The spallation neutron resource (SNS) being outfitted on the Oak Ridge nationwide Laboratory (ORNL) may be through some distance the top flux pulsed resource of epithermal neutrons on the earth whilst it comes on-line in 2006. even if the most thrust of the technology programme on the SNS could be fabrics technology, the power may provide amazing possibilities for examine in nuclear astrophysics, primary symmetries, and utilized nuclear physics. to check the present prestige of those fields and to start to gather the medical case and the neighborhood of researchers for destiny experiments on the SNS, a workshop on ''Astrophysics, Symmetries, and utilized Physics'' used to be held in March 2002 on the ORNL. Over 60 scientists, representing eleven US and 4 overseas universities in addition to many nationwide laboratories world wide, participated within the workshop. The complaints describe the country of study in these fields and the long run possibilities on the SNS.

9 cm2. 5 cm phototube with quartz window using Dow-Corning Sylgaard 184 for maximum UV transmission. Figure 6. Schematic design of the DANCE crystal ball. Four different shaped crystals are needed, indicated by different shadings in the figure. 22 The Monte Carlo calculations indicated that scattered neutrons could still contribute a significant background, especially in the 10 to 100 keV range of interest. Several additional methods will be employed to decrease this background. First, the measured reaction Q value can be used in many cases to discriminate between true capture events and events induced by scattered neutrons [5,6].

An example of a reaction sequence where cross sections needed for "rad-chem" diagnostics Three separate experimental components are needed to make these measurements: An intense neutron source, facilities to fabricate and handle radioactive targets, and an efficient, well characterized gamma detector. The source and detector are discussed further below; target preparation is the subject of a separate talk at this conference [3]. 18 2 Neutron Source The DANCE is being constructed on Flight Path 14 at the Manuel J.
