The authors have developed a high-pressure /sup 3/He target based on the principle of a gas scintillation proportional counter (GSPC) to observe with high luminosity and good energy resolution tritons emitted in the capture of muons by /sup 3/He. The techniques used with this new detector are described and the first results obtained in the search for massive neutrinos which couple to muons are shown.
