A com­pact dual-gap Multi-Har­mon­ics Buncher has been suc­cess­fully used at the SSC-Linac, a lin­ear ac­cel­er­a­tor ded­i­cates to beam in­jec­tion into SSC in HIRFL. SSC-Linac op­er­ates at 53.667MHz, which is forth time of the RF fre­quency of the SSC. In order to in­crease the lon­gi­tu­di­nal cap­ture ef­fi­ciency, and en­hance the cur­rent out of SSC, an in­de­pen­dent MHB(Multi-Har­mon­ics Buncher) had been in­stalled into the LEBT of SSC-Linac. The fun­da­men­tal fre­quency of the MHB is 13.417MHz. The buncher adopts the me­chan­i­cal struc­ture of dual-gap and saw­tooth wave­form is gen­er­ated by multi-har­mon­ics syn­thetic tech­nol­ogy. Beam per­for­mance sim­u­la­tion with MHB have been done with code BEAM­PATH. Be­sides, 84Kr14+ beam has been bunched suc­cess­fully using the MHB in our ex­per­i­ments, the max­i­mum bunch ef­fi­ciency of 86.1% has been mea­sured in ex­per­i­ments.
