description: This work is devoted to modeling and verification of operation in various modes in order to optimize a time-of-flight mass analyzer based on a wedge-shaped field, time-of-flight mass analyzers are one of the most common types of mass analyzers. For these purposes, the Simion 3D 7.0 and COMSOL Multiphysics applications were used. The model of the device was designed, the main operation modes were modelled and the main parameters were calculated, the last affect the accuracy and sensitivity of the analyzer. Numerical experiments were carried out, which showed that the wedge-shaped mass analyzer has high accuracy in analyzed ion mass definition and sensitivity with the right choice of its parameters. The developed model can be used to design and optimize wedge-shaped mass analyzers in various fields of science and technology.
