The de­sign progress of the Radio Fre­quen­cy Quadrupole (RFQ) ac­cel­er­a­tor for the Com­pact Pulsed Hadron Source (CPHS) at Ts­inghua Uni­ver­si­ty is pre­sent­ed in this paper. The RFQ will ac­cel­er­ate pro­tons from 50 keV to 3 MeV, with the RF fre­quen­cy of 325 MHz. The ob­jec­tive is to ob­tain the op­ti­mum struc­ture of the RFQ ac­cel­er­a­tor with high trans­mis­sion rate and tol­er­a­ble total length. The beam dy­nam­ics are stud­ied by the sim­u­la­tion of the pro­ton beam in the RFQ ac­cel­er­a­tor with the code of PARMTE­QM. The out­put pro­ton beam from the RFQ is well matched into the DTL with­out Medi­um-En­er­gy-Beam-Trans­port (MEBT) be­tween the RFQ and DTL.
