PHILIPS Super Rotalix Metal (SRM) rotating anode X-ray tube
Tube RX à anode tournante
Drehanodenröhre in Glas/Metallbauweise

This tube uses a metal housing for the area around the anode and cathode. The X-rays leave the tube via a beryllium window added to the metal housing. The metal part of the tube is earthed and thus captures stray electrons; this makes it possible to bring the tube collimator much closer to the anode than in conventional tubes, which results in a reduction in the effects of off-focal radiation.

As there is no danger of breakdown of the tube due to the vaporization (as in the case of a glass insert), it is possible to heat the filament to higher temperatures. This leads to an improvement in rating.

The Super Rotalix Metal tube was introduced in 1973.
