Abstract :
The 750-keV radio-frequency quadrupole (RFQ) accelerator section is under development. It will be installed upstream of the first drift tube cavity of the MMF linac instead of a two-gap buncher. Using the RFQ will allow decreasing the accelerating tube voltage to 400 kV and increasing pulse duration two times without pulsed transformer saturation. The RFQ section has a high capture efficiency (up to 67%), a length of 1.3 m, and beam bunching without a longitudinal halo.<>
