Abstract:

A 3.39 micron He-Ne maser excited infrared interferometer was utilized for the investigation of time and space resolved electron density in a high temperature, dense plasma formed in the theta - pinch geometry. Dispersion of the coherent infrared radiation by the plasma electrons within an external resonator pulls the frequency of the coupled maser resonator with a resultant change in intensity. The maximum measurable electron density time variation of 3 x 1016 cm-3 us-1 is achieved with a fast In As infrared detector, the resonators are operated with low coupling and at a relatively low Q. New diagnostic information on the magnetic compression of a Deuterium plasma is presented. Author
