1. Team meeting – accelerating structure production G. Riddone, AB-RF 2008.01.09

2. Saclay – HDS thick, 30HDSQtk.Cu Cleaning CW29 Heat treatment and HPR test at Saclay – HDS11, 50 CW30 Heat treatment done in CW31 Shipped to Saclay in CW33 HPR test made CW35 Decision to replace it during shut-down (problem with leaktightness of helicoflex joints)  new joints sent to CEA Discovered problem on cover plate  remachining done and sent back to Saclay Assembly made at Saclay BUT Meeting at CERN on 04.12  actions defined for burr removal and rf check calibration 4 windows: CW2 Then send to Sacley with screws and helicoflex joints IMTEC - Cu HDS11 small, 30HDSQ11S.Cu Received at CERN in CW44 RF check in CW45 (they are OK) Metrology: CW51 OK Cleaning: CW02 SEM: CW03 Heat treatment: CW04 Structures under preparation

3. Other structures • HDS11 small Mo  in the lab, should be heated up (6 h before putting it in vacuum), • HDS11 small Ti  in the lab, dimensional control OK, • Pulse heating cavity  at Gonzalo’s office for SEM (action Samuli) • W 2p/3 clamped  in the lab

4. Megich, Cu circular thin, 30CNSQth.Cu  arrived at CERN in CW42, 08.10.2007 RF checks in CW42  report in EDMS Dimensional control  CW43 (iris too thin 55 micro) Cleaning cw45 SEM cw45 Tuning: tests under way in b169 (machining “spherical milling”) metrologic results (matching irisx2)  CW49 Ask for 2nd structure if firm understands the reason of the error  prototype quadrant has been checked at Megich  good results Metrology of this quadrant before starting tuning of the structure 30HDStk.Cu#2 (P1 for next test): RF checks CW41 Microscopic inspections CW42 (damages not visible) SEM CW44 Burr removal: CW47 Chemical treatment SUBU: CW47 SEM: CW51 (EDMS notification received) Heat treatment: CW03 SEM: CW03 Structures under preparation

5. Structures under fabrication • Cu circular thin, 30CNSQth.Cu#2, Megic • 1 new quadrant (no news) • Old test pieces will have to be sent to CERN • Waiting for CERN payment • Clic vg1 quadrant damped, 11WDSQvg1Cu.1, VDL • 3 quadrant ready, 1 quadrant under fabrication • Cu quadrant 2p/3, 30CNSQ2p3.Cu, Micron-Cluny • Tool characterization under way • Slot for machining: CW50 (CERN visit to M-C), no tuning holes • Dimensional control CW51 • Ready for shipment CW02 (accepted delivery w/o holes) • 30HDSr1.2.Cu • 1 ordered at UNITEK: ready for shipment: mid of January 2008 • 1 ordered at VDL: ready for shipment: feb 2008 • 30CNSDSB.Cu • 1 ordered at VDL
