In August 1952, Sir William Penney, the Chief Superintendent Armament Research (CSAR) at the British Ministry of Supply, and the head of the British atomic weapon development effort, notified W. A. S. Butement, the Chief Scientist at the Australian Department of Supply, of his intention to visit the site before the Hurricane test. Butement warned Penney that it was very remote, and that Beadell and his companions might well have been the first non-Aboriginal people to see the area. Sir John
Fusion power registered in 1946 by the United Kingdom Atomic Energy Authority. The inventors were Sir George Paget Thomson and Moses Blackman. This was the first detailed examination of the Z-pinch concept. Starting in 1947, two UK teams carried out small experiments based on this concept and began building a series of ever-larger experiments. The first successful man-made fusion device was the boosted fission weapon tested in 1951 in the Greenhouse Item test. This was followed by true fusion weapons in 1952's Ivy Mike, and the first practical examples in 1954's Castle Bravo. This was uncontrolled fusion. In these devices, the energy
