Mirrors that are electron transparent for use in free-electron-laser oscillators
Abstract
The surface motion of a gold-coated Mylar pellicle was measured interferometrically while the pellicle was subjected to bombardment from a 15-MeV, 40-mA pulsed electron beam. No surface motion as large as 0.3 micron was observed during the electron pulse. A radiation dose of 5 x 10 to the 7th rad did not damage the surface. The results show that this foil can be used as an end mirror in free-electron-laser oscillators.
