  • A Brief History and Review of Accelerators
    A BRIEF HISTORY AND REVIEW OF ACCELERATORS P.J. Bryant CERN, Geneva, Switzerland ABSTRACT The history of accelerators is traced from three separate roots, through a rapid development to the present day. The well-known Livingston chart is used to illustrate how spectacular this development has been with, on average, an increase of one and a half orders of magnitude in energy per decade, since the early thirties. Several present-day accelerators are reviewed along with plans and hopes for the future. 1 . INTRODUCTION High-energy physics research has always been the driving force behind the development of particle accelerators. They started life in physics research laboratories in glass envelopes sealed with varnish and putty with shining electrodes and frequent discharges, but they have long since outgrown this environment to become large-scale facilities offering services to large communities. Although the particle physics community is still the main group, they have been joined by others of whom the synchrotron light users are the largest and fastest growing. There is also an increasing interest in radiation therapy in the medical world and industry has been a long-time user of ion implantation and many other applications. Consequently accelerators now constitute a field of activity in their own right with professional physicists and engineers dedicated to their study, construction and operation. This paper will describe the early history of accelerators, review the important milestones in their development up to the present day and take a preview of future plans and hopes. 2 . HISTORICAL ROOTS The early history of accelerators can be traced from three separate roots.

  • Concept of an Accelerator-Driven Advanced Nuclear Energy System
    Article Concept of an Accelerator-Driven Advanced Nuclear Energy System Xuesong Yan, Lei Yang *, Xunchao Zhang and Wenlong Zhan Institute of Modern Physics, Chinese Academy of Sciences, Lanzhou 730000, China; [email protected] (X.Y.); [email protected] (X.Z.); [email protected] (W.Z.) * Correspondence: [email protected]; Tel.: +86-931-4969-187 Academic Editor: Hiroshi Sekimoto Received: 24 March 2017; Accepted: 10 May 2017; Published: 7 July 2017 Abstract: The utilization of clean energy is a matter of primary importance for sustainable development as well as a vital approach for solving worldwide energy-related issues. If the low utilization rate of nuclear fuel, nuclear proliferation, and insufficient nuclear safety can be solved, nuclear fission energy could be used as a sustainable and low-carbon clean energy form for thousands of years, providing steady and base-load electrical resources. To address these challenges, we propose an accelerator-driven advanced nuclear energy system (ADANES), consisting of a burner system and a fuel recycle system. In ADANES, the ideal utilization rate of nuclear fuel will be >95%, and the final disposal of nuclear waste will be minimized. The design of a high-temperature ceramic reactor makes the burner system safer. Part of fission products (FPs) are removed during the simple reprocessing in the fuel recycle system, significantly reducing the risks of nuclear proliferation of nuclear technology and materials. The ADANES concept integrates nuclear waste transmutation, nuclear fuel breeding, and safety power production, with an ideal closed loop operation of nuclear fission energy, constituting a major innovation of great potential interest for future energy applications.

  • Particle Accelerators
    Particle Accelerators By Stephen Lucas The subatomic Shakespeare of St.Neots Purposes of this presentation… To be able to explain how different particle accelerators work. To be able to explain the role of magnetic fields in particle accelerators. How the magnetic force provides the centripetal force in particle accelerators. Why have particle accelerators? They enable similarly charged particles to get close to each other - e.g. Rutherford blasted alpha particles at a thin piece of gold foil, in order to get the positively charged alpha particle near to the nucleus of a gold atom, high energies were needed to overcome the electrostatic force of repulsion. The more energy given to particles, the shorter their de Broglie wavelength (λ = h/mv), therefore the greater the detail that can be investigated using them as a probe e.g. – at the Stanford Linear Accelerator, electrons were accelerated to high energies and smashed into protons and neutrons revealing charge concentrated at three points – quarks. Colliding particles together, the energy is re-distributed producing new particles. The higher the collision energy the larger the mass of the particles that can be produced. E = mc2 The types of particle accelerator Linear Accelerators or a LINAC Cyclotron Synchrotron Basic Principles All accelerators are based on the same principle. A charged particle accelerates between a gap between two electrodes when there is a potential difference between them. Energy transferred, Ek = Charge, C x p.d, V Joules (J) Coulombs (C) Volts (V) Ek = QV Converting to electron volts 1 eV is the energy transferred to an electron when it moves through a potential difference of 1V.

Mitsubishi Heavy Industries, Ltd. (MHI) has provided domestic and overseas research institutions with several types of accelerating cavities or structures, which are the heart of an accelerator. We are also internally developing state-of-the-art accelerator manufacturing technologies. The ultra-compact accelerating structure we have thus developed is mounted on our Vero4DRT high-precision radiation therapy equipment (marketed under the MHI-TM2000 Linear Accelerator System brand name). This report introduces our superconducting accelerating cavities, normal-conducting accelerating structures and radiation therapy equipment as applied products thereof. |1. Superconducting accelerating cavities 1.1 Features Superconducting accelerating cavities can lower electrical resistance to nearly zero by cooling the niobium constituting the cavities down to an extremely low temperature by using of refrigerants such as liquid helium and thereby achieving superconductivity.

  • Linear Accelerator for Radioisotope Production

Stovail t Los Alamos National Laboratory Los Alamos, New Mexico 87545 A LINEAR ACCELERATOR FOR RADIOISOTOPE PRODUCTION by L. D. Hansborough, P.. W. Harnm, and J. E. Stovall ABSTRACT A 200- to 500-MA source of 70- to 90-MeV protons would be a valuable asset to the nuclear medicine program. A linear accelerator (linac) can achieve this performance, and it can be extended to even higher energies and currents. Variable energy and current options are available. A 70-MeV linac is described, based on recent innovations in linear accelerator technology; it would be 27.3 m long and cost ~?6 million. By operating the radio-frequency (rf) power system at a level necess.-.ry to produce a 500-uA bedm current, the cost of power deposited in the radioisotope- production target is comparable with existing cyclotrons. If the rf-power system is operated at full power, the same accelerator is capable of producing an 1140-uA beam, and the cost per beam watt on the target is less than half that of comparable cyclotrons. I. MEDICAL RADIOISOTOPE PRODUCTION Nuclear medicine is a major medical specialty that provides noninvasive, cost-effective, dynamic-function information that is clinically useful in diag¬ nosing human diseases. Reactors have produced radioactive isotopes of practi¬ cally every element. Clever techniques have been developed for recovering the high specific-activity products from uranium fission (Mo, I, and ^Xe) and from fast-neutron-induced (n,p) and (n,a) reactions ( K, Mn, Co, Cu, 132 Cs, etc.).
