A 3.115m long, 324MHz, 3MeV radio-frequency quadrupole (RFQ) linac is used as the first RF accelerator of the J-PARC linac. We have performed RFQ simulations to provide a particle distribution for an end-to-end (from the RFQ entrance to the injection point of the rapid cycling synchrotron (RCS)) simulation of the J-PARC linac. Two simulation codes, PARMTEQM and TOUTATIS are used for the RFQ simulations. The simulated emittances show good agreements with the ones measured at the exit of the medium energy beam transport (MEBT).
