The status of RF components on Maria Filippova, RF components: Loads Phase shifters Attenuators Hybrids Splitters Directional couplers WR 90 (E/H) bends RF flanges (SLAC design) RF flanges (CERN design) Gaskets The aim of the meeting is to give the status of the current production.

Status of RF components on RF components have to be supplied to the following projects: -X-Band stand alone test -TBL series (for TBL prototype RF com. are supplied) -TBTS phase 2.2 (for phase 1 and 2.1 RF com. are supplied) -PSI (CH) -Trieste/ Elettra (IT) -RF components for KEK and Klystron test at SLAC are already supplied. We have got the full information of the RF components needed to supply by CERN for these projects on the 13 th of February The total information is presented in summary table in two parts. The 1 st part of the summary table shows the information about following RF components: loads, phase shifters, attenuators, hybrids, splitters, directional couplers, WR 90, RF flanges (SLAC design) male/female, RF flanges (SLAC design) closed male/female, RF flanges (CERN design), gaskets.

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.

Status of RF components on Maria Filippova, 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.

Status of RF components on Maria Filippova, 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 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.

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 Maria Filippova,
