In the last few years John has been pursuing small neutrino and neutron detectors. He has dreamed of large reactor neutrino detectors which can be useful for arms control. A key to this may be development of instruments which are sensitive to incoming neutrino direction. This led to his invention of several new detectors, which turn out to be useful for neutrons as well. He is working with a team attempting to build compact neutron cameras, useful for locating atomic weapons material. He is currently (2018) involved the AIT/Watchman initiative, building a kiloton scale neutrino detector in Boulby, England, aiming at long range nuclear reactor monitoring.
