We studied c1E/clx in a small-cell drift chamber filled with a gas mixture of 50% He and 50%C2H6. The dE/dx resolution, measured in terms of the 80% truncated mean of 41 layer samples,was 5.2% when the incident angle of the track with respect to the wire direction was 45'. The f3-ydependence showed a smaller relativistic rise than in the case of P-10 gas. At an incident angleof 90', we observed gas gain saturation due to the space charge effect. Although this makes the737 dependence of c1E/dx weaker, the dE/dx resolution was improved. As a result, a m - Kseparation of 2cr is achieved at all incident angles for 2 GeV/c tracks.
