Proposal for an Experimental Program in Neutrino Physics and Proton Decay in the Homestake Laboratory
msra(2006)
摘要
This report is intended to describe first, the principal physics reasons for
an ambitious experimental program in neutrino physics and proton decay based on
construction of a series of massive water Cherenkov detectors located deep
underground (4850 ft) in the Homestake Mine of the South Dakota Science and
Technology Authority (SDSTA); and second, the engineering design of the
underground chambers to house the Cherenkov detector modules; and third, the
conceptual design of the water Cherenkov detectors themselves for this purpose.
Included in this document are preliminary costs and time-to-completion
estimates which have been exposed to acknowledged experts in their respective
areas. We have included some contingency factors. Nevertheless, we recognize
that much more extensive documentation and contingency estimates will be needed
for a full technical design report.
In this proposal we show the event rates and physics sensitivity for beams
from both FNAL (1300 km distant from Homestake) and BNL (2540 km distant from
Homestake). The program we propose will benefit from a beam from FNAL because
of the high intensities currently available from the Main Injector with modest
upgrades. The possibility of tuning the primary proton energy over a large
range from 30 to 120 GeV also adds considerable flexibility to the program from
FNAL.
