	In order to have an inexpensive alternative to 4-Vane RFQs above 200 MHz, we study the possibilities of a Ladder-RFQ. The 325 MHz RFQ is designed to accelerate protons from 95 keV to 3.0 MeV according to the design parameters of the research program with cooled antiprotons at FAIR. This particular high frequency for an RFQ creates difficulties, which are challenging in developing a cavity, especially for 4-ROD RFQs, which dimensions become critically small with increasing the frequency. In order to define a satisfying geometrical configuration for this resonator, both from the RF and the mechanical point of view, different designs have been examined and compared. Very promising results were reached with a ladder type RFQ, which has been investigated since 2013. Due to its geometry, the manufacturing in terms of complexity, time and costs is more beneficial compared to welded accelerators. Furthermore, maintenance is easy to handle. The manufacturing, coppering and assembling of a 0.8 m prototype RFQ is finished. We present recent measurements of the RF-field including power measurements, frequency-tuning, field flatness as well as power measurements.

In order to have an inexpensive alternative to 4-Vane RFQs above 200 MHz, we study the possibilities of a Ladder-RFQ. The 325 MHz RFQ is designed to accelerate protons from 95 keV to 3.0 MeV according to the design parameters of the research program with cooled antiprotons at FAIR. This particular high frequency for an RFQ creates difficulties, which are challenging in developing a cavity, especially for 4-ROD RFQs, which dimensions become critically small with increasing the frequency. In order to define a satisfying geometrical configuration for this resonator, both from the RF and the mechanical point of view, different designs have been examined and compared. Very promising results were reached with a ladder type RFQ, which has been investigated since 2013. Due to its geometry, the manufacturing in terms of complexity, time and costs is more beneficial compared to welded accelerators. Furthermore, maintenance is easy to handle. The manufacturing, coppering and assembling of a 0.8 m prototype RFQ is finished. We present recent measurements of the RF-field including power measurements, frequency-tuning, field flatness as well as power measurements.
