摘要：
A time-of-flight mass spectrometer comprises: an ionization unit for receiving an electron beam and emitting ions; a cold electron supply unit for injecting an electron beam into the ionization unit; an ion detection unit for detecting ions discharged from the ionization unit; and an ion separation unit for connecting the ionization unit and the ion detection unit, wherein the cold electron supply unit comprises a microchannel plate, which receives ultraviolet rays and emits an electron beam, ions discharged from the ionization unit pass through the ion separation unit and reach the ion detection unit, and the ion separation unit has the shape of a straight tube.
