A hot D/sup +/ plasma is produced by multi-stsge magnetic compression of a cold gas containing D/sup +/. The cold gas enters a cylinder containing a weak coaxial magnetic field, and the field is increased to a high value B in a time that is short compared to the ion-ion relaxation time but long compared to the ion cyclotron period. After this initial heating, the plasma is moved, by means of a transfer magnet, into a region having a field strength about 4B, thus causing farther heating. The hot plasma is contained in this region for about 1 msec in a volume of abcut 2 liters, and achieves a density of around 10/sup 13/ ions/cm/sup 3/ and a temperature of around 3.6 deg K. Evidence for the occurrence of the fusion reactions D(D,n)He/sup 3/ and D(D,p)H/sup 3/ in this plasma is presented. (T.F.H.)
