Available in PDF, EPUB and Kindle. Book excerpt: Experimental investigation of several aspects of arcjet operation is performed using several diagnostic techniques developed here. Two techniques address the outstanding experimental problem of measurement of plume species density. These are pulsed electron beam fluorescence and two photon laser induced fluorescence. The former provides data on both molecular and atomic properties, while the latter measures only ground state atom properties. Ground state atomic hydrogen density is measured here for the first time. Current modulation velocimetry is applied to the study of plume velocity fluctuations. It is found that they exhibit no correlation with the supply current ripple and thus seem to be random.
