Device for cryogenically fabricating source material for plasma X-ray lasers

摘要

A device for fabricating a target of a lasing material and a pump material for lasing at X-ray wavelengths wherein one of the materials occurs naturally as a gas. A substrate of the other material is cooled below the freezing point of the one material occuring naturally as a gas. Then a gaseous atmosphere of the latter material is supplied to the cooled substrate so that a frozen layer of the latter material condenses onto the substrate to form the target.
