    • Abstract
  • Developing the 36Cl and other medium heavy isotopes measurement at 3 MV AMS facilities is one of the vital trends in AMS measurement. To further increase suppression factor of 36S, the energy loss straggling and angular straggling of 36Cl and 36S ions in various counter gases (P10, isobutane and propane) were investigated. Some water samples were measured with the energy of 32 MeV, the results are in good agreement with the result by ion energy of 72 MeV. The results indicate that the detection limit of 36Cl with 3 MV AMS facility is approximately 36Cl/Cl≈10-14, and the uncertainty is 30% for the sample with isotopic ration 36Cl/Cl≈10-13.
