to all:

student working with plasmas...have a question: i have a small
cylindrical plasma approx. 1.5cm in length and surrounding the vacuum
camber wall is a coil (current transformer). this coil is connected to a
oscilloscope, when the plasma is formed there is a characteristic
(unique to the plasma formation) 'spike'. i have assumed this is a
measurement of the plasma current, is this correct? can i use the
current to calculate the resistance of the plasma (v/i = r) then in-turn
calculate the temperature of the plasma with the resistance? what is the
equation? thanks in advance.
