Abstract

The amplitude-energy relationships for surface barrier detectors were measured for⁴He and¹²C particles, as well as the corresponding energy resolutions. It is shown that the use of¹²C beams presents no marked advantage for increasing mass or depth resolution. On the other hand pile-up phenomena are drastically reduced by using¹²C backscattering. Applications are shown to the determination of trace amounts of Sb or Yb near the surface of iron. Gold contaminations of silicon surfaces were precisely measured within minutes down to 5·10¹¹ gold atom/cm², the limiting sensitivity being of the order of 10¹⁰ atom/cm² for traces of heavy elements, such as Au, Hg, Pb, etc. Sensitivities for lighter elements are discussed.
