While many international high power accelerator projects have successfully controlled transverse beam emittance growth in RFQs, longitudinal beam emittance remains significant and can negatively impact beam transmission in the downstream accelerating structures, particularly in super-conducting sections. This study focuses on beam dynamics design for a 100 mA proton RFQ linac. The dynamic parameters of the RFQ are well adjusted with particular attention paid to both transverse and longitudinal beam dynamics to control the emittacne growth. Beam dynamics simulations were performed using the codes TRACEWIN and TOUTATIS. The analysis of reasons for emittance growth and RFQ beam losses are performed, and the results of error studies of the RFQ are presented. ER -
