Status and First Measurement Results for a High Gradient CH- Cavity — •Ali Almomani and Ulrich Ratzinger — Institut für Angewandte Physik - Frankfurt Universität, Frankfurt am Main, Germany

This pulsed linac activity aims on compact designs and on a considerable increase of the voltage gain per meter. A high gradient CH * cavity operated at 325 MHz was developed at IAP * Frankfurt. The mean effective accelerating field for this cavity is expected well above 10 MV/m at β = 0.164. This cavity is developed within a funded project. The results might influence the rebuilt of the UNILAC * Alvarez section, aiming to achieve the beam intensities specified for the GSI * FAIR project (15 mA U28+). Another motivation is the development of an efficient pulsed ion accelerator for significantly higher energies like 60 AMeV. The new GSI 3 MW Thales klystron test stand will be used for the cavity RF power tests. Detailed studies on two different types of copper plating will be performed with this cavity.
