Calibration of the Large Hodoscope ToF-Wall and Preliminary Results of the FIRST Experiment
No full textHadron therapy is an alternative way of treating cancerous tumors. It consists of irradiating tumors with protons (proton therapy) or light nuclei (alphas, carbon ions). The study of fragmentation processes is relevant for different fields of the physics concerning both basic research and applications. The energy range that is accessible at Heavy Ion Synchrotron SIS is of fundamental importance for shielding in space radiations, hadron-therapy and is interesting for different aspects exploring nuclear physics. The FIRST (Fragmentation of Ions Relevant for Space and Therapy) experiment has been designed to study nuclear fragmentation processes in the energy range between 100 and 1000 MeV/u (Mega Electron Volt per nucleon), measuring double differential cross sections, with respect to kinetic energy and scattering polar angle. This experiment was carried because there is a strong need of high-quality experimental data concerning C-12, O-16 and Fe-56 fragmentation on different targets. The first data taking has been performed at SIS accelerator facility of GSI Laboratory in Darmstadt (Germany) during August 2011 and a set of data has been collected using a 400 MeV/u carbon beam impinging on carbon and gold targets. This experiment helps not only for comparison purposes but also for the evolution of the space IC (Integrated Circuits) radiation damage evaluation. The experimental apparatus is based on both newly designed detectors placed around the target and on an already existing setup made of the ALADiN dipole magnet, the TP-MUSIC IV tracking ionization chamber, the ToF-Wall scintillator array and the LAND neutron detector. The above mentioned instruments have been integrated with new ones specifically designed for interaction region few centimeters around the target: a Start Counter (SC) based on a plastic scintillator, a drift chamber as Beam Monitor (BM), an automated mechanical system as a target holder, a silicon pixel detector Vertex to track charged fragments emerging from the target and a large-angle light fragment detector based on thick scintillators with solid photomultiplier, KENTROS (Kinetic Energy and Time Resolution Optimized on Scintillator). Most of the projectile fragments are produced in the forward direction, within small angles with respect to the beam direction and with velocities very close to those of carbon ions impinging on the target. The trajectories of these charged fragments fall within the ALADiN acceptance and, after magnetic bending, hit the ToF-Wall detector which enables measurements of the impinging point, arrival time and energy released in the scintillator array. In particular, we report performances and preliminary results obtained from ToF-Wall data analysis. This experiment will provide information about the secondary effects of nuclear fragments in healthy biological cell

The Complete Muhammad Ali
No full textIncluding material and photographs not included in most of the 100 other books about the champion, Ishmael Reed's The Complete Muhammad Ali is more than just a biography-it is a fascinating portrait of the 20th century and the beginning of the 21st. An honest, balanced portrayal of Ali, the book includes voices that have been omitted from other books. It charts Ali's evolution from Black Nationalism to a universalism, but does not discount the Nation of Islam and Black Nationalism's important influence on his intellectual development. Filipino American author Emil Guillermo speaks about how "The Thrilla' In Manila" brought the Philippines into the 20th century. Fans of Muhammad Ali, boxing fans, and those interested in modern African American history and the Nation of Islam will be fascinated by this biography by an accomplished American author.Intro -- DEDICATION -- INTRODUCTION -- The Curious History of an Icon -- CHAPTER 1 -- CHAPTER 2 -- CHAPTER 3 -- CHAPTER 4 -- CHAPTER 5 -- CHAPTER 6 -- CHAPTER 7 -- Did the Secret Government Fear a U.S. Muslim/Overseas Muslim Alliance? -- CHAPTER 8 -- CHAPTER 9 -- The Break Between the Prophet and his Disciple -- CHAPTER 10 -- CHAPTER 11 -- CHAPTER 12 -- The GOAT (Greatest Of All Time): Ali or Louis? -- CHAPTER 13 -- The Nation of Islam, the Mob, Showdowns in Canada and Sonny Liston -- CHAPTER 14 -- CHAPTER 15 -- The Taunts: Marketing or Racism? -- CHAPTER 16 -- CHAPTER 17 -- CHAPTER 18 -- CHAPTER 19 -- Boxing and the Brain -- CHAPTER 20 -- Ali's Feet -- CHAPTER 21 -- Mr. Dick -- CHAPTER 22 -- CHAPTER 23 -- The Opening Ceremonies, November 2005 -- CHAPTER 24 -- December 2005, Las Vegas -- CHAPTER 25 -- CHAPTER 26 -- June 16, 2004 -- CHAPTER 27 -- CHAPTER 28 -- CHAPTER 29 -- Aix-en-Provence -- CHAPTER 30 -- Ali as a Black Nationalist -- San Francisco, January 2004 Black Liberation Book Fair -- CHAPTER 31 -- January 31, 2004 -- CHAPTER 32 -- October 2005, Chicago -- CHAPTER 33 -- Why Ali remained with Elijah instead of following Malcolm -- CHAPTER 34 -- CHAPTER 35 -- February 4, 2006, Oakland, California -- CHAPTER 36 -- Like Zeus Descending from Mount Olympus -- CHAPTER 37 -- CHAPTER 38 -- Tuesday, February 28, 2006, New York -- CHAPTER 39 -- Bigger Than Boxing -- CHAPTER 40 -- Tribes Gallery, New York, April 2006 -- CHAPTER 41 -- June 2006, Louisville, Kentucky -- CHAPTER 42 -- CHAPTER 43 -- CHAPTER 45 -- Bad Company -- CHAPTER 46 -- Coxson, A Very Charming Rogue -- CHAPTER 47 -- Ali and the largest embezzlement scheme in Wells Fargo history -- CHAPTER 48 -- CHAPTER 49 -- "Lonnie is a stabilizing force."-Harry Belafonte -- October 29, 2006 -- CHAPTER 50 -- Abdul Rahman -- CHAPTER 51 -- CHAPTER 52 -- CHAPTER 53How Will Ali Be Remembered?

Faith and piety, love and obedience to the Messenger of Allah, respect for parents, respect for teachers, truth or honesty, nobility or self-respect, patience, sincerity and a simple life are moral characters. Performance characteristics also include trust, discipline, hard work, never giving up, love of the country, interest in reading or literacy knowledge, and concern for the environment
The antiproton interaction with an internal 12C target inside the HESR ring at FAIR
No full textIn order to fulfill the goal of producing higher rates of doubly strange hyperons, the ¯PANDA collaboration will use the antiproton ring HESR at the future facility FAIR. The low energy hyperon production by an antiproton beam requires to insert a solid target inside the ring. Unwanted side effects of such an insertion are the overwhelming amount of annihilations, which would make the detectors blind, and the fast depletion of the bunch, which circulates inside the ring. The choice of the target material impacts the hyperon production yield: Carbon turned out to provide enough initial hyperon deceleration and keep secondary interactions below a tolerable level. The use of a very thin Diamond target, together with beam steering techniques, seems to be a satisfactory solution to the above problems and will be described hereafter
