X-ray window sheet. X-rays are generated by accelerating electrons in a vacuum tube: When they strike a target at the positive side of the tube, x-rays are emitted. The problem then is how to let the x-rays out of the tube without letting air in. The answer is a beryllium window. Beryllium is virtually transparent to x-rays, but impervious to air. This is a sheet of beryllium from which several round pieces have been punched to make x-ray windows.
