Title: Status of the FAIR Facility

Abstract

A new accelerator Facility for Research with Antiproton and Ion Beams (FAIR) has been proposed by GSI. This contribution will give a short overview of the present status of the accelerator complex design with particular emphasis on the installations which employ cooling devices. Stochastic and electron cooling are foreseen in the different storage rings over a large energy range. Stochastic cooling will be applied as first cooling stage to secondary beams of rare isotopes which are produced by projectile fragmentation of heavy ions and to antiprotons which are produced from a high intensity proton beam. In the storage rings which are predominantly used for experiments the highest beam quality of the stored beam will be achieved by electron cooling.

  • Detailed planning and R and D for both, the accelerator and the experimental systems of the future international Facility for Antiproton and Ion Research (FAIR) is in progress on many fronts. It involves a wide range of activities, both at laboratories in partner countries participating in the preparatory activities as well as at GSI.This report summarizes the current situation, with emphasis on recent important developments. This includes new performance aspects of FAIR, in particular also the plans towards QCD spin physics with polarized anti-protons. An outlook on facility development and construction is given.
  • An overview is given on the international Facility for Antiproton and Ion Research (FAIR) at GSI, its science motivation and goals, the facility lay-out and characteristics, the accelerator design challenges, the schedule for construction, and the international interest/participation in the project.
  • FAIR is a new large-scale particle accelerator facility to be built at the GSI site in Germany. The research pursued at FAIR will cover a wide range of topics in nuclear and hadron physics, as well as high density plasma physics, atomic and antimatter physics, and applications in condensed matter physics and biology. The working horse of FAIR will be a 1.1km circumference double ring of rapidly cycling 100 and 300Tm synchrotrons, which will be used to produce high intensity secondary beams of short-lived radioactive ions or antiprotons. A subsequent suite of cooler and storage rings will deliver heavy ionmore » and antiproton beams of unprecedented quality. Large experimental facilities are presently being designed by the NUSTAR, PANDA, PAX, CBM, SPARC, FLAIR, HEDgeHOB and BIOMAT collaborations.« less
  • Two microscopic models, ultrarelativistic quantum molecular dynamics and quark-gluon string model, were employed to study the formation of locally equilibrated hot and dense nuclear matter in heavy-ion collisions at energies from 11.6A to 160A GeV. Analysis was performed for the fixed central cubic cell of volume V=125 fm{sup 3} and for the expanding cell that followed the growth of the central area with uniformly distributed energy. To decide whether the equilibrium was reached, results of the microscopic calculations were compared to that of the statistical thermal model. Both dynamical models indicate that the state of kinetic, thermal and chemical equilibriummore » is nearly approached at any bombarding energy after a certain relaxation period. The higher the energy, the shorter the relaxation time. Equation of state has a simple linear dependence P=a({radical}(s)){epsilon}, where a{identical_to}c{sub s}{sup 2} is the sound velocity squared. It varies from 0.12{+-}0.01 at E{sub lab}=11.6A GeV to 0.145{+-}0.005 at E{sub lab}=160A GeV. Change of the slope in a({radical}(s)) behavior occurs at E{sub lab}=40A GeV and can be assigned to the transition from baryon-rich to meson-dominated matter. The phase diagrams in the T-{mu}{sub B} plane show the presence of kinks along the lines of constant entropy per baryon. These kinks are linked to the inelastic (i.e., chemical) freeze-out in the system.« less
  • The status of FAIR, the planned 'Facility for Antiproton and Ion Research', is presented in this contribution. FAIR will be a world unique particle accelerator facility to be built as a joint project by - as of today - 16 member countries. FAIR, which is planned for construction adjacent to the GSI site in Germany, is an integrated system of particle accelerators, 2 superconducting synchrotrons and 8 storage rings, which will provide high energy and high intensity beams of ions from hydrogen to uranium with unprecedented quality and in full parallel mode. In addition highest luminosity secondary beams of raremore » isotopes and beams of antiprotons will be available. FAIR will combine physics research topics from different communities, i.e. nuclear physics, hadron physics, heavy-ion physics, plasma physics, atomic physics and accelerator development. Details of FAIR and the physics projects will be presented in this contribution.« less
