Rotating Anode X-ray Tube

Description
The investigation of the x-ray appears early on to have been a priority research topic at the University of Melbourne’s School of Physics. This interest was sparked by the appointment in 1889 of Professor T.R. Lyle. Lyle, who was head of the school until 1915, is thought to have been the first person in Australia to have taken an x-ray photograph. A copy of this photograph can be found in the School of Physics Archive. For this particular experiment Lyle actually made his own x-ray tube. His successor, Professor Laby, continued to work with x-rays. During the 1920s Laby worked on the x-ray spectra of atoms and in 1930 he co-published with Dr. C.E. Eddy, Quantitative Analysis by X-Ray Spectroscopy. Also with Eddy, Laby produced the landmark paper Sensitivity of Atomic Analysis by X-rays. Laby went on to have an x-ray spectrograph of his own design manufactured by Adam Hilger Ltd. (see cat. No. 38). School of Physics, the University of Melbourne Cat. No. 22. Jacqueline Eager Student Projects Placement, Cultural Collections 2005 A modern X-ray tube differs little from the original Coolidge tube. A minor modification is the rotating anode type that extends the life and increases the available power of the tube by presenting a new portion of the anode when required.
