This report updates the VTS group on the progress and preparations for the cryostat fabrication at PHPK, Columbus, OH, as of November 2, 2006. Key points include the status of change orders, instrumentation supplied by Fermilab, and ongoing biweekly conference calls. We highlight the advanced design and costing of radiation shielding, RF system components, and safety planning. Safety measures like electrical, general, and cryo-mechanical protocols are in progress, ensuring documentation will be ready one month prior to expected operation.

Vertical Test Stand Update C.M. Ginsburg (Fermilab) For the VTS group: C.Sylvester, Y.Huang, R.Nehring, J.Ozelis, T.Peterson, V.Poloubotko, R.Rabehl, I.Rakhno, C.Reid, M.Wong 02.November.2006
VTS Cryostat • Preparations for fabrication underway at PHPK (Columbus, OH) • Biweekly phone conferences • 3 change orders by end of this week (2nd top plate, holes in top plate, attaching ring segments) • Fermilab supplied instrumentation on its way • Valves from Cryolab (Leslie Controls, Inc.) are 2 months late; so far not affecting schedule • We are impressed by PHPK’s commitment to keeping schedule, and working with us to fulfill requirements • Magnetic shielding purchase requisition by the end of this week C.M.Ginsburg ILC/SRF 05.Nov.06
More VTS progress • Radiation Shielding (Igor, Valeri) • Shielding design update by Igor for updated (realistic) geometry; technical memo update soon • Shielding lid layout and movement by Valeri well advanced; beginning costing • RF System (Joe, Roger) • Assembly and in-house fabrication underway and on schedule • All components including racks have arrived except vector modulator (ok) • 500W CW amplifier specs to be measured by John Reid • MFR Ophir: performs better than specs • Cryo system tie-in has begun (Yuenian, Charlie Hess) • Variable coupler design (Andrei Lunin) and thermometry system design (Aseet Mukherjee) underway for beyond-the-baseline C.M.Ginsburg ILC/SRF 05.Nov.06
Planning for operation (ORC) • Electrical Safety (Jim Garvey) • General Safety (Rich Ruthe) • Cryo-mechanical Safety (Bill Soyars (AD)) • Engineering documentation to be available one month before desired operation • FMEA, What-if analysis underway (Mayling) • Radiation Safety (Kamran Vaziri (ES&H)) • Kamran is up to speed on expected radiation and shielding design - so far so good • RF personnel safety interlocks design by Chuck Worel (AD) and Joe submitted to Kamran Oct. 27 • Plan for location of area radiation monitors and operational procedures with Sue McGimpsey (ES&H, Acting Radiation Safety Officer for VTS) underway C.M.Ginsburg ILC/SRF 05.Nov.06
