摘要：

The performance of a prototype drift chamber operating in a He-based gas mixture as a specific ionisation detector is presented. In spite of the small number of primary ions, Helium performs quite satisfactorily in measuring energy losses for charged particles: with 50 GeV/c pions, we have measured in a 90% He-10% iC(4)H(10) mixture a relative energy loss resolution of 3.1% with 75 samples 3 cm long, using a modified Truncated Mean technique with 80% accepted fraction. The dependence of the resolution on several parameters such as the operating voltage, the truncation fraction, the number and length of the samples is discussed. (C) 1998 Elsevier Science B.V.
