We present the demonstration of digital rectilinear ion trap (RIT) mass spectrometer. We designed and manufactured the RIT based on the design of Ouyang et al. For the operation of this mass analyzer, we applied concepts of the digital ion trap, in which RF voltages of the rectangular waveform was applied to the electrode, not typical sign waveform. Besides, the mass scan is also done by frequency scan, not by voltage scan. In this research, we used the FPGA controller for the generation and control of the rectangular waveform. Circuits composed of two high power/RF MOSFETs were also made to generate trapping voltages. All I/O communication was controlled by home-built LabVIEW software. We plan to conduct the performance experiment of this mass spectrometry in detail and expand it for more sophisticated analyses.
