Abstract
The requirements for the geometrical dimensions and ion packet deflection angles to achieve a maximum resolution of the mass-reflection with a field-free gap introduced between its decelerating and reflecting gaps are considered. The results obtained demonstrate the capability of the device proposed to make TOF analysis of the ion packets with large ion energy spread. It is also shown that, if by some reasons, the energy range of the ions entering the routine reflection can be predetermined, the regime with slightly detuned deceleration voltage is preferable, as it provides better mass resolution.
