Russian and Japanese neutrino detectors, "deficit"?

In a discussion of some pseudo-science (holler if you'd like the source), I came across this:

Quote:

Russia built two detectors with gallium and Japan built detectors using water and heavy water. Each detector had a characteristic range of neutrinos it could observe. But in all cases, there was a serious discrepancy between theory and reality. The neutrino deficit remained on the order of 60%.

In context, the "neutrino deficit" refers to the solar neutrino deficit, between the flux predicted by standard solar models and that observed here on (or under) Earth.

Does anyone know what "detectors" (or experiments) are being referred to? I certainly do not.
