Production at High in Central Au+Au and collisions at GeV in STAR
he production at high- (5.0 10.0 GeV/)
measured in minimum bias , Au+Au and central Au+Au collisions in the STAR
detector are presented. The ratio measured in is compared to
PYTHIA calculations as a test of perturbative quantum chromodynamics (pQCD)
that describes reasonably well particle production from hard processes. The
nuclear modification factor are also presented. In collisions,
charged pions and (anti-)protons are measured in the range 5.0
15.0 GeV/ and the anti-particle to particle ratio and the baryon to meson
ratios of these hadrons are discussed.Comment: 4 pages, 8 figures, proccedings for QM200
Design and fabrication of a data logger for atmospheric pressure, temperature and relative humidity for gas-filled detector development
A novel instrument has been developed to monitor and record the ambient pa-
rameters such as temperature, atmospheric pressure and relative humidity. These
parameters are very essential for understanding the characteristics such as
gain of gas filled detectors like Gas Electron Multiplier (GEM) and Multi Wire
Propor- tional Counter (MWPC). In this article the details of the design,
fabrication and operation processes of the device has been presented.Comment: 11 pages, 12 figure
