Title:     New Developments for RFQ Accelerators and CH-Cavities

Abstract: RFQ accelerators are the standard devices for bunching, focusing and acceleration of hadron beams at low energies. While for protons mostly 4-Vane RFQs at higher frequencies are used, the 4-Rod Structure is the common structure for heavier ions. During the last years a program has been initiated to overcome some of the disadvantages of 4-Rod RFQs as an intrinsic dipole component and limiting cooling capabilities for high power operation. 
CH-cavities belong to the family of H-mode cavities using the H211-mode. In general, they have high shunt impedance and can be operated at higher frequencies compared to IH-cavities. Due to the mechanical rigidity CH-cavities can be realized for room temperature and superconducting operation. During the last years several CH-cavities have been developed and tested with high gradients up to 14 MV/m. In 2017 the first beam test of a superconducting CH-cavity has been performed successfully.    


Stimulants available 15 minutes before the talk.
