As a historical anecdote, SNO was not the first heavy water solar neutrino experiment. In
1965, Tom Jenkins, along with other members of Fred Reines's neutrino group at the
then Case Institute of Technology, began the construction of a 2-tonne heavy water
Cerenkov detector, complete with 55 photomultiplier tubes, in the Morton salt mine in
Ohio, USA. Unlike Chen's proposal, Jenkins had only considered the detection of
electron-type neutrinos through the charged-current reaction as other flavours were not
expected, nor had the neutral-current reaction been discovered. This experiment was
stopped in 1968 after Davis had obtained a much lower 8B solar neutrino flux than had
been predicted.
