Target physics results at 248 nm wavelength from the Aurora laser system high-intensity campaign
Abstract
Au and Si targets have been irradiated using the Aurora KrF laser system, and diagnosed with x ray and optical diagnostics. The x ray diagnostics were sensitive to the 0.1 to 10 keV range. Initial, manually aligned results indicate significant plasma heating and intense x ray production, with incident peak intensities on target of 1-2 x 10(exp 14) W/sq cm in a focal spot of order 500 microns diameter. Total energy delivered to the target in 36 of the available 48 target beams was approximately 1200 J in pulses with FWHM in the 3 to 5 ns range. M-band radiation was observed from Au foil targets. Initial bandwidth measurements on the laser indicate approx. 20 per cm without bandwidth enhancement efforts.
