Abstract
| In the Linac 4 and the SPL a 3 MeV RFQ is required to accelerate the H- beam from the ion source to the DTL input energy. The IPHI RFQ, primarily designed for high beam power applications, is presently being built within a collaboration between CEA, IN2P3 and CERN and is intended to become the front end for the new CERN accelerator complex. However, a new shorter RFQ optimised for the CERN lower duty application would present several advantages with respect to the IPHI one. The design of such an RFQ is the subject of this note. |
