Book Description
The most spectacular of the new high energy approaches to nuclear physics is the field of relativistic heavy ion collisions, for which it is anticipated that construction of the Relativistic Heavy Ion Collider (RHIC) facility will begin soon. Here the goal is to subject large volumes of nuclear matter to such extreme conditions of temperature and pressure that a new form of matter is produced in which the recognizable components are not the familiar neutrons and protons, but are quarks. This paper discusses the RHIC project of the experiments and detectors associated with it. 10 refs., 4 figs.

Book Description
We have now seen the first results from experiments with high energy nuclear beams at Brookhaven and CERN. These experiments, which began about a year ago, use fixed targets at the AGS and SPS. These programs have begun with relatively light ions (A less than or equal to 32 amu) to explore states of compressed nuclear matter in which high energy density is achieved in an environment of high baryon density at energies near the maximum for nuclear stopping. The widespread interest and excitement which these experiments have generated is due in large part to the fact that they are providing the first glimpse of what is expected to be an entire new regime of physical phenomena, and that these experiments will be followed in the near future by measurements with much higher beam masses and much higher collision energies. This is the mission of the Relativistic Heavy Ion Collider (RHIC) project now being prepared for construction at Brookhaven. The status of the RHIC project is discussed, including accelerator design, experiments and detectors.

Book Description
Since 1980 there has been considerable interest at Brookhaven in exploiting the existence of the Colliding Beam Accelerator, CBA, earlier referred to as Isabelle, for the generation of heavy ion collisions at very high energies. The only requirement for a heavy ion collider would have been for an energy booster for the Tandem accelerator and a tunnel and magnet transport system to the AGS. For a few million dollars heavy ions up to nearly 200 GeV/amu could be collided with luminosities of 1027 to 1028/cm2 sec in experimental halls with ideal facilities for heavy ion physics studies. Although the CBA project has been stopped, it is still true that Brookhaven has in place enormous advantages for constructing a heavy ion collider. This paper describes a design that exploits those advantages. It uses the tunnel and other civil construction, the refrigerator, vacuum equipment, injection line components, and the magnet design for which there is expertise and a production facility in place. The result is a machine that appears quite different than would a machine designed from first principles without access to these resources but one which is of high performance and of very attractive cost.

Book Description
The Relativistic Heavy Ion Collider (RHIC) is a proposed research facility at Brookhaven National Laboratory to study the collision of beams of heavy ions, up to gold in mass and at beam energies up to 100 GeV/nucleon. The physics to be explored by this collider is an overlap between the traditional disciplines of nuclear physics and high energy physics and is a continuation of the planned program of light and heavy ion physics at BNL. The machine is to be constructed in the now-empty tunnel built for the former CBA project. Various other facilities to support the collider are either in place or under construction at BNL. The collider itself, including the magnets, is in an advanced state of design, and a construction start is anticipated in the next several years.

Book Description
The Relativistic Heavy Ion Collider (RHIC) facility will provide collision energies of 100 GeV/nucleon per beam for heavy ions as massive as gold. RHIC will use the existing Brookhaven AGS and Tandem Van de Graaff as injector. The new accelerator facility, which is a nuclear physics initiative, will utilize the existing facilities of the partially completed CBA project. This report discusses the physics motivation for such a facility, the status of the machine design, R and D work and preparations for experiments at RHIC.

This is the mission of the Relativistic Heavy Ion Collider (RHIC) project now being prepared for construction at Brookhaven. In this presentation the author briefly describes the experiments which are now being carried out with ions accelerated in the AGS and the plans for heavier beams in the near future with the completion of the AGS Booster Synchrotron, which is now under construction. The author then discusses the status of the RHIC project.

Book Description
The primary motivation for studying nucleus-nucleus collisions at relativistic and ultrarelativistic energies is to investigate matter at high energy densities ([var-epsilon] [much-gt] 1 GeV/fm[sup 3]). Early speculations of possible exotic states of matter focused on the astrophysical implications of abnormal states of dense nuclear matter. Field theoretical calculations predicted abnormal nuclear states and excitation of the vacuum. This generated an initial interest among particle and nuclear physicists to transform the state of the vacuum by using relativistic nucleus-nucleus collisions. Extremely high temperatures, above the Hagedorn limiting temperature, were expected and a phase transition to a system of deconfined quarks and gluons, the Quark-Gluon Plasma (QGP), was predicted. Such a phase of matter would have implications for both early cosmology and stellar evolution. The understanding of the behavior of high temperature nuclear matter is still in its early stages. However, the dynamics of the initial stages of these collisions, which involve hard parton-parton interactions, can be calculated using perturbative QCD. Various theoretical approaches have resulted in predictions that a high temperature (T [approximately] 500 MeV) gluon gas will be formed in the first instants (within 0.3 fm/c) of the collision. Furthermore, QCD lattice calculations exhibit a phase transition between a QGP and hadronic matter at a temperature near 250 MeV. Such phases of matter may have existed shortly after the Big Bang and may exist in the cores of dense stars. An important question is whether such states of matter can be created and studied in the laboratory. The Relativistic Heavy Ion Collider (RHIC) and a full complement of detector systems are being constructed at Brookhaven National Laboratory to investigate these new and fundamental properties of matter.
