Abstract：
Beam dynamics design of an RFQ with low energy spread is introduced. The energy spread of the output ¹⁴C beam is about 0.6%, which shows the feasibility to use RFQ in the AMS facility instead of tandem accelerators. The RFQ is also compact with low power dissipation. The isotopes ¹⁴C, ¹³C and ¹²C can be fully separated in the RFQ, so the AMS background could be reduced and the whole system may be simple.
