    A Bragg curve detector (BCD) has been designed and built to be used for AMS purposes. Its design is described and its performance, obtained in tests at the Australian National University (ANU), is reported. At a 36Cl energy of 154 MeV, the energy resolution was found to be 0.38%, and the charge resolution 1.3%. The 36Cl and 36S are completely discriminated. Good separation was also achieved at 64 MeV, and a measurement at this energy of the 36Cl/Cl ratio of a sample measured previously at 154 MeV with the standard ANU ionization detector agreed well with the earlier value. This very simple detector has been shown to be suitable for use in AMS programs.
