For heavy-ion cancer therapy with carbon, there is a problem about radiation exposure due to secondary particles produced by heavy ion incident reaction. We have a plan to extend our improved intra nuclear cascade (INC) model for proton incidences to INC model for alpha and carbon incidences. However, there is no experimental data about multi-particle (proton, deuteron, triton, He and alpha) production double differential cross sections (DDXs) for alpha incident reactions to validate the extended INC model. In this work, we measured multi-particle production DDXs for 100 and 230 MeV/nucleon alpha incident reactions on samples (C, Al, Co, Nb) at the HIMAC building in National Institute of Radiological Sciences (NIRS), QST. As a result, we found that results calculated by the extended INC model agreed with experimental data at 30 degrees and those underestimated the experimental data with increasing angles.
