We introduce the SMC in space and time, a large coordinated space and ground-based program to study star formation processes and history, as well as variable stars, structure, kinematics and chemical evolution of the whole SMC. Here, we present the Colour-Magnitude Diagrams (CMDs) resulting from HST/ACS photometry, aimed at deriving the star formation history (SFH) in six fields of the SMC. The fields are located in the central regions, in the stellar halo, and in the wing toward the LMC. The CMDs are very deep, well beyond the oldest Main Sequence Turn-Off, and will allow us to derive the SFH over the entire Hubble time.
We describe the next set of experiments proposed in the U.S. Heavy
Ion Fusion Virtual National Laboratory, the so-called Integrated Beam
Experiment (IBX). The purpose of IBX is to investigate in an integrated
manner the processes and manipulations necessary for a heavy ion fusion
induction accelerator. The IBX experiment will demonstrate injection,
acceleration, compression, bending, and final focus of a heavy ion beam
at significant line charge density. Preliminary conceptual designs are
presented and issues and trade-offs are discussed. Plans are also
described for the step after IBX, the Integrated Research Experiment
(IRE), which will carry out significant target experiments.
The heavy ion fusion program is developing single aperture
superconducting quadrupoles based on NbTi conductor, for use
in the High Current Experiment at Lawrence Berkeley National
Laboratory. Following the fabrication and testing of prototypes
using two different approaches, a baseline design has been selected
and further optimized. A prototype cryostat for a quadrupole
doublet, with features to accommodate induction acceleration
modules, is being fabricated. The single aperture magnet was
derived from a conceptual design of a quadrupole array magnet
for multibeam transport. Progress on the development of
superconducting quadrupole arrays for future experiments is
