A gas target with a very thin cylindrical window has been developed for use with the new M. I. T. multiple‐gap, broad‐range spectrograph. This gas target permits observation of reaction particles at all angles, except zero and 180°. It has been used with a window thickness of 0.5 &mgr; and a gas pressure of 1 cm Hg for (d,p) angular‐distribution experiments with a 7.5‐Mev, 0.5‐&mgr;a deuteron beam.
