MODERN X-RAY PLANT.—Illustrations of some of the latest type of X-ray equipment. Enormously high voltages are used to produce very powerful rays, and an entirely new technique has been evolved to produce these voltages, control the dangerous currents, cool the X-ray generating tubes, and protect the personnel from the risk of exposure to the rays. The plant illustrated is part of that installed in the Lambeth Hospital, London. One picture shows part of the “machine room." In the lower part of the picture is a 200,000-volt generator. Above it is shown a pump to circulate cooling Water. On the right is the steel framework carrying a “cannon” containing the X-ray tube; part of the "cannon" can be seen. The black cable immediately to the left of the framework carries the 200,000-volt supply to the tube. The other photograph shows the “cannon” projecting into the treatment room, over the patients’ table. X-rays are directed downwards by the small tubular fitting below the “cannon.” The hospital equipment comprises two 200,000-volt “cannons” and one operating at 400,000 volts.
