|About the Booster Neutrino Experiment (BooNE):
- BooNE is the only experiment to search the entire range
covered by the LSND oscillation signal.
- First proposed in 1997, BooNE has been collecting data
since August 2002.
- The BooNE collaboration is small by high energy physics
standards, comprising 75 physicists from 16 instiutions.
- If BooNE detects a supernova, it will send an automatic
signal to telescopes around the world describing its position.
|About the MiniBooNE detector:
- The MiniBooNE detector is a 40-foot (12-meter) diameter sphere.
- It contains 800 tons of mineral oil, which is equivalent to one
quarter of a million gallons or 44 tanker trucks.
- There are 1520 individual detectors (phototubes) lining the detector.
- The detector sees one neutrino collision every 20 seconds.
- Approximately 1 million neutrino events are collected per year.
|About the BooNE neutrino beam:
- The neutrino beam is produced using 8 GeV protons from the Fermilab booster.
- The neutrinos are delivered in bursts lasting 1.5 millionths of a second, 5 times per second.
- The BooNE horn is used to focus the intense, high-energy
particle beam and create an intense beam of neutrinos. The horn:
-operates at 170 kA for 150 millionths of a second;
-pulses five times per second;
-must be able to withstand these extreme conditions for 100 million pulses.
- The BooNE horn has already endured more pulses than any other horn ever!
- By switching the polarity of the horns, the neutrino beam can be converted into an anti-neutrino beam.
- Neutrinos come in three flavors: electron, muon, and tau.
- Neutrinos are everywhere!
- 100 trillion neutrinos pass through
our bodies every second;
- in every gallon of space, there are a million neutrinos.
- Neutrinos are created by nuclear reactions in our Sun, and carry away about 10% of the Sun's energy.
- Most neutrinos were created some 13 billion years ago, in the earliest moments of the Big Bang.
- In a supernova, neutrinos escape the imploding star faster than the light.
- If a neutrino has mass, its flavor can change midflight -- i.e. the neutrino oscillates.
