Plasmas and Their Medical Applications

Phase changes occur when the temperature of a system increases and fundamentally alters the behavior of the system.  Solids melt into liquids.  Liquids evaporate into gases.  For the vast majority of matter on Earth, these three phases are a comprehensive model.  Under certain conditions, gases can reach temperatures high enough to break atomic bonds, creating plasma, the fourth phase of matter.  This talk will develop a model for plasma behavior starting from the analysis of isolated charged particles and concluding with the kinetic theory of plasmas.  A precise quantitative definition of plasma will be applied to common terrestrial and artificial plasmas, such as lightning and fusion plasmas.  Over the past 20 years, atmospheric pressure plasmas have been used for a variety of medical applications including cancer therapy and cauterization.  The second half of this talk will discuss medical plasma source design and techniques for measuring medical plasma parameters.
