TUPAB147	The Final RF-Design of the 36 MHz-HSI-RFQ-Upgrade at GSI	1678
	M. Baschke, H. Podlech IAP, Frankfurt am Main, Germany L. Groening, S. Mickat, C. Zhang GSI, Darmstadt, Germany
	In Darmstadt/Germany the existing accelerator cite GSI is expanding to one of the biggest joint research projects worldwide: FAIR, a new antiproton and ion research facility with so far unmatched intensities and quality. The existing accelerators will be used as pre-accelerators and therefor need to be upgraded to fulfill the requirements with respect for intensity and beam quality. In a first step the 9.2 m long 36 MHz-HSI-RFQ for high current beams will obtain new electrodes to reach the specific frequency and to allow a higher electric strength. Therefor several simulations with CST MWS have been done. The final RF-design will be presented.

TUPVA057	Design Study for a Prototype Alvarez-Cavity for the Upgraded Unilac	2205
	M. Heilmann, X. Du, P. Gerhard, L. Groening, M. Kaiser, S. Mickat, A. Rubin GSI, Darmstadt, Germany A. Seibel IAP, Frankfurt am Main, Germany
	The design study describes the prototype Alvarez-tank of the new post-stripper of the UNILAC. A prototype with 17 drift tubes (including quadrupole singulets) of 3 m of total length and 2 m of diameter will be manufactured. This cavity features new drift tube shape profiles to provide for high shunt impedance at a maximum electric surface field of 1 Ek. Additionally, it allows realization and high power testing of an optimized stem configuration for field stabilization. In case of successful tuning and long-term operation at high power level, it shall be used as a first of series cavity of the new UNILAC post-stripper DTL.

THPVA003	Status of the Beam Dynamics Design of the New Post-Stripper DTL for GSI-FAIR	4414
	A. Rubin, X. Du, L. Groening, M. Kaiser, S. Mickat GSI, Darmstadt, Germany
	The GSI UNILAC has served as injector for all ion species since 40 years. Its 10⁸ MHz Alvarez DTL providing acceleration from 1.4 MeV/u to 11.4 MeV/u has suffered from material fatigue and has to be replaced by a new section. The design of the new post-stripper DTL is now under development in GSI. Five Alvarez tanks with four intertank sections provide 100% transmission and low emittance growth. The intertank sections allow for a matched solution and provide place for diagnostics. Simulations along the complete Alvarez DTL were done for 238U²⁸⁺ using the TraceWin code. The transversal zero current phase advance is 65' for all tanks. Results of beam dynamics simulations for six different scenarios as well as an error study for the FAIR nominal case are presented.
