Sterilisation by Ecr Plasma
نویسندگان
چکیده
Microwave plasma was built to produce plasma in axial direction. Plasma was initiated in a Plaxy Glass made vacuum tube by 2.45GHz commercial magnetron and meanwhile system was driven by 14 Amperes DC current passing through 16cm inner diameter toroid. Measurements with a Longmuir probe and ICCD for optical spectrometry were used to characterize internal parameters like electron density, electron temperature and different properties of the heavy particles. This study presents the bacteria disinfection capability of ECR based plasma system. Those are gram positive and gram negative bacteria that refers to structure of cell wall. The sterilization efficiency of Microwave plasma was found to be over 99, 5 % in Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis (vegetative cell), Bacillus cereus (vegetative cell), Klebsiella pneumonia and Escherichia coli.

Successful and reliable sterilisation of medical instruments is basic requirement in every hospital and in every medical practice. Conventional sterilisation methods are often reaching their limits since new materials used in modern medical technology such as plastics cannot withstand the heat during the autoclaving or their surface is strongly modified and etched in cold sterilisation using ch...
متن کاملPolarization Reversal of Electron Cyclotron Wave Due to Radial Boundary Condition
Propagation and absorption of electromagnetic waves with electron cyclotron resonance (ECR) frequency are experimentally and theoretically investigated for the case of inhomogeneously magnetized plasma column with peripheral vacuum layer, when a left-hand polarized wave (LHPW) is selectively launched. The polarization reversal from the LHPW to the right-hand polarized wave is found to occur nea...

متن کاملPlasma heating due to X-B mode conversion in a cylindrical ECR plasma system
Extra Ordinary (X) mode conversion to Bernstein wave near Upper Hybrid Resonance (UHR) layer plays an important role in plasma heating through cyclotron resonance. Wave generation at UHR and parametric decay at high power has been observed during Electron Cyclotron Resonance (ECR) heating experiments in toroidal magnetic fusion devices. A small linear system with ECR and UHR layer within the sy...
