5 Synchrotron Radiation Sources There are more than 50 synchrotron radiation facilities in the world. In the US there are machines in Brookhaven (NSLS), Argonne (APS), SLAC: SPEAR and the LCLS, and at LBL (ALS). This intricate structure of a complex protein molecule structure has been determined by reconstructing scattered synchrotron radiation

8Engines of Discovery Linac Coherent Light Source and the European Union X-Ray Free Electron Laser (Fourth Generation) FELs, invented in the late 1970’s at Stanford are now becoming the basis of major facilities in the USA (SLAC) and Europe (DESY).They promise intense coherent radiation. The present projects expect to reach radiation of 1 Angstrom (0.1 nano- meters, 10kilo-volt radiation) ↓

11Engines of Discovery The Rare Isotope Accelerator (RIA) scheme. The heart of the facility is composed of a driver accelerator capable of accelerating every element of the periodic table up to at least 400 MeV/nucleon. Rare isotopes will be produced in a number of dedicated production targets and will be used at rest for experiments, or they can be accelerated to energies below or near the Coulomb barrier.

13Engines of Discovery A modern system for treating a patient with x-rays produced by a high energy electron beam. The system, built by Varian, shows the very precise controls for positioning of a patient. The whole device is mounted on a gantry. As the gantry is rotated, so is the accelerator and the resulting x-rays, so that the radiation can be delivered to the tumor from all directions. Cancer Therapy Machines

14Engines of Discovery A drawing showing the Japanese proton ion synchrotron, HIMAC. The facility consists of two synchrotrons, so as to maintain a continuous supply of ions (or protons) to the treatment area. The pulse of ions is synchronized with the respiration of the patient so as to minimize the effect of organ movement.

34 Conclusion I have sketched for you some of the likely future projects of accelerator physics future. Perhaps, the development of accelerators was a passing moment in the history of mankind, but it is much more likely to be an activity that will continue, producing devices not only for physics, but for an ever increasing catalogue applications enriching our everyday lives.
