Book Description
Plasma Spectroscopy develops the foundation of spectroscopy for plasmas containing quasi-monochromatic electric fields in the microwaves or optical range. This topic is of major importance for plasma spectroscopy and the diagnostic of technological microwave and radiofrequency discharges, plasma lasers of microwave, optical, and x-ray ranges, pulsed discharges employed as advanced radiation sources, magnetic and laser fusion, and ionospheric and astrophysical plasmas. This monograph presents novel nonlinear-optical methods for theoretical analysis of radiation of quantum systems in media, describes principles for measuring the field and plasma parameters, and discusses their practical applications.

Book Description
The gyrotron microwave source is driven by the Michigan Electron Long Beam Accelerator (MELBA) which operates at -0.8 MV, 1-10 kA, and 0.5-1.5 microsecond pulselength. The correlation was measured between optical spectroscopic emission versus microwave power and pulselength. It was found that the optical emission from hydrogen H-alpha radiation was correlated with microwave power and inversely related to microwave pulselength. The physical mechanism is related to plasma accreted from water vapor on the inside of the microwave cavity and collector. This water is ablated and dissociated to release hydrogen. (A continuing AFOSR/MURI program is exploring techniques to remove water from surfaces by RF plasma processing.) The microwave network analyzer was utilized to obtain cold tests of microwave structures in a rectangular-cross-section gyrotron and a coaxial gyrotron. The primary cold-cavity modes were measured and agreed very well with the results of heterodyned high power microwave signals analyzed by time-frequency analysis. Frequency chirping and mode hopping due to voltage fluctuations were observed as other possible causes of pulse shortening.
