A solid detector for intermediate energy protons needs a thick material to stop incident protons. The response function of detector has a full-energy peak and a tail when monochromatic energy protons are measured by the detector. A tail subtraction technique with particle identification was applied to remove the tail. The Gaussian distribution was fitted to a peak in a particle identification spectrum. In this technique, the window of three times of standard deviation in the peak region was found to be proper in anayzing the particle identification spectrum. Using this technique, the tail could be removed. The peak efficiencies of the stacked spectrometer for protons were obtained up to 250MeV.
