Three main problems were observed at the existing RFQ: A strong thermal sensitivity, modulated reflected power, and insufficient stability of the contact springs connecting the stems with the tuning plates. Although the last problem was easily solved, the first two remained and greatly hindered operations. To resolve this issue and ensure stable injection into the HLI, a new RFQ-prototype, optimized in terms of vibration suppression and cooling efficiency, was designed at the Institute of Applied Physics (IAP) of Goethe University Frankfurt. To test the performance of this prototype, high power tests with more than 25 kW/m were performed at GSI. During those, it was possible to demonstrate operational stability in terms of thermal load and mechanical vibrations, calculating the thermal detuning, and proof the reliability of the proposed design.
