Laser-Fusion Target Fabrication: Application of a Polymeric Ablator Coating to anBall-and-Disk Target Design by the Physical Vapor Deposition of Polyethylene

摘要

A technique for applying polyethylene by physical vapor deposi-tion is described. The ball-and-disk target design requires the application of a thin film of polyethylene on the front surface of the ball and substrate upon which the ball is mounted. Disk-shaped films, typically 200-um-diam by 1-um-thick, are successfully applied by this method.
