1. Muon g-2 Muon g-2 Experiment Quarterly Report Aria Soha All Experimenter’s Meeting March 2, 2015

2. Vacuum Progress Since Oct 6 th (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 2

3. Magnet Progress Since Oct 6 th (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 3

4. Electrical Progress Since Oct 6 th (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 4

5. Instrumentation Progress Since Oct 6 th (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 5

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 6
