Toroidal cell and battery
A toroidal storage battery designed to handle relatively high amp-hour loads is described. The cell includes a wound core disposed within a pair of toroidal channel shaped electrodes spaced apart by nylon insulator. The shape of the case electrodes of this toroidal cell allows a first planar doughnut shaped surface and the inner cylindrical case wall to be used as a first electrode and a second planar doughnut shaped surface and the outer cylindrical case wall to be used as a second electrode. Connectors may be used to stack two or more toroidal cells together by connecting substantially the entire surface area of the first electrode of a first cell to substantially the entire surface area of the second electrode of a second cell. The central cavity of each toroidal cell may be used as a conduit for pumping a fluid through the toroidal cell to thereby cool the cell
Relativistic Heavy Ion Physics in the New Millennium
The field of relativistic heavy ion physics has seen significant advancement
in the new millennium toward a greater understanding of QCD at high
temperatures with the commissioning and operation of the Relativistic Heavy Ion
Collider. Here we review progress in the field as presented in a set of
lectures at the Lake Louise Winter Institute on Fundamental Interactions in
February 2004.Comment: 30 pages, 17 figures, Lake Louise Winter Institute on Fundamental

First results from RHIC: What are they telling us?
The Relativistic Heavy Ion Collider (RHIC) facility at Brookhaven National
Laboratory is the first accelerator specifically constructed for the study of
very hot and dense nuclear matter. At sufficiently high temperature, nuclear
matter is expected to undergo a phase transition to a quark-gluon plasma. It is
the specific goal of the field to study the nature of this plasma and
understand the phase transitions between different states. The RHIC accelerator
along with four experiments BRAHMS, PHENIX, PHOBOS, and STAR were commissioned
last year with first collisions occurring in June 2000. Presented here are the
first results from low luminosity beam in Run I. They are a glimpse of the
wealth of physics to be extracted from the RHIC program over the next several
years.Comment: Invited Talk at the International Nuclear Physics Conference

Strangeness Production as a Diagnostic Tool for Understanding Heavy Ion Reactions
Strangeness production has long been proposed as a diagnostic tool for
understanding the dynamics of relativistic heavy ion collisions. In this
presentation we review the traditional picture of strangeness enhancement as a
signature for quark-gluon plasma formation. We then review, in order, some
experimental data on strange particle production in , ,
, proton-nucleus and nucleus-nucleus collisions. This is not a
comprehensive review, but rather an emphasis of a few significant points. Any
clear interpretation of strange particle yields measured in heavy ion reactions
is impossible without a physical understanding of the production mechanisms in
elementary particle collisions.Comment: 6 pages, 2 figures (in eps) talk given at XXXI International
