Underground Neutrino Observatory
The proposed next-generation underground water Čerenkov detector
to probe physics beyond the sensitivity of the highly successful Super-Kamiokande detector in Japan
The SuperK detector is a
water Čerenkov detector
40 m tall40 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.
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
Underground Neutrino Observatory
• 650 kilotons
• active volume: 440 kilotons
20 times larger than Super-Kamiokande
major components: photomultiplier tubes, excavation, water purification system.
$500M The optimal detector depth to perform the full proposed scientific program ofUNO 4000 meters-water-equivalent
or deeper

Rates at Henderson surface base station (10,337 ft above sea level)= 2.5rates at Lincoln, NE (elevation: 1189 ft)
•Data collected between Sept 29 – Dec 8, 2004•monitored 4 locations between depths of 2800-3900 ft
Raw rates in muon telescopes seen to drop from
10 Hz (surface rate) → 1 Hz → 0.5 Hz → 0.3 Hz

Channel 0,1 coincidences
Channel 2,3 coincidences
SALTA high school students are now analyzing the data
• identifying stable data run periods• bad data channels
…and learning about the statisticalnature 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 Division (NSF)

Through CSU’s Hispanic student services office El Centro we’re coordinating a joint meeting of the local chapters of the Society of Hispanic Professional Engineers (SHPE), the American Indian Science & Engineering Society (AISES), and the National Society of Black Engineers (NSBE) where we’ll reprise presentations and hands-on activities and seek the input of the Denver area’s minority community members.
