Neutrino

- p46 sec 4.2 "... neutrino oscillations are the cause of the deficits of 1/3 to 1/2 in the measured νe flux relative to the SSM (Standard Solar Model)
The Neutrino Hunters
523.0197 Jayaward 2013 Hillsboro PL
p006 IceCube 86 cables with 60 basketball-sized globes with photomultiplier tubes
neutrino -> muon -> light -> path and energy
- p016 $270M, Francis Halzen U-Wisc
- p019 Greenland test, Amanda in 1992
- p021 one hole, 4800 gallons gas, melting 200,000 gallons water. Total 6 austral summers, complete December 2010, 9000 ft MSL
- p022 2 PeV events
- p009 Hitoshi Murayama, U-Tokyo, UCB: 1 billion neutrinos per atom in universe
- p009 100 trillion solar neutrinos from the "pass through body" every second
cross section est 0.1 m2 ?
http://arxiv.org/pdf/astro-ph/0210032v1.pdf pg 3 bottom: 1e11/cm2-s, hence 1e14 n/ 0.1 m2-s or 1e15 n/m2-s
26.2 MeV / 2 neutrinos, or 2.1-12 J produced per neutrino emitted, hence 7e14 n/m2-sec per 1366 watts
- p013 Gran Sasso 2011 OPERA flub followed by ICARUS March 16 2012 confirmation of normal light speed
- p017 John Learned U-Hawaii pacific ocean detector, seawater too radioactive
