TL;DR: In this paper, a vacuum tube for producing a wide high-uniformity beam of fast accelerated electrons is described, consisting of an evacuated enclosure provided with an electron transparent window and containing an elongated cathode, accelerator electrodes and a control electrode formed by sleeves electrically insulated from one another and brought to separately adjustable potentials.

TL;DR: In this paper, a secondary foil is formed from material transparent to the passage of electrons but which forms a physical barrier between the primary foil and the cathode to prevent it from exploding.
Abstract: An electron beam (E-beam) laser has a vacuum chamber in which an E-beam terminal generates a directed stream of electrons. A primary foil which seals the chamber is in the path of the stream of electrons and permits passage of the stream of electrons to the exterior of the chamber. A cathode is positioned closely adjacent the primary foil and an anode is spaced from the foil to form an elongated laser cavity between them. The electrodes are maintained at a high electrical potential which, along with the electron beam, molecularly excites a gaseous working medium between the electrodes. A secondary foil is positioned between the cathode and the primary foil. The secondary foil is formed from material transparent to the passage of electrons but which forms a physical barrier between the primary foil and the cathode. This prevents rupturing of the primary foil when the cathode material sputters off upon arcing between the anode and the cathode.

TL;DR: In this article, a beam window is described that can be used to hermetically separate two regions (e.g., the vacuum chamber of an accelerator and the irradiation target area at atmospheric pressure).
Abstract: A beam window is described that can be used to hermetically separate two regions (e.g., the vacuum chamber of an accelerator andd the irradiation target area at atmospheric pressure). The window is composed of two domed, parallel, gas-tight sheets having a space between them. A third dimpled or corrugated sheet is interposed between the first two as a means for maintaining a separation between the first two. The space between the two window sheets is used for the flow of a cooling fluid. (T.F.H.)
