Ion and Neutral Dynamics of Ceramic Materials Formation and Atmospheric
Abstract
An ultrafast x-ray laser system and experimental apparatus have been fully constructed, calibrated and characterized. A titanium sapphire ultrafast laser is tightly focused into a rare gas jet, where high harmonics of the laser are created. A single harmonic can be isolated with a grazing incidence grating and focused on to a gaseous sample to induce photoionization. Ejected electrons are energy analyzed using a magnetic bottle time-of-flight spectrometer. Harmonics up to the 65% have been generated and photoelectron spectra of helium, krypton xenon, nitrogen and nitric oxide have been examined. The energy bandwidth has been experimentally determined, and the first time resolved photoelectron spectra of dissociating states of bromine have been achieved.
