This book was released on 2017 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments involving heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC) produce the hottest matter known to humans, approximately 100,000 times hotter than the center of the Sun or 7 trillion degrees Celsius. In these collisions, the nucleons melt into their constituent quarks and gluons for approximately 10 yoctoseconds (1E-23 seconds). As the collision system expands and cools, the quarks and gluons combine into particles via a process called “hadronization” and subsequently stream out into the detectors. Detailed studies of these produced particles can yield information about the properties of the medium in which they were produced. Some of the produced particles, known collectively as “resonances,” have lifetimes comparable to the lifetime of the collision medium itself. More specifically, comparative studies of the relative production of short-lived resonances and possible modifications of their properties by medium effects may provide information about the conditions present in and lifetime of the collision medium. In this project, we utilize data from 24.4 million collisions of copper nuclei at center-of-mass energies of 200 GeV per nucleon pair collected by the Solenoidal Tracker At RHIC (STAR) detector to reconstruct decays of the doubly-charged Delta baryon resonance and its anti-particle. Fits to the invariant mass distribution of Delta candidates are performed as functions of transverse momentum and collision centrality and properties of the Delta resonances are extracted statistically. Specifically we look at the mass, the width, and the yield of this resonance. Comparisons of our results with previous studies from proton on proton collisions and deuteron on gold nucleus collisions, as well as with model calculations, may provide deeper insight into effects present in the collision medium as well as the lifetime of the medium itself.
Book Synopsis Polarization of Radiation Resulting from Proton-helium Atom Collisions. Part I. Research. Part Ii. Electron Spectrometer by : Edward A. Soltysik
Download or read book Polarization of Radiation Resulting from Proton-helium Atom Collisions. Part I. Research. Part Ii. Electron Spectrometer written by Edward A. Soltysik and published by . This book was released on 1969 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relative cross-sections and the polarization of the light resulting from the excitation of helium by a proton beam has been measured for four transitions. The analysis indicates that there is a small violation of the delta S = O spin rule for the excitation of the 3 triplet D and 3 triplet S states of helium by protons. Also measured was the relative cross-section and the polarization of the Balmer light resulting from the capture of an electron by an energetic proton in a collision with a helium atom. In the final study, the relative differential cross-sections for n singlet P transitions in helium with a 50-300 eV electron beam that has a useable energy resolution of 0.175 eV was measured.

Book Synopsis POLARIZED PROTON COLLISIONS AT RHIC. by :
Download or read book POLARIZED PROTON COLLISIONS AT RHIC. written by and published by . This book was released on 2005 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Relativistic Heavy Ion Collider provides not only collisions of ions but also collisions of polarized protons. In a circular accelerator, the polarization of polarized proton beam can be partially or fully lost when a spin depolarizing resonance is encountered. To preserve the beam polarization during acceleration, two full Siberian snakes were employed in RHIC. In 2002, polarized proton beams were first accelerated to 100 GeV and collided in RHIC. Beams were brought into collisions with longitudinal polarization at the experiments STAR and PHENIX by using spin rotators. Optimizing polarization transmission efficiency and improving luminosity performance are significant challenges. Currently, the luminosity lifetime in RHIC is limited by the beam-beam effect. The current state of RHIC polarized proton program, including its dedicated physics run in 2005 and efforts to optimize luminosity production in beam-beam limited conditions are reported.

Book Synopsis Radiological Safety Aspects of the Operation of Proton Accelerators by : Ralph H. Thomas
Download or read book Radiological Safety Aspects of the Operation of Proton Accelerators written by Ralph H. Thomas and published by . This book was released on 1988 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report serves as a guide for the planning and implementation of radiation protection programmes for all types of positive ion accelerators. The basic types of accelerators are briefly described, followed by a detailed description of several installations covering the energy range from 10 MeV to 500 GeV. Special emphasis is given to the production of ionizing radiation and its transmission through shielding, computer techniques for shield design, radiation measurement and interpretation, and the radiological impact of accelerators on the environment. Extensive references are given so the book can serve as a source to the published literature.

Book Synopsis Polarized Protons and RHIC. Based on a Presentation to the Brookhaven PAC in August 1991 by :
Download or read book Polarized Protons and RHIC. Based on a Presentation to the Brookhaven PAC in August 1991 written by and published by . This book was released on 1991 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: RHIC, the heavy ion collider being built at Brookhaven, offers an exciting opportunity to collide highly polarized protons at high energy and luminosity. This new facility would combine the existing AGS polarized proton capability with the new Booster/Accumulator and spin rotators to achieve collisions between intense beams of polarized protons at a collision energy of 500 GeV. At this energy and the expected luminosity of 2 x 1032 cm2/second physics probes will include high P{sub T} jets, direct photons, Drell-Yan, W{sup {plus_minus}}, and heavy quarks. The accessible physics includes study of the spin content of the proton, particularly gluon and antiquark polarization, study of large PQCD-predicted asymmetries for parton-parton subprocesses, and parity violation studies and searches. The proton spin direction at a RHIC crossing can be longitudinal or transverse and can alternate bunch-to-bunch giving exquisite control of systematic errors. At RHIC double spin experiments can be done with pure beams and the energy and luminosity open a new domain for probing the physics of spin. An international collaboration is forming which proposes to exploit the unique physics available from a polarized RHIC. Important steps, leading to a polarized RHIC, have been taken. The AGS has already accelerated polarized protons. A new Booster/Accumulator has been commissioned. A beautiful series of machine experiments at Indian University have verified that spin rotators indeed remove spin resonance behavior, which is the key to achieving polarized proton acceleration to high energy. E880, an accelerator experiment which will build, install, and test a Siberian Snake in the AGS, was approved by the Brookhaven PAC in August 1991. The snake will be installed in the AGS in the summer of 1993. RHIC construction has started, with heavy ion experiments to begin in 1997.
