Underground Neutrino Observatory
The proposed next-generation underground water
Cerenkov detector to probe physics beyond the
sensitivity of the highly successful
Super-Kamiokande detector in Japan
3
The SuperK detector is a water Cerenkov
detector 40 m tall 40 m diameter stainless
steel cylinder containing 50,000 metric tons
of ultra pure water
The detector is located 1 kilometer below Mt.
Ikenoyama inside the Kamioka zinc mine.
4
The main sensitive region is 36 m high, 34 m in
dia viewed by 11,146 inward facing Hamamatsu
photomultiplier tubes surrounding 32.5 ktons of
water

SALTAs Henderson Project is launched September
29, 2004

Clear Creek High School students set up
the satellite modules

Basalt High School students move the detectors to
their 2nd location
10

• Data collected between Sept 29 Dec 8, 2004
• monitored 4 locations between depths of 2800-3900
  ft

Some preliminary observations
Rates at Henderson surface base station (10,337
ft above sea level) 2.5?rates at Lincoln, NE
(elevation 1189 ft)
Raw rates in muon telescopes seen to drop from
10 Hz (surface rate) ? 1 Hz ? 0.5 Hz ? 0.3 Hz
11
SALTA high school students are now analyzing the
data

• identifying stable
• data run periods
• bad data channels

Channel 0,1 coincidences
Channel 2,3 coincidences
and learning about the statistical nature of
random events
Students will next learn to calculate
accidental coincidence rates and
statistical error

DUSEL A National Science Foundation initiative
to establish a national underground laboratory
for research in physics, Earth and environmental
sciences, civil and Mining engineering, and the
Biosciences.
The science cuts across disciplines and
Directorates (ENG, GEO, and MPS) and provides
opportunities for transformational breakthroughs
and to educate the scientists engineers of the
21stcentury Michael S. Turner, Assistant
Director for Mathematics and Physical Science
