The Heating of the Anti-Kathode in X-Ray Work

The Heating of the Anti-Kathode in X-Ray Work SINCE the beginning of X-ray work the heating of the antikathode has caused great difficulty, and with the introduction of the Wehnelt interrupter it is even more important that this should be prevented. In other words, we all along have had more energy from the coil than could be utilised in the Crookes' tube. Many workers like myself have tried to remedy this, and various plans have been adopted to keep the anti-kathode cool. It occurred to me that if we could get a piece of platinum, fused into the glass tube itself, to act as the anti-kathode, and placed opposite the kathode, this object might be attained. Such a tube, after many attempts, has at last been made; and although the first experiments have only been successful in making small tubes, others of a larger size are at present being attempted. The advantage of this method will easily be seen, because the heating of the piece of platinum can be prevented by placing the whole tube in a fluid cooling mixture or otherwise. These tubes are difficult to make at present, but I possess one which has retained its vacuum for some weeks. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nature Springer Journals
