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.

Federation University Historical CollectionPhotograph - Photograph - Colour, University of Ballarat Ararat Campus, 1999, 12/07//1999
... Laby Street, Ararat, Victoria, Australia ...Federation University Australia was established on 1 January 2014. Formerly known as the University of Ballarat, its enabling legislation was the University of Ballarat Amendment (Federation University Australia) Act 2013. Although formally created as a University in 1994, the University of Ballarat has a lineage back to 1870 with the establishment of the School of Mines Ballarat, making it the third institution of higher learning to be established in Australia and the first to be established in regional Australia. On 1 January 1994, Ballarat University College became the University of Ballarat and in 1998 the University merged with three TAFE Institutes to become a dual sector institution with multiple campuses. On 1 January 2014, the University of Ballarat amalgamated with the Monash University Gippsland Campus to form Federation University Australia. The Gippsland Campus also had a long lineage dating back to 1928 with the establishment of the Yallourn Technical School which became a predecessor institution to the Gippsland College of Advanced Education formed in 1968. In 1990, it was renamed the Monash University College and in 1993 became the Gippsland Campus of Monash University. In 2016, Federation University Australia announced plans to take possession, over a two-year period, of Monash’s Berwick Campus in the south-east corridor of Melbourne. Federation University Australia, or FedUni, is headquartered in Ballarat and offers programs in Higher Education and Vocational Education and Training to regional Victoria and beyond. The University’s commitment to educational and social equity, teaching excellence, research distinction, environmental sustainability and regional capacity building has enabled it to develop in a way that draws on its proud heritage to inform its future. Its regional character sets a framework for the University’s priorities but does not constrain it from serving wider community interests, nationally and internationally. The name Federation University Australia was chosen to convey the scope and capacity of an expanded regional university with a federated network of campuses.Three colour photographs of the Federation University Ararat Campus. ararat, ararat campus, university of ballarat ararat campus, federation university ararat campus -

Jacqueline Eager Student Projects Placement, Cultural Collections 2005 In 1913 Coolidge overcame the limitation of the narrow operating range of the gas X-ray tubes with the invention of the vacuum X-ray tube. A filament heated by an electric current directly releases electrons by thermionic emission. In thermionic emission, electrons are emitted from a metal surface directly by the application of an electric current to heat a wire filament. The electrons accelerate to the anode and produce X-rays. The anode has associated cooling fins due to the high temperatures attained by the release of kinetic energy by the electrons on colliding with the anode. Internal Glass sleeve: “A941/L2593/2821”
