Times Cited Count:32 Percentile:74.89(Astronomy & Astrophysics)We report on the event structure and double helicity asymmetry () of jet production in longitudinally polarized
collisions at
= 200 GeV. Photons and charged particles were measured by the PHENIX experiment. Event structure was compared with the results from PYTHIA event generator. The production rate of reconstructed jets is satisfactorily reproduced with the next-to-leading-order perturbative QCD calculation. We measured

0.0037 at the lowest
bin and -0.0181
0.0282 at the highest
bin. The measured

distributions.

in
collisions at
= 200 and 62.4 GeV at midrapidity are measured by the PHENIX experiment at the RHIC. We present the inverse slope parameter, mean transverse momentum, and yield per unit rapidity at each energy, and compare them to other measurements at different
collisions. We also present the scaling properties such as
and
scaling and discuss the mechanism of the particle production in
collisions. The measured spectra are compared to next-to-leading order perturbative QCD calculations.

Times Cited Count:10 Percentile:55.04(Physics, Nuclear)Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled collisions. Here we extend these studies to two particle correlations where one particle is an electron from the decay of a heavy flavor meson and the other is a charged hadron from either the decay of the heavy meson or from jet fragmentation. These measurements provide more detailed information about the interaction between heavy quarks and the quark-gluon matter. We find the away-side-jet shape and yield to be modified in Au+Au collisions compared to
collisions.

Times Cited Count:35 Percentile:26.98(Physics, Fluids & Plasmas)This paper documents the public release PR08 of the International Tokamak Physics Activity profile database, which should be of particular interest to the magnetic confinement fusion community. Data from a wide variety of interesting discharges from many of the world's leading tokamak experiments are now made available in PR08, which also includes predictive simulations of an initial set of operating scenarios for ITER. In this paper we describe the discharges that have been included and the tools that are available to the reader who is interested in accessing and working with the data.

With increasing experience in the implementation of in-situ experiments, improved process understanding and more mature repository concepts, the experimental programmes at the Grimsel Test Site in Switzerland have gradually become more complex and more directly related to open questions defined by repository implementation organisations and regulatory bodies. To date, in situ radionuclide transport/retardation in fractured crystalline rocks have been studied, increasing in complexity from simple, non-sorbing to more chemically complex, strongly sorbing radionuclides. Currently, two ongoing in situ experiments at the GTS are investigating the in situ behaviour of radionuclides in the presence of clay colloids and the retardation of radionuclides under hyperalkaline conditions.
