Target fabrication of current pulsed-power driven x-ray laser targets
The goal of the NARYA program at Sandia National Laboratories is to make a pulsed-power driven x-ray laser. Ongoing experiments on the 10 TW, 5 MA accelerator, PROTO II, have required a wide range of thin-walled, hollow cylindrical targets called soda straws. A typical soda straw consists of an inner lasant layer, a Parylene strong back layer, and an outer converter layer. Variations to this have been targets of plain Parylene straws, straws with only lasant layers, and straws with only converter layers. These straws are nominally 1.6, 3, or 6 mm in diameter and 20 mm in length. Additional components to the straws have been solid cones coated with a lasant laser of vanadium mounted within the straws. Cone specifications are shown. The solid cones have a base diameter of either 3 or 6 mm and extend 2/3 the way up the straw with a tip radius of 127 ..mu..m. Target parameters for the straws have been the following: the inner coatings ranging from 100-1000 A of vanadium, nickel, or copper; the Parylene thicknesses ranging from 1.8 - 5.0 ..mu..m; and the outer coatings ranging from 100-500 A of silver or barium, 500-4000 A of aluminum, or 2000-10,000 A of sodium fluoride. The requirements for the cones have been 4000 A and 400 A of vanadium.
