Wolfgang Vinzenz FAIR Proton Linac 10 th FAIR MAC November 25 th and 26 th 2013 Proton Linac 6 Comment from MAC May 2013 to the RFQ :...Clear steps forward on these issues should be taken within the next 6 months, else they would probably enter the critical path of the FAIR schedule. RFQ RFQ Meeting took place 20 th and 21 st of November 2013 Invited participants from CERN3 IAP Frankfurt3 AVS Huelva1 FAIR1 GSI8

Wolfgang Vinzenz FAIR Proton Linac 10 th FAIR MAC November 25 th and 26 th 2013 Proton Linac 7 Some remarks to the meeting CERN could clearly show the excellent performance of the LINAC4 RFQ. This result could be reached due to the challenging selection of materials, the well planned steps in manufacturing and the brilliant collaboration with all those involved. IAP presented new fabrication methods (massive Cu block) to avoid alignment errors and contact problems. The always possible access in case of repair was pointed out. A 4-rod at 325 MHz with the 4-vane precision can be performed. 2 nd IAP presentation showed the layout of a Ladder-type 4-rod. A crankshaft-type fixation of the rods guaranties the alignment precision. Those rings used at the 36 MHz IH-type RFQ at GSI. The RF part of the cavity is made from two massive Cu blocks. RFQ
