A vacuum spark light source for the extreme ultraviolet region.
A mechanically triggered spark light source for use in the extreme uv region is described. The source is designed for precise optical placement of the spark and for compatibility with clean ultrahigh vacuum systems. The performance of this source is compared with that of a light source generated by a laser-produced metal plasma. The effect of magnetic confinement of ionic species in the spark is evident in the comparison of the spectra of the spark and the laser-produced plasma.
