The methodology for low energy spread RFQ beam dynamics design has been studied for 14C+ AMS application. This paper will present a low energy beam dynamics and rf design for a new trapezoidal IH-RFQ. It will accelerate 14C from 40 keV to 500 keV with the length of 1.1 m; operate at 104 MHz with the rf peak power less than 27 kW. The transmission efficiency is better than 95% and the energy spread is as low as 0.6%. The rf structure design and its rf efficiency have been studied by electromagnetic simulation. It shows such trapezoidal IH-RFQ has higher operating frequency than normal IH-RFQ, and it will have more longitudinal accelerating efficiency.
