	The accelerators of the Facility for Antiproton and Ion Research – FAIR are under construction. The sophisticated system of accelerators is designed to produce stable and secondary beams with a significant variety of intensities and beam energies. FAIR will explore the intensity frontier of heavy ion accelerators and the beams for the experiments will have highest beam quality for cutting edge physics to be conducted. The main driver accelerator of FAIR will be the SIS100 synchrotron. In order to produce the intense rare isotope beams (RIB) at FAIR, a unique superconducting fragment separator is under construction. A system of storage rings will collect and cool secondary particles from the FAIR. Intense work on test infrastructure for the huge number of superconducting magnets of the FAIR machines is ongoing at GSI and several partner labs. In addition, the GSI accelerator facility is being prepared to serve as injector for the FAIR accelerators. As the construction of the FAIR accelerators and the procurement has started, an overview of the designs, procurements plans and infrastructure preparation can be provided.

WEPMA022	Progress of the Klystron and Cavity Test Stand for the FAIR Proton Linac	2802
	A. Schnase, E. Plechov, J. Salvatore, G. Schreiber, W. Vinzenz GSI, Darmstadt, Germany C. Joly, J. Lesrel IPN, Orsay, France
	In collaboration between the FAIR project, GSI, and CNRS, the IPNO lab provided the high power RF components for a cavity and klystron test stand. For initial operation of the 3 MW Thales TH2181 klystron at 325.224 MHz we received a high voltage modulator from CERN Linac 4 as a loan. Here we report, how we integrated the combination of klystron, high voltage modulator, and auxiliaries to accumulate operating experience. RF operation of the klystron started on a water cooled load, soon the circulator will be included and then the prototype CH cavity in the radiation shielded area will be powered. The 45 kW amplifiers for the 3 buncher structures of the FAIR proton Linac were checked at the test stand, and the results are presented here.

THPF011	Status of the FAIR Proton Linac	3702

	For the research program with cooled antiprotons at FAIR a dedicated 70 MeV, 70 mA proton injector is required. The main acceleration of this room temperature linac will be provided by six CH cavities operated at 325 MHz. Within the last years, the assembly and tuning of the first power prototype was finished. The cavity was tested with a preliminary aluminum drift tube structure, which was used for precise frequency and field tuning. Afterwards, the final drift tube structure has been welded inside the main tanks and the galvanic copper plating has taken place at GSI workshops. This paper will report on the recent advances with the prototype as well as on the current status of the overall p-Linac project.

THPF013	UNILAC Proton Injector Operation for FAIR	3709

	The pbar physics program at the Facility for Antiproton and Ion Research (FAIR) requires a high number of cooled pbars per hour. The FAIR proton injector with coupled CH-cavities will provide for a high intensity (35 mA) pulsed 70 MeV proton beam at a repetition rate of 4 Hz. The recent heavy ion UNIversal Linear Accelerator (UNILAC) at GSI is able to deliver proton as well as heavy ion beams for injection into the FAIR-synchrotrons. Recently GSI UNILAC could provide for a two orders of magnitude higher proton beam current in routine operation. A hydrocarbon beam (CH3) from the MUCIS ion source was accelerated inside High Current Injector and cracked in a supersonic nitrogen gas jet into stripped protons and carbon ions. A new proton beam intensities record (3 mA) could be achieved during machine experiments in October 2014. Potentially up to 25% of the FAIR proton beam performance is achievable at a maximum UNILAC beam energy of 20 MeV and a repetition rate of 4 Hz. The UNILAC can be used as a high performance proton injector for initial FAIR-commissioning and as a redundant option for the first FAIR-experiments.

THPF014	325 MHz High Power RF Coupler for the CH-Cavities of the FAIR p-LINAC	3712
	F. Maimone, R. M. Brodhage, M. Kaiser, W. Vinzenz, M. Vossberg GSI, Darmstadt, Germany
	In order to supply the input RF power to the Cross-bar H-mode (CH) cavities of the p-LINAC for FAIR an inductive RF coupler has been studied. The designed RF coupler, and its water cooled inductive loop, has to withstand up to a 3 MW pulsed power (at 325 MHz). At GSI a prototype has been manufactured and tests were performed. The prototype of the designed high power RF coupler is presented together with the results of the coupling measurements at the CH-prototype cavity.

	M. Vossberg, R. M. Brodhage, M. Kaiser, F. Maimone, W. Vinzenz, S. Yaramyshev GSI, Darmstadt, Germany
	The planned 27 m long Proton-Linac (P-LINAC) for FAIR (Facility for Antiproton and Ion Research) comprises a RFQ (Radio-Frequency Quadrupole) and 6 CH-cavities to accelerate a 70 mA proton beam up to 70 MeV. The FAIR Proton-Linac starts with a 325.2 MHz, from 95keV to 3 MeV RFQ accelerator. The main RFQ for this Proton-Linac will be a 4-Vane RFQ. RF analytics with varying and constant transverse focusing strengt for the electrode parameters will be used. CST simulations will help to find cavity parameters for the working frequency. This paper presents the main cavity designs concepts and CST simulation results.
