The invention relates to the field of technology of heavy-ion beam cancer therapy, in particular to a Bragg curve detector and a using method thereof. A Bragg curve detector for quick measurement in heavy-ion cancer therapy comprises an outer frame (1) and a plurality of unit ionization chambers (2), and is mainly characterized in that: water equivalent bodies (3) with different thicknesses are arranged in front of the unit ionization chambers (2); an incidence window (1-1) and an emergence window (1-5) are arranged at front and rear ends of the outer frame (1); a supporting plate (1-2) with a groove, a signal lead-out plate (1-3) and a high-voltage input plate (1-4) are arranged between the incidence window (1-1) and the emergence window (1-5); each unit ionization chamber (2) comprises a signal pole (2-1) which is connected with the signal lead-out plate (1-3) and a high-voltage plate (2-2) which is connected with the high-voltage input plate (1-4); and the unit ionization chambers (2) and the water equival
