RadiaBeam, in collaboration with Argonne National Laboratory, are developing an ultra-high gradient linear accelerator, Advanced Compact Carbon Ion Linac (ACCIL), for the delivery of ion-beams with end-energies up to 450 MeV/u for 12C⁶⁺ ions and 250 MeV for protons.

In this paper we will compare these types of accelerating structures in terms of RF, beam dynamics and thermo-mechanical performance.

The design of RF structure of them is based on the J-PARC linac. After the first demonstration of neutron production on December 2015, significant modifications to the linac were given in order to increase the operation stability and the beam power.

	CERN has built a compact 750 MHz RFQ as an injector for a hadron therapy linac. This RFQ was designed to accelerate protons to an energy of 5 MeV within only 2 m length. It is divided into four segments and equipped with 32 tuners in total. The RFQ length corresponds to 5λ which is considered to be close to the limit for simple field adjustment using tuners. Nevertheless the high frequency results in a sensitive structure and requires careful tuning by means of the alignment of the pumping ports and fixed tuners. This paper gives an overview of the tuning procedure and bead pull measurements of the RFQ.

The carbon beam energy can be adjusted from pulse to pulse, making 3D tumor scanning straightforward and fast.
