Abstract :
This section describes both: successful commissioning of RHIC and the state of the art RHIC accelerator physics tools/applications. The commissioning provided collisions of the fully stripped gold ions at a beam energy of 65 GeV/nucleon in all four experiments “STAR”, “PHENIX”, “PHOBOS”, and “BRAHMS”. They collected more than 3 μb−1 of data. Measurements of betatron and dispersion functions have shown excellent agreement with predictions. Diagnostic results from tune-meter, wall current monitor, chromaticity, decoupling measurements, ionization beam profile monitor, Schottky monitors, etc. are shown. Progress towards stable gold ion beam stores with optimized luminosity is described [Proceedings of the HEACC2001 The 18th International Conference On High Energy Accelerators, March 26–30, 2001, Tsukuba, Japan, March, 2001]. Few major commissioning challenges are described first. The most important results, from some of the RHIC systems, are shown in the next section. In the following section bringing beams from two separate “blue” and “yellow” rings into collisions and measurements during long beam stores are described. In the summary part necessary steps and commissioning of additional systems during the next RHIC-2001 run are mentioned.
