| Abstract | Typical x-ray sources created by the interaction of a laser pulse with solid targets produce hot debris that can damage sensitive equipment. Therefore, we investigated a debris-free source of x-ray radiation. A gas jet containing a mixture of monomers and clusters was irradiated with the frequency doubled (527nm) short pulse (<700fs) Titan laser housed in the Jupiter Laser Facility at LLNL. Two different gas mixtures were used as a target for the laser radiation: a double mixture of Kr and Ar gases and a triple mixture of Xe, Kr, and Ar. X-ray yields measured using filtered Si-diodes and absolutely calibrated PCDs are presented as a function of gas jet composition as well as delay time between the jet initiation and incidence of the laser pulse. Varying this delay time does in fact change the xray characteristics of the plasmas. Additionally, x-ray absorption by the gas jet plasma and surrounding cold gas is investigated. This will help determine how efficiently the gas jet couples to the laser radiation. X-ray pinhole images of the plasma were captured in different spectral regions to estimate the size of the x-ray radiation source. |
