Accelerator Mass Spectrometry (AMS) is presently the most sensitive technique for the measurement of the actinides, particularly for the measurement of ²³⁶U. A Time of Flight-Energy (TOF-E) detection system is the most appropriate technique to discriminate ²³⁶U ions from ²³⁸U, ²³⁵U and other interferences. Before the construction of actual TOF-E system, a SRIM (The Stop and Range of Ions in Matter) simulation of time resolution and ion transmission of TOF-E system has been simulated. The simulation results have shown that adopting the configuration of 8.9 ug/cm² carbon foil and one Microchannel Plate (MCP) is adequate to identify ²³⁶U and its interferences.
