Analysis of Gas-Filled Time-of-Flight Detection Method

The paper concerns in the principle and the experimental results of gas－filled timeofflight (GF－TOF) detector. ³⁶Cl and ³⁶S particles were successfully separated in the TOF spectra from the GF－TOF detector for the ion with the energy of 64, 48 and 33 MeV, respectively. The comparison of the separation power of isobars between the GF－TOF method and the ΔE－E method was carried out. The experimental results indicate that the separation power of the ΔE－E method is better than that of the GF－TOF method at the energy larger than 40 MeV, and the GF－TOF method is better than the ΔE－E method at the energy less than 40 MeV, especially at the energy range of 20－40 MeV.
