For the LINAC of the Munich accelerator for fission fragments (MAFF) an IH-RFQ resonator is under construction. This resonator will operate at a resonance frequency of 101.28 MHz, which is the upper frequency limit for those structures and with a maximum duty cycle of 10%. The MAFF IH-RFQ will accelerate ions with A/q < 6.5 from 3 keV/u injection energy to about 300 keV/u. Intensive simulations with MWS and PARMTEQ have been performed to reach a final design for the resonator. A short model has been built and low level r.f. measurements are in progress to test the calculations. The mechanical design has been confirmed and the full power cavity will soon be ordered. The injection scheme for MAFF has been modified to allow the installation of a low frequency multi-harmonics buncher allowing thus more time separation between main bunches. A new layout of the accelerator facility will be presented.
