN PLASMA<br />
2.1 Introduction<br />
STERILIZATION<br />
The experiments described in the present thesis have been conducted on an<br />
inductively coupled plasma (ICP) device constructed in the laboratory of Electri-<br />
cal and Electronic Engineering, at Saga University [70-75]. Basically, it consists<br />
of discharge chamber with an internal single loop antenna to which the RF power<br />
is coupled. The device is similar with other ICP with internal antenna described<br />
someplace else [97]. The whole system permits to produce plasmas with prop-<br />
erties comparable with ones that are used for surface processing and allow the<br />
comparison of the results with those found by other research groups [17, 18, 57].<br />
In this chapter, the RF ICP device and techniques used in plasma sterilization<br />
are described. The section 2.2 concerns about the experimental set-up used for<br />
plasma treatments. Microbiological diagnostics used to investigate the dynamics<br />
of the microorganisms population is covered by both theoretical and experimental<br />
