The National Ignition Facility (NIF) is under construction at LLNL for the Department of Energy Stockpile Stewardship
Program. It will be used for experiments for Inertial Confinement Fusion (ICF) Ignition, High Energy Density (HED) science,
and basic science. Many issues confront experimentalists who wish to design, fabricate, and install diagnostics on the NIF. To
foster this process the ICF and HED programs at LLNL have formed a diagnostic research and development group to look
at issues outside the charter of facility diagnostics (core diagnostics). We will present data from instrumentation and associated
technology that is being developed by this group. A major portion of our instrumentation work is on improvements for readout
systems. We have several efforts related to CCD device development.

This report describes the work of the Radiation Hydrodynamics Branch during FY 2003 in support of the DTRA PRS
Program. Critical issues covered are (1) issues and directions for future research, (2) zero and one-dimensional modeling of
DQ experiments, (3) enhanced energy coupling and x-ray emission in z-pinch implosions, (4) confinement and compression
of magnetic flux by plasma shells, and (6) flashover and energy coupling in the DQ machine.

The recent discovery of an intermetallic superconductor MgB2 has renewed interest in the area of superconductivity not
only because of fundamental understanding of superconductivity but also due to its potential applicability in devices such as
thermal detectors. Considerable amount of research has been devoted to obtain MgB2 films by an all in situ growth technique.
We have grown MgB2 thin films by an all in situ pulsed laser deposition process from pure B and Mg targets. Ultrathin layers
of B and Mg were deposited in a multilayer configuration. Hundreds of such Mg-B bilayers with a capping Mg layer on the
top were deposited on sapphire substrate. These depositions were done in high vacuum (approx. 10(exp -7) Torr) and at room
temperature. After deposition, such a configuration was annealed at high temperature for a short time in a forming gas (4%
H2 in Ar). The best films, obtained by this procedure, showed superconducting transition temperature approx. 30 K. These
films have been characterized by x-ray diffraction, Rutherford Backscattering Spectrometry, AC susceptibility-, resistivity-
(with and without magnetic field) and 1/f noise-measurements. The physical properties of these films will be presented and
discussed.
