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. 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 design and proposed experiments are presented for the Relativistic Heavy Ion Collider at Brookhaven. The plans are to begin with relatively light ions (A approx. = 32amu) and to extend over the mass range to A = 200. With these relativistic beams one will be able to investigate thermodynamic conditions with near-zero baryon number which can be compared with quantum chromodynamics. 14 refs., 10 figs., 3 tabs. (WRF).

Book Description
Since low energy nuclear physics research was discontinued at Brookhaven and replaced by a relativistic heavy ion program, large blocks of time became available at the Tandem Van de Graaff Facility for technological applications and for research in other areas. The main technological application has been the single event upset (SEU) testing of microelectronic devices and this activity has been steadily increasing over the last few years. The ion beam requirements for this type of work are discussed and a description is given of methods used for satisfying these requirements at the Brookhaven facility. Available ion species, energies, ranges, LETs and beam intensities, purity and uniformity are discussed. Characteristics are summarized of a sophisticated and extremely user friendly test chamber and associated hardware and software installed at Brookhaven by a coalition of government agencies and made available for general use. The possibility is mentioned of extending SEU testing to higher energies by using heavy ion beams from a Booster synchrotron now under construction and from the existing large Alternating Gradient Synchrotron (AGS). Finally a brief discussion is given of compatibility with other programs and of future availability of low and high energy heavy ions for SEU testing at Brookhaven. 13 refs., 3 figs.

Book Description
The recent approval of the beam transfer line from the Tandem Van de Graaf to the AGS signals the advent of a new era of Nuclear and Particle Physics at BNL. High Energy nuclear beams are expected to be available for experiments in 1986. I will discuss the direct link between the Tandems and the AGS. Two other proposed projects, the Relativistic Heavy Ion Collider and the Synchrotron Booster, are discussed in another presentation to this conference.

Book Description
At the Relativistic Heavy Ion Collider (RHIC), scientists are investigating not only the primordial properties of the universe but also another fundamental question of particle physics: the property of "spin." A particle's spin comes from its intrinsic angular momentum and is a basic property such as charge or mass. Many existing and future high energy and nuclear physics experiments rely on accessing spin. These experiments require using beams of polarized particles, which have their spins all pointing in one direction. When used as a probe of matter, beams of polarized particles reveal details of fundamental interactions not accessible with unpolarized particles. Experiments using polarized beams also need accelerators capable of accelerating and colliding such beams while preserving polarization. Achieving this, as in so many extraordinary feats that make science discoveries possible, is easier said than done.

Book Description
A large and growing community of nuclear and high energy physicists is now embarked on a program of experiments with very high energy nuclear beams. The first round of these experiments will take place late in 1986, with fixed target experiments at the Brookhaven AGS and the CERN SPS. These programs, involving about 300 experimental physicists, will begin with relatively light ions (A approx. = 32 amu) to explore states of compressed nuclear matter in which high energy density is achieved in an environment of high baryon density. Within 2 to 3 years of this initial effort it will be possible with the Booster synchrotron to extend the mass range of AGS beams to cover essentially the entire periodic table. The next goal is then to reach much higher energies with colliding beams of heavy ions, creating thermodynamic conditions with near-zero baryon number which can be directly compared with QCD calculations, exploring the full panoply of phenomena described by Helmut Satz in his physics perspective.
