Development of a detector and data analysis for particle in the rapidity range 2.5 < vertical stroke y vertical stroke < 4 at the relativistic heavy ion collider in Brookhaven

To investigate collisions of heavy nuclei at the relativistic heavy ion collider (RHIC) in Brookhaven, the forward time projection chambers for the STAR experiment were developed at the Max-Planck-Institut fuer Physik in Munich. Topic of the thesis were the developments of detector components and of parts of the data analysis as well as the investigation of the estimated performance of the detector. Predictions simulated using different models were compared, and it was investigated to which extent fluctuations of different observables from collision to collision can be reconstructed with the detector.

The Forward Time Projection Chamber (FTPC) in STAR

Two cylindrical forward TPC detectors are described which were constructed to extend the phase space coverage of the STAR experiment to the region 2.5 < |\eta| < 4.0. For optimal use of the available space and in order to cope with the high track density of central Au+Au collisions at RHIC, a novel design was developed using radial drift in a low diffusion gas. From prototype measurements a 2-track resolution of 1-2 mm is expected

Phi production in 158-GeV/u Pb + Pb collisions

This paper reports on a comprehensive survey of priority research needs of the South African wholesale and retail sector, with the objective of providing an overview of the most significant research requirements of this significant economic sector. The survey was conducted across a spectrum of sector stakeholders including corporate, independent and informal traders, in all provinces. Survey methodology encompassed a structured priority-rating questionnaire, complemented by dialogic interviews with thought leaders in the sector, and with government and labour union officials. Considering functional areas and Standard Industry Classification divisions, the multiplicity of research problems perceived by industry stakeholders is analysed and distilled into the ‘Top Ten Research Priorities’ for consideration by the retail industry, government policy makers and academic researchers
