A double-frequency ECR ion source has been modelled numerically for high-efficiency ion production from protons to uranium.

MOPRI082	Acceleration of High-Intensity Heavy-Ion Beams at RIKEN RI Beam Factory	ion, ion-source, cyclotron, linac	800

	Recent efforts concerning the RIBF accelerators in RIKEN have been directed towards achieving higher beam intensities of very heavy ions such as uranium and xenon. As presented in the last IPAC conference in 2013, the intensities of these ion beams have significantly improved due to the construction of a new injector, RILAC2, which is equipped with a 28-GHz superconducting ECR ion source, the development of a helium gas stripper, and upgrading of the bending power of the fRC. In this light, this paper presents the subsequent upgrade programs carried out in the last couple of years, such as developments of a new air stripper for xenon beams and a micro-oven for metallic ions. The current performance level of the RIBF accelerator complex, as well as a future plan to further increase the beam intensities, are also presented.

WEPRO083	Implementation of a Superconducting Electron Beam Ion Source into the HIT Ion Source Test Bench	ion, rfq, ion-source, emittance	2153
	E. Ritter, A. Silze, G.H. Zschornack DREEBIT GmbH, Dresden, Germany R. Cee, Th. Haberer, A. Peters, T.W. Winkelmann HIT, Heidelberg, Germany G. Zschornack TU Dresden, Dresden, Germany
	Cancer therapy with light heavy ions is now a well proven technology. Almost all facilities are running Electron Cyclotron Resonance Ion Sources (ECRIS) to produce carbon ions and protons as well. In the 1990’s the idea of using a Electron Beam Ion Source was proposed (EBIS) [1]. Some proof of principle measurements were carried out [2] but the application of EBIS ion sources in radiation facilities has not been established. We present results from the implementation of a superconducting EBIS, the Dresden EBIS-SC, at an RFQ accelerator at the testbench of the Heidelberg Ion Therapy Center (HIT). First results from C 4+ ions produced by the Dresden EBIS-SC [3] and injection in an RFQ accelerator at the HIT testbench are shown. Furthermore, emittance measurements as well as investigations of the ion energy and the transmission through the RFQ were done. The emittance of the EBIS source is lower by a factor of nine compared to an ECRIS, which improves the transmission through the RFQ. With the current setup the ion output from the EBIS-SC is lower by a factor of 7 compared to an ECRIS to fulfill the requirements of the highest irradiation level. Further improvements are discussed. * erik.ritter@dreebit.com
