We have been developing a downsized accelerator mass spectrometer dedicated to carbon-14 using a surface stripper. In order to demonstrate the practical application of ¹⁴C measurement, we have performed surface scattering experiments using KCl crystals; C^- was obliquely incident on the KCl crystals, and the rate of charge conversion of specularly reflected particles was calculated. In addition, we adjusted the beam of positive ions after charge conversion, detected dissociated fragments downstream of the analyzing magnet, and confirmed the operation of the ion detector with proportional counters.
