  1. ILCTA_MDB HTS Update Andy Hocker 31-AUG-2006

  2. Cryostat arrived at MDB 12-JUL A. Hocker, ILCTA Meeting

  3. Since then… • Cryostat leak-checked by TD T&I mechanical techs • Cryostat support frame moved into cave • Needed fixes identified • New rupture disc • Heat leak • Cryostat safety document written • LL dewar design sent to MS for fabrication 4 K 2 K 4 K A. Hocker, ILCTA Meeting

  4. To do • Install/leak check new rupture disc • Install insulating shims around pipes • Install/leak check LL dewar and piping • Dummy load for commissioning • Move cryostat into MDB cave • Problem: nobody available in TD to do this for ~3 weeks • T&I mechanical group are swamped with magnet work • Not likely to provide any continued support • So, what to do? • AD will be working on instrumentation infrastructure in meantime A. Hocker, ILCTA Meeting

  5. Milestones • 20-SEP: All parts in hand/tech help available • 29-SEP: Cryostat work finished • 6-OCT: Cryostat installed in MDB cave and connected to feedbox • 13-OCT: Safety review • 20-OCT: Dummy load cooled to 1.8 K Ready to accept a cavity A. Hocker, ILCTA Meeting

  6. Misc. • 3 dressed cavities from DESY to arrive in ~3 weeks? • We get one • Will need an engineering document, I’m told • AD guys were procuring cavity/coupler clean vacuum carts --- need to follow up • Good progress at CC2 reading out coupler data via EPICS, using it to control synthesizer • First step in automation (and datalogging) A. Hocker, ILCTA Meeting

  7. HTS has an e-log Get a password from Michele McCusker (mccusker@fnal.gov) E-log tutorial from Suzanne Gysin today at 15:30, here A. Hocker, ILCTA Meeting
