Vacuum Progress Since Oct 6th (Last Quarter)

• Found “Short” on Lead Can• Cryo Platform installed with Dewer• ALL Cryostat Insulating Vacuum is Leak Check Certified!• Pressure tested Nitrogen & Helium Circuits • Removed AD Cryo Test Box (Frig check out complete)• Indium Resistance Measurements (Bolts tightened)• “Cold Leak” Found: Electrical Isolators on Interconnects

replaced – Leak Checked OK– Isolators on Lean Can (6) Inspected, – Will be replaced when parts arrive– Isolators on hairpin not accessible

Magnet Progress Since Oct 6th (Last Quarter)

• Installed Top Yoke! – All Yoke Vertically & Radially aligned– Horizontal ear shims installed, but bolts are still loose (pole

alignment)– Steel “make-up” plates installed

• All 3 Cryostats Shimmed, Vertically & Radially aligned, and bolted & pinned in place– Support of Inner Upper coil transferred to upper yoke– Jack bolts removed from Outer Coil– Push Rods installed– Transport radial stops replaced – All strain gauges repaired or documented

• Poles are clean! – Ready to Install

Electrical Progress Since Oct 6th (Last Quarter)

• Waterfall support structure & cable tray Installed• Ring Cable Tray Installed• Dump resistor mounted on roof (cables go outside)• Bruckner PS fully checked out & Installed in Hall

– Connected to building Power

• Dump Trip Cabinet Installed & connected to PS• Quench Protection Rack rebuilt & Installed in Hall• Electrical Grounding Infrastructure mostly in place

5

Instrumentation Progress Since Oct 6th (Last Quarter)

• LCW Systems and Instrumentation Installed• Controls cabinets in Computer Room being filled• Built & Routing cables for

– Ring Instrumentation – LCW Instrumentation

• ODH System Operational

6

The MC-1 Building

• Door Locks / Card readers installation

• Need Training to enter• Mezzanine has a

Source box• All Phones installed

– Ctrl Rm = xMuon

• Internet in MC-1

• G-2 Hall is Now ODH Ø– No additional training is

necessary– If alarms go off, Leave.

• If using a ladder on Cryo platform use fall

protection tie-offs
