The problems of matching the initial parameters of analyzed ions with the parameters of periodic orbits of charged particles in RF ion traps with discrete planar electrodes used as detectors of induced currents in mass spectrometers with Fourier transform are considered. The aim is the development of mode and input device of charged particles in RF ion trap Monotrap. It is shown that to implement uniform field ion mode the input voltage is required to be changed exponentially.
The parameters of exponential voltage during inout are defined. Computer simulation of the process of ion trap entering the radio frequency Monotrap is given. The estimates of mass range in mass - spectra with Fourier transform, using ion trap ions as a detector of radio frequency are obtained.
Key words: RF ion trap, mass analyzer with Fourier transform, discrete planar electrodes, ion input system.
