Summary
X-ray tube for light work by C.H.F. Müller, known as the 'Müller 13a Tube'.
Target of nickel faced with platinum and provided with a glass mantle to cut off all subsidiary x-rays from behind target. Mica-disc vacuum regulator. The Vacuum regulator consists of a mica disc electrode at one end of a side tube which a stiff wire is taken to within sparking distance of the cathode terminal of the main tube. The heat thus generated by the current in the regulator causes the mica disc to yield up some of its occluded gas, which passes into the tube and lowers the vacuum.
