  1. Particle Accelerators for Research and for Medicine Prof. Ted Wilson (CERN and Oxford University) based on the book: ISBN-013 978-981-270-070-4 http://www.enginesofdiscovery.com/ This talk: http://www.enginesofdiscovery.com/eod.pdf

  2. The race to high energies Rutherford fired the starting pistol At the Royal Society in 1928 he said “I have long hoped for a source of positive particles more energetic than those emitted from natural radioactive substances”. Engines of Discovery

  3. The Large Hadron Collider (LHC) The LHC, at CERN, is the primary tool to which high-energy physicists are looking. The hope is to discover the Higgs particle. The machine is 28 km in circumference.

  4. An “exploded” diagram of the ATLAS detector, for the LHC.

  5. Wideroe invented the Linac • Particle gains energy at each gap • Lengths of drift tubes follow increasing velocity • Spacing becomes regular as v approaches c Engines of Discovery

  6. Magnet r Vdee~ Cyclotron + • At all radii particles cross acceleration gap at same moment !

  7. The 60-inch cyclotron. The picture was taken in 1939.

  8. Spect diagnosis

  9. Linacs – an idea waiting for a technology Luis Alvarez Ed Ginzton Engines of Discovery

  10. The Dual Axis Radiological Hydrodynamic Test Facility This device is devoted to examining nuclear weapons from two axes rather than just one. This reveals departures from cylindrical symmetry which is a sign of aging which can seriously affect performance Induction Linacs The Dual Axis Radiological Hydrodynamic Test Facility This device is to examine nuclear weapons from two axes to reveal departures from cylindrical symmetry which is a sign of aging. The induction accelerator, FXR, at Lawrence Livermore, to study the behavior of the implosion process in nuclear weapons

  11. The Synchrotron

  12. First electron synchroton This 300 MeV electron synchroton at the General Electric Co. at Schenectady, built in the late 1940s. The photograph shows a beam of synchrotron radiation emerging. Engines of Discovery
