This study aims to accurately measure the beam quality of carbon ions using a microdosimeter in carbon ion therapy. In the MCA currently used to measure the energy spectrum according to the magnitude of the measured pulse signal, it has been confirmed that the signal in the low energy region is unstable, so we try to directly acquire the pulse and directly process the signal without using the MCA. This work will include filtering accompanied by noise rejection using Fourier transforms for signal processing. Through securing a more accurate energy spectrum, we intend to contribute to the treatment of cancer patients by more accurately measuring the quality of the beam of carbon ion therapy.
