  1. Draft Outline for Report I. Physics Possibilities of Reactor Neutrino Experiments-  (m213) - neutrino magnetic moment- Finesse physics- structure functions- sin^2 theta W (can NuTeV result be checked?)- Search for oscillation effects of sterile neutrinos (If MiniBoone confirms LSND signal, can reactor experiments be helful?)- CPT tests (nu bar from reactor vs. solar neutrino); can new experiments improve these tests- Can detectors also be useful for supernova detection?- Can other experiments (or detector R&D) take advantage of new underground facilities near reactor?- Better measurement of absolute neutrino spectrum from reactor?

  2. II. Reactor experiment to measure A. Systematic issues common to all approaches: -- efficiency -- energy calibration -- backgroundB. General detector issues -- Choice of scintillator -- Number of detector regions -- Calibration schemes -- Movable detectorsC. Comparison of different experimental approaches -- Can we develop figures of merit to compare different experimental approaches, sites? -- What will be needed to establish a signal? For example, will some energy spectrum information be required? Will it be necessary to evaluate detector efficiency in independent ways? -- Other issues relevant for site selection (e.g., environmental impact).

  3. D. Systematic precision attainable with different experiments o. BRIEF reports on worldwide activities i. Small (CHOOZ-2): fixed 10-ton detectors at 1.1 km baseline ii. Medium: 50-ton detectors (Movable vs Fixed) iii. Large: 250-1000 ton (single or multiple far detectors -- are identical near and far detectors needed?). What is the ultimate reactor experiment?E. Sensitivity studies for different options; complementarity with acceleratorsF. Discussion of cost/timescale for different scales of experiments.III. Discussion of possible roadmap for future reactor neutrino experiments.
