SNO var et neutrinoobservatorium, som befandt sig 2100 m under jordens overflade i <a href="/w/index.php?title=Creighton-minen&action=edit&redlink=1" class="new" title="Creighton-minen (ikke skrevet endnu)">Creighton-minen</a> i Sudbury, Ontario, Canada. Detektoren var designet til at registrere neutrinoer som kom fra Solen gennem deres interaktion med en meget stor tank med tungt vand.  </p><p>Detektoren var aktiv frem til 2006. SNO samarbejdet fortsatte i adskillige år med at analysere data fra eksperimentet.  </p><p>På Super Kamiokande måltes kosmiske neutrinoer. Når en neutrino kolliderer med et vandmolekyle i tanken, dannes en hurtig elektrisk ladet partikel. Herved udsendes såkaldt <a href="/wiki/Cherenkovstr%C3%A5ling" title="Cherenkovstråling">Cherenkovstråling</a>, som måles af lyssensorer i eksperimentet. Formen og intensiteten af Cherenkovstrålingen afslører, hvilken type neutrino, der har forårsaget den, og hvor den kom fra. Det viste sig, at muon-neutrinoer, som ankom direkte fra atmosfæren var mere talrige end dem, der havde rejst tværs gennem Jorden. Det antydede, at de sidstnævnte havde rejst længere og derfor havde haft længere tid til at skifte identitet til en anden type neutrino undervejs.  </p><p>På The Sudbury Neutrino Observatory målte man neutrinoer fra Solen som kun producerer elektron-neutrinoer. Reaktionerne mellem neutrinoer og det tunge vand i tanken gav mulighed for at måle både elektron-neutrinoer og alle tre neutrinoer i kombination. Man opdagede derved, at der var færre elektron-neutrinoer end forventet, mens antallet af de tre typer neutrinoer tilsammen var som forventet. Konklusionen var, at nogle af elektron-neutrinoerne havde ændret identitet. </p> <div class="mw-heading mw-heading2"><h2 id="Neutrinoers_vekselvirkning_med_andet_stof">Neutrinoers vekselvirkning med andet stof</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Neutrino&veaction=edit&section=2" title="Redigér afsnit: Neutrinoers vekselvirkning med andet stof" class="mw-editsection-visualeditor"><span>redigér</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Neutrino&action=edit&section=2" title="Edit section's source code: Neutrinoers vekselvirkning med andet stof"><span>rediger kildetekst</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Neutrinoer har så små tværsnitsarealer, at de uendelig sjældent vekselvirker med andet stof. </p><p>Milliarder af neutrinoer farer tværs gennem Jordkloden uden at komme i kontakt med dens materiale, de passerer gennem tomrummet i <a href="/wiki/Atomer" class="mw-redirect" title="Atomer">atomerne</a> uden hindring.
