An X-ray tube providing rectification of the high voltage by itself.  1, fiche 9, Anglais, - self%2Drectifying%20tube

Record number: 9, Textual support number: 1 OBS

This is accomplished when an X-ray tube is connected directly to the secondary windings of the high voltage transformer without any intervening rectifier. When the cathode is negative with respect to the anode, electrons will flow from the cathode filament to the anode and produce X-rays. During the next half of the electrical cycle, the anode is negative with respect to the cathode, and electrons could flow in the opposite direction. However, as long as the anode is kept cool, no electrons will be emitted from the anode, and no current will flow. The result is that of half wave rectification, where only half of the cycle of the high-voltage current is used to produce X-rays.  1, fiche 9, Anglais, - self%2Drectifying%20tube

Record number: 9, Textual support number: 2 OBS

An obvious disadvantage of self-rectification, as opposed to supplying the X-ray tube with an already rectified direct current, is that exposure times must be increased since X-ray production occurs during only half of the time the current is applied. Secondly, repeated exposures could heat the anode to such an extent that electrons are also emitted from the anode. This could result in a reverse flow of electrons in the X-ray tube with excessive heating and destruction of the filament.  1, fiche 9, Anglais, - self%2Drectifying%20tube

A simple arrangement of two cavities in series showed the feasibility of detecting traces of one gas in another. A klystron was used to generate microwave power which was fed through a wave guide to a transmission-type cavity. Another cavity was mounted in series with and tuned to the same frequency as the first; both cavities were identical except that the second had a gas inlet and outlet ports. From this measuring cell, its microwave energy was sent to a crystal detector. By frequency-modulating the klystron with a 50-cps sine wave voltage on the repeller, a burst of energy passes to the detector each time the generator frequency equals that of the cavities. The detector current is amplified and measured with an oscilloscope. At the beginning of the run, the two cavities are filled with the nitrogen carrier gas and, if the composition in one of the cavities is changed, its electrical size will change... causing a decrease of current from the detector.  1, fiche 15, Anglais, - crystal%20detector
