Abstract : The research was concerned with the experimental and theoretical study of the charged particle emission from metal capillaries at high electrical voltage (10 kilovolts) and containing conducting oils under pressure. Experimental techniques employed and developed under the program included shadowgraph with the repetitively pulsed Xenon arc, conventional microscopy with Xenon arc illuminators, dark field imagery with Xenon arc, stero-shadowgraph with the Xenon arc, shadowgraph with the pulsed ruby laser, and holographic microscopy with pulsed ruby and continuous wave helium-neon laser illuminators. The experimental observations demonstrated that the conducting glycerin was pulled by the applied electric field into microscopic filaments which then underwent the classical electrohydrodynamic instabilities. A byproduct of the investigations on holographic microscopy was the discovery of pulsed laser holographic interferometry. (Author)
