CCDTL (F. Gerigk)

• First 2 CCDTL cavites arrived at CERN, preparations in progress. From the CERN side we will need to prepare:
  • assembly procedure ready by 15.9 (Benoit), t.b.c.
  • laser tracker ready on 2.10, various survey measurements during the visit (Jean-Frederic), ok
  • vacuum equipment (pump, RGA) ready on 1.10 (Jan), ok
  • vacuum connection pieces (2x half-cell, 6x beam pipe), instrument-cross exists, (Jean-Michel, Yves) under construction
  • minimum vacuum support during their stay (Jan), ok
  • SM18 test stand ready for high-power tests from 15.10 onwards (Jose), in prepration.
  • water hoses and connectors ready on 1.10 (Jean-Michel), ordered
  • nuts and bolts and tools ready on 1.10 (Jean-Michel), nuts and bolts ok, tools waiting,
  • Helicoflex joints ready on 1.10, (Jean-Michel), ok
  • pre-assembly table ready on 1.10 (Yves, Jean-Michel)
  • re-machining of assembly table (Jean-Michel, Yves), under construction
  • visa invitation Alexandr, (Frank), ok
  • subsistence + travel costs Alexandr (Frank), ok
  • GSM for Alexey (Frank), requested
  • admin, office, transport, etc, (Frank), t.b.c.
  • visual inspection of half tank gaskets at Alexandre Gerardin (Jean-Michel), in progress
  • lifting arm will be put into the assembly area (chèvre) to be able to move tanks on the support but not to lift them (Jean-Michel, Yves), ok,
  • put some cabinets into the assembly area for material storage (Jean-Michel, Yves), ok,
  • provide blocks onto which the support frames can be put (Jean-Michel, Yves), in progress
  • prepare coupler with movable tuner for measurements (Jean-Michel, Rolf), ok, PIMS coupler works for CCDTL, piston tuner in bunker and movable short in assembly area,
  • are the counter olives for the welded SERTO fittings delivered by Alexey (Frank),

DTL (S. Ramberger)

• Segment T1S1 has been assembled with 16 of the 22 drift tubes. The last missing drift tube, number 122 is currently being assembled in the central workshops followed by the last 8 drift tubes of T3.
• The last pieces of the production of drift tube parts, three modified stems for repairs, are on the way to CERN. All stems in the last delivery that were reported out of tolerance by DMP have been found to be in tolerances. An order for spare material has been cancelled.
• CADINOX has supplied a planning for the segment manufacturing after the stop for the water channel repair, with the following dates:
  • T1S2 11/2012
  • T3S1/T3S4 12/2012
  • T3S2/T3S3 01/2013
  • T2S1/T2S4 03/2013
  • T2S2/T2S3 03/2013

SM18 – Linac4 test stand (R. Wegner)

• A high power test of the 1st PIMS cavity with beam instrumentation is foreseen for next Wednesday, goals: 1. monitoring signals from the installed beam instrumentation (BPM, FCWT) and 2. monitoring breakdown signals. Can we use the installed beam instrumentation for detecting dark current and breakdowns or shall we look for other instrumentation as a faraday cup?
