Abstract A gas-filled time-of-flight (GF-TOF) detector has been built and developed to improve the ability of isobaric identification in accelerator mass spectrometry (AMS) measurements, and a time resolution (without gas filled) of better than 350ps is achieved. The GF-TOF detector is tested by means of measuring a standard AgCl (36Cl/Cl =7.6×10-9g/g) sample with the 36Cl ion energy of 64, 49 and 33MeV, respectively. 36Cl and 36S particles were successfully separated in the TOF spectra output from the GF-TOF detector. The comparison between the gas-filled time-of-flight method and the ΔE-E method is described. Some results relative to the GF-TOF method are given as well.
