Hmmmm,
The only forces that have any effect on Neutrinos are gravity, and the
weak bonding force inside the nucleus of an atom. Perhaps the neutrino
sensor has a gravitic lensing mechanism to capture more neutrinos. Further,
with the advent of nuclear dampers (which effect the strong nuclear binding
force) Maybe there is some other field similar which effects the weak force
Thus you would be able to gather a larger number of neutrinos into a confined
area for your (weak nuclear damper) field to detect them.
