Deliverables • Finish fabrication of 7 remaining solenoids. • Finish fabrication of sub-systems: – Couplers. – Tuners. – BPMs. • Engineering cooldown of cryostat vessel to 80 K. • Finish RF surface processing of 7 production HWRs. • Cold testing of 7 production HWRs. 2 Conway | 2016 P 2 MAC 3/15/2016

Solenoids • All 8 units are finished. • Does FNAL want to test one

Solenoids • All 8 units are finished. • Does FNAL want to test one prior to 30 September 2016? • Ready for installation into the cryomodule. • Need the remainder for the mock-assembly which is starting in the next 2 -3 weeks. 3 Conway | 2016 P 2 MAC 3/15/2016

Sub Systems • Tuners = finished. • BPMs = finished (17 May 2016). •

Sub Systems • Tuners = finished. • BPMs = finished (17 May 2016). • Couplers: working on thermal transitions. The cold and warm windows are in-hand. Testing remains to be done on all components. Finished BPM and Beam Line Spool Assembly 4 Conway | 2016 P 2 MAC 3/15/2016

Engineering Cool Down Alignment Target Shift Due To Pump Out • The cryomodule with the titanium strong back were cooled to 80 K. • Cryomodule thermal load: – To 80 K = 110 W. – Expected = 160 W. • Strong back did not distort during thermal cycling. No need for thermal stress relief. 6 Target Shift Due To Cool Down

Finish Processing on all 7 HWRs Frame (HWR 3 in Background) • 4 HWRs

Finish Processing on all 7 HWRs Frame (HWR 3 in Background) • 4 HWRs = Finished. • 3 HWRs need the 625 C hydrogen degassing and light polish. • Cavities and frame ready to proceed with 6250 C hydrogen degassing. 7
