These components will be delivered ready to be installed (i.e. with flanges already brazed) by CERN to PSI (CH) and Triesta (IT). CERN asked about machining and brazing of the straight WR90 waveguides and of the bends (E-type and H-type) VDL. The part of the ordered waveguide flanges can be used by VDL for fabrication of these items. This can be launched soon.

8. Status of RF components on 20.04.2010 Maria Filippova, 20.04.2010 Photo 1. H-bend bending test and cut/ throughPhoto 2. Front view of bend cut/ through With the material CERN have supplied VDL did several tests to see if they can manufacture the bended pipes. The results are shown on the photos 1,2. There is a small distortion only on the outside as a result of material displacement. (This inside is filled with a kind of water-dissolvable wax to prevent inside distortion.) CERN cannot make a decision about acceptable result based on the photos. The bends shall be sent to CERN for inspection and validation in few days.

9. Status of RF components on 20.04.2010 Maria Filippova, 20.04.2010 Notes: PSI (CH): - Straight raw waveguide, RF flanges and gaskets have high priority and should be sent as soon as possible. The rest of the components shall be delivered as soon as they are available, in any case it would be preferable to have all the items for September 2010. Trieste (IT): -To be sure that the WR circuit will fit the klystron position. Trieste ask that the exact length of the two WR90 straight pieces, marked WR90 S1416 FxM and WR90 S687.5 FxF, would be communicated later. -Trieste prefer to have a cooling system brazed on the WR90, but the layout is not yet decided. -solution with WR 90, no ceramic window, no vacuum valve adopted.

10. Under discussion : Q (Trieste): Could CERN provide us as a Magic Tee to split the power before the section? A (CERN): We can send our splitters. Is it fine with you? If not, we cannot to supply The Magic Tee. Conclusions: New components have to be ordered: one directional coupler (to be confirmed) WR90 flanges H/E bends Status of RF components on 20.04.2010 Maria Filippova, 20.04.2010
