	Low velocity particles are critical in every hadron accelerator chain. While RFQs nicely cover the first MeV/u range, providing both acceleration and bunching, energies higher than few MeV/u require different structures, depending on the specific application. In the framework of the TULIP project [1], a 750 MHz IH structure was designed, in order to cover the 5-10 MeV/u range. The relatively high operating frequency and small bore aperture radius led the choice towards TE mode structures over more classic DTLs. Hereafter, the RF regular cell and end cell optimization is presented. An innovative solution to compensate dipole kicks is discussed, together with the beam dynamics and the matching with the 5 MeV 750 MHz CERN RFQ [2]. This structure was specifically designed for medical applications with a duty cycle of about 1 ', but can easily adapted to duty cycles up to 5 %, typical of PET isotopes production in hospitals.

Low velocity particles are critical in every hadron accelerator chain. While RFQs nicely cover the first MeV/u range, providing both acceleration and bunching, energies higher than few MeV/u require different structures, depending on the specific application. In the framework of the TULIP project [1], a 750 MHz IH structure was designed, in order to cover the 5-10 MeV/u range. The relatively high operating frequency and small bore aperture radius led the choice towards TE mode structures over more classic DTLs. Hereafter, the RF regular cell and end cell optimization is presented. An innovative solution to compensate dipole kicks is discussed, together with the beam dynamics and the matching with the 5 MeV 750 MHz CERN RFQ [2]. This structure was specifically designed for medical applications with a duty cycle of about 1 ', but can easily adapted to duty cycles up to 5 %, typical of PET isotopes production in hospitals.
