Extractions: Ernest Walton was born in Dungarvan, Co. Waterford, in 1903, son of Methodist Minister John Walton and Anne E. Sinton. Ernest received early education in Banbridge and Cookstown and secondary education at Methodist College, Belfast. He entered Trinity College Dublin (TCD) in 1922 on scholarship and took a first class honours degree in Physics and Mathematics (1926), followed by an M.Sc. degree in 1927. He won a research scholarship to work with Ernest Rutherford (1871-1937) at the Cavendish Laboratory, Cambridge. At the time physics was going through a golden era. Albert Einstein had revolutionised the way physics looked at the world with his theory of relativity (1905, 1915). Rutherford had discovered that atoms have a tiny dense central core, the atomic nucleus, in 1910. The atomic nucleus is surrounded by a cloud of electrons and Niels Bohr had described how the electrons orbit the nucleus in 1913. And, in 1925 and 1926 Werner Heisenberg, Paul Dirac and Erwin Schrodinger, founded a new branch of physics called quantum mechanics that describes the behaviour of atoms and sub-atomic particles.

Extractions: Walton studoval matematiku a experimentální fyziku na Trinity College v Dublinu, jadernou fyziku na Trinity College v Cambridge. Zde spolupracoval s Cockcroftem ve slavné Cavendishovì laboratoøi.. V dubnu roku 1932 sestrojil s Cockcroftem zaøízení postavené ze sklenìného váleèku, vakuových trubic a autobaterií a tohoto zaøízení vyuili k urychlení protonù. Urychleným svazkem protonù bombardovali terèík z lithia. Jádra lithia roztìpili na dva atomy helia. Ukázali tak mimoøádný význam urychlovaèù pro jadernou fyziku. V roce 1934 se Walton vrátil na Trinity College do Dublinu jako vedoucí katedry fyziky. V roce 1946 byl jmenován profesorem a v roce 1974 odeel do dùchodu.

Extractions: Local Ernest Thomas Sinton Walton, Nobel Laureate and Honorary Fellow of the Institute of Physics, who died on 25 June 1995, was one of the legendary band of nuclear physicists who made 1932 an annus mirabilis . With John Cockcroft he caught the world's attention when he 'split the atom' (more properly its nucleus) by artificial means. This was no large-scale, extravagant experiment, and still less did Walton crave the great fame which he achieved. A modest man, his great skills lay in his keen mind, love of physics, and exceptional dexterity, qualities which remained with him throughout his long life. His achievement realised the alchemist's age-old dream of transmutation in a dramatically novel way. In 1919, Rutherford had already induced the nuclear reaction N + alpha = O + p using alpha particles from a radioactive source. Driven by the great man's call for 'a million volts in a soapbox', Walton and Cockcroft built an accelerator which provided a far greater and more controllable particle flux than had previously been available from radio-isotopes. The particles being accelerated were singly charged protons rather than doubly charged nuclei of helium atoms. This increased the chance of nuclear reactions occurring, as the electrostatic repulsion between projectile and target nucleus was smaller. The accelerator was built in a disused room in Rutherford's Cavendish Laboratory at Cambridge, and was supplied with several hundred kilovolts from a voltage multiplier circuit designed and built by Cockroft and Walton. Odd bits and pieces of equipment and even recycled pieces of wood and nails were used, as was standard practice in the Cavendish. Part of the apparatus is now in the Science Museum in London.

Ernest Walton: An Irish Scientist An account of walton s life entitled ernest thomas sinton walton (19031995)The Irish Scientist has been published by the Physics Department, http://groups.iop.org/HP/Archive/No17p18.htm
Extractions: Ernest Walton was one of the legendary pioneers of the twentieth century who made 1932 the annus mirabilis of experimental nuclear physics. In that year James Chadwick discovered the neutron; Carl Anderson and Seth Neddermeyer discovered the positron; Fermi articulated his theory of radioactive beta decay; and Ernest Walton and John Cockcroft split the atom (or more accurately, the nucleus) by artificial means. In their pioneering experiment. Cockcroft and Walton bombarded lithium nuclei with high energy protons linearly accelerated across a high potential difference ( ca. 700,000V). The subsequent disintegration of each lithium nucleus yielded two helium nuclei and excess energy of 17Mev. Their work gained them instant international recognition and the Nobel Prize in 1951. Their experiment was important for a number of reasons: First, it pioneered a new branch of physics in which artificially accelerated particles were used to initiate nuclear interactions in a controlled way. Second, the apparatus generated fast positive ions (in this case, protons) in greater abundance than the alpha particles from available naturally occurring radioactive sources used earlier by Rutherford to achieve nuclear transmutation: the energy and flux of the proton beam were adjustable parameters. Third, the experiment verified the predictions of the new wave mechanics and validated Gamow's calculations on tunnelling based on the new wave theory. Lawrence and others apparently failed to grasp the significance of tunnelling through the repulsive barrier surrounding the nucleus in their efforts to induce nuclear reactions. And, fourth, it was the first direct experimental verification of Einstein's mass/energy relationship

Full Wave Cockcroft-Walton Voltage Multiplier (Named after James Douglas Cockcroft and ernest thomas sinton walton, winners ofthe 1951 Nobel Prize in physics for Transmutation of atomic nuclei by http://members.tm.net/lapointe/Cockcroft_Walton.htm
Extractions: Cockcroft Walton Voltage Multiplier This is a schematic diagram for a three stage, full wave Cockcroft-Walton voltage multiplier. (Named after James Douglas Cockcroft and Ernest Thomas Sinton Walton, winners of the 1951 Nobel Prize in physics for "Transmutation of atomic nuclei by artificially accelerated atomic particles.") The diodes allow the capacitors to charge in parallel and discharge in series. More stages produce higher voltages and lower currents. The no load output voltage is simply the number of stages multiplied by the peak input voltage. For my unit, operating from a 15 kVAC (RMS) neon sign transformer, this works out to 15,000 * (square root [2]) * 3 or 63,600 volts. Here it is hooked up to (and sitting on top of) my 15 kVAC neon sign transformer, with 120 volt input. A point electrode, made from aluminum roof flashing, is suspended over the top electrode and grounded via a 23 megaohm current limiting resistor network. This picture shows a simple electrostatic motor set up and ready to run. The rotor is made from two pieces of aluminum roof flashing, held together with aluminum duct tape and sits on a needle point ground from a piece of 1/8" drill rod. The rod sits in a hole in a piece of 1/2" square copper bus bar, which is connected to the C-W output terminal with a small piece of flashing. Here I am, drawing a very impressive (and loud) 4" arc from the rim of the running motor to a grounded (no limiting resistor) steel sphere.
