The [= OscSNS =] detector design is similar in design to the [= MiniBooNE =] detector at Fermilab with the exception
of being cylindrical instead of spherical and having a higher phototube coverage and the addition of butyl-
PBD scintillator to the mineral oil, as was done in LSND. The detector consists of a 20.5 m long by 8 m diameter cylindrical tank lined with
8-in phototubes at a radius of 3.5 m (3900 detector phototubes, corresponding to 25% coverage, and 390
veto phototubes, corresponding to 2.5% coverage) and filled with 886 tonnes of mineral oil (density =0.86),
corresponding to a fiducial volume of 450 tonnes. Approximately 0.031
g/l (∼ 30 kg) of butyl-PBD scintillator will be added to the mineral oil in order to increase the light output
of low-energy particles and provide neutron detection.
The center of the OscSNS detector
is located 60 m from the Hg beam dump, in the backward direction. By placing OscSNS somewhat upstream of the beam dump, the
decay-in-flight neutrino background to the neutrino oscillation measurement will be negligible. The [= OscSNS =]
detector will be buried under 6 m of dirt (or 2 m of steel) overburden in order to provide shielding from
cosmic rays and beam-induced neutrons. New electronics are being designed for [= OscSNS =] that will use ADCs
with a faster clock speed than were used in LSND and MiniBooNE (200 [= MHz =] versus 10 MHz). Figures 5.3
and 5.4 show schematic drawings of the detector location in relation to the SNS target hall, while Figures
5.5 and 5.6 show schematic drawings of the electronics area above the detector tank.
