Title – xxxx 9 Preliminary US-HiLumi Magnet Scope MQXFA LMQXFA (Q1) LMQXFB (Q3) Five Q1 Cold Masses (LMQXFA) and Five Q3 Cold Masses (LMQXFB) —Each cold mass includes two ~ 4.8m Nb3Sn magnets (MQXFA) installed in a SS helium vessel with end domes, ready for insertion into a cryostat by CERN —Option: deliver magnets (MQXFA) after vertical test

Title – xxxx 10 US-HiLumi Magnets Timeline Tentative plan: —Assumes Q1 and Q3 tunnel installation in CY-2024 —Provides 3.5 years for CERN Q1 and Q3 scope (cryostating, test, etc) —Production Coil winding must start in January 2018 (US Critical Decision 3 DOE approval, CD-3) —Two years of preparations needed for strand and series production tooling procurements, start cable fabrication, etc. —Production throughput based on June 2013 MQXF fabrication plan

Title – xxxx 11 US-HiLumi Preliminary Top Level Schedule Assumes Q1 and Q3 tunnel installation in CY2024 First LMQXFA/B cold mass delivered to CERN summer 2020 Last LMQXFA/B cold mass for tunnel installation delivered to CERN summer 2022 Last LMQXFA/B cold mass spare delivered to CERN summer 2023

Title – xxxx 12 Preliminary Fabrication Plan Plan is based on the production plan presented by M. Anerella during the June 2013 DOE review of LARP plus additional information Nb 3 Sn: — First strand delivery one year after placing purchase order. Last delivery 2 years later. A total of 9,400 Kg will be needed for 90 coils Cable and Insulation (LBNL): — Starts three months after first strand delivery — Throughput starts at 2 UL/month, ramping to a peak rate of 3 UL/month — A total of 90 ULs are needed for 90 coils — Insulation by vendor — Total duration ~ 3 years CERN is back-up for cabling, and LARP is for CERN

Title – xxxx 13 Preliminary Fabrication Plan (Cont.) Coil Fabrication: — Two production lines (FNAL and BNL) — Peak rate: 1 coil every 15 working days First two coils in each facility assumed to take twice as long First 4 coils: 8 months after coil production starts — Total duration for 90 coils ~ 3.5 years — Additional tooling needed at each production line to sustain throughput: One additional winding mandrel assembly Two additional reaction fixtures One additional impregnation fixture Looking at optimizing parts procurement between LARP & CERN

Title – xxxx 14 Preliminary Fabrication Plan (Cont.) Magnet Assembly (LBNL): — Starts ~ 8 months after coil fabrication starts As soon as a set of four coils are delivered — Includes Yoke/Shell structure assembly, coil pack insert assembly, and magnet assembly — Two production lines. In each line, peak rate: 1 coil pack insert every 60 working days 1 yoke/shell assembly every 75 working days (concurrent) 1 magnet assembly every 34 working days — Peak overall rate: 1 magnet every ~ 2.2 months First magnet assumed to take twice as long — Total duration for 20 magnets is ~ 4 years

Magnet Test (BNL): — Test and train each magnet in BNL vertical test stand prior to cold mass assembly Needed quantity under consideration It takes ~ 38 working days for a production vertical test Cold Mass Assembly (FNAL): — Connection of two magnets, installation of stainless steel skin and end domes, heat exchanger, bore tube, etc. — Peak rate: 1 cold mass every ~2 months First assembly assumed to take 3 months Cold Mass Test (FNAL): — Insert cold mass in re-usable cryostat and test cold mass in Fermilab’s Horizontal test stand — Peak rate 1 cold mass test every ~3.5 months First test assumed to take 1.5 times longer, second test 1.25 times longer Assumes no prior magnet training Assumes 30 training quenches per magnet

Title – xxxx 16 US-HiLumi Early Milestones Frozen Baseline: — Definitive scope — Detailed resource loaded schedule — Time-phased budget — EVMS-ready Baseline must be frozen before March 2016 Earned Value Management System (EVMS) monthly reporting is required six months prior to the independent Director’s CD-2 review, which is required before a DOE CD-2 review EVMS requires a frozen baseline –Changes after baseline freezing require going through a change control and approval process –Monthly Cost/Schedule variances must be explained and corrective actions put in place
