【Abstract】 Successive approximation approach was used to simulate the characteristics of the time of flight (TOF) of charged particles in a planar curvilinear system of the uniform sector magnetic analyzer.The electron trajectory expression in the sector magnetic analyzer up to 2nd order was derived and the 1st order and 2nd order transfer coefficients of the TOF were also obtained.The transfer coefficients of TOF properties can also be calculated in terms of the corresponding image spatial transfer coefficients.更多还原
