LBNF

Near-term status of LBNC Milestones


• Updates since May 2017 DUNE collaboration meeting:

- CM/GC contract award 9 August 2017

- Ross Shaft: work crew shift schedule changed in early August to allow

work to reduce workers safety concerns, will complete slightly later

without impact to future activities

- Main excavation final design delayed due to final contractual details

LBNF

Reliability Project – Ross Shaft Renovation

Work has progressed to 4,772 level (95% complete)


• Ross Shaft constructed in

1930s. Legacy shaft

infrastructure cannot support

the structural loads and duty

cycle needed for LBNF, thus

rehabilitation was initiated in

2012 to modernize the shaft.

• Work is very close to the

bottom of the shaft – gets

more complicated as it

approaches bottom opening

and below the 4850L

• Extending completion due to

change in crew schedules

LBNF

Other Reliability Projects near-term


• Ground Support – East/West Access

- Ground support deteriorated due to age and

flooding of the mine after shutdown.

- West and East Lab Access drifts will be

completely bolted to provide safe passage for

utilities and logistics.

• Oro Hondo Fan replacement

- Main exhaust fan – variable frequency drive

obsolete and starting to be problematic

- If fails, shuts down diesel equipment

underground

• Hoist Clutches & Brakes and Variable

Speed Drives

- Replace 1930’s technology that doesn’t meet

code and risks shaft operation and potentially

personnel safety

- Improve energy efficiency

Status:

• Underway

• Complete Dec 17

Status:

• Working to

accelerate

replacement plan to

ASAP

Status:

• In planning

• Start Jan 18

• Phased thru Feb 19

LBNF

FSCF Pre-excavation Construction Status


• Construction to start by CM/GC in early 2018 (pending DOE appropriation)

- Underground rock handling (ore passes, skip loading, temporary grizzly, rock spill collection system)

- Rock crushing system

- Installing surface pipe conveyor to open cut

- Ross headframe reinforcement

- Shaft utilities: fiber optic and power cables, water and gas piping

- Electrical service on the surface to the shaft

• Surface rock conveyor ordered June 2017 -should be ready for installation late summer 2018

LBNF

Final FSCF Design for Excavation & Building/Site

Infrastructure


• Final design has two scope elements: main excavation (EXC),

and buildings/site infrastructure (BSI)

- Deliverables planned at 30%, 60%, 90%, and 100% of final design

• FD and cryo will participate in weekly design meetings with A/E

• Provides defined points for stakeholder review

• CM/GC provides independent cost/schedule estimates & constructability

reviews

- Design is under configuration control; all proposed changes are

evaluated for cost and schedule impact

LBNF

Cryogenic Systems Design Status


• LN2 system: working on solicitation for design-fab-install

contract for this system

• Proximity Cryogenics on the mezzanine and LAr/GAr purification

system in Central Utility Cavern:

- Joint effort of Fermilab and CERN (Proxy cryo on mezzanine only).

- Developing work packages and understanding how to engage

possible partners.

LBNF

• LBNF and DUNE have worked to better define penetrations needed for

FD and cryogenic systems

• Third evolution of CERN design for the steel structure design of cryostat

#1 accommodates single-phase detector penetrations

• CERN working to initiate design contract with membrane cryostat

designer, GTT, by early 2018

Cryostat Design Status


• LBNF is holding

independent design

review of steel structure

next week at SURF

LBNF

Beamline/NSCF Status


- Requires 4 (vs. 2) interaction length target and 3 (vs. 2) magnetic horns.

- Collaborating with RAL on the conceptual design of the optimized target

and its mounting in the first horn.

- LBNF is holding Beam Optimization Review to evaluate the conceptual

design, cost, and schedule on 5-6 October.

- EFIG will discuss incorporation of this design into the LBNF/DUNE plan

soon thereafter.

- Decision process described in DocDB 1900.

• Optimizing target and

focusing horns for better

sensitivity to CP

violation.

LBNF

Beamline/NSCF Status


• Collaboration with IHEP/China:

- Testing prototype corrector magnet from IHEP at Fermilab

- Discussing additional collaboration on other beamline systems, e.g.

decay pipe beam window

• Collaboration with KEK – interested in supporting beamline,

discussions underway

LBNF is very interested in engaging with all partners who

might be interested in participating in design and

construction of the beam.

Please contact Elaine McCluskey and/or Vaia Papadimitriou.

LBNF Project Reviews and Advisory Boards


• DOE Reviews

• Independent progress reviews (IPR) required by DOE project management process

✓ February 2017 – IPR focused on entire Project (LBNF+DUNE-US)

• Next DOE IPR likely in Feb 2018

• Long-Baseline Neutrino Committee (LBNC) Reviews

- Weekly conferences with Chair, Laboratory, LBNF, and DUNE leadership.

- Multi-day reviews nominally three times/year. In 2017

✓ 23 – 26 March at Fermilab

✓ 22 – 26 June at CERN

• 26 – 29 October at SURF

• LBNF Strategic Project Advisory Committee (SPAC)

- Provides independent advice on issues and strategies related to project organization, management, and risks; engagement with international institutions, and project execution.

✓ February 2017 – focused on start of construction at Far Site

• Fall 2017 meeting is in planning

LBNF

LBNF Staffing Updates since May 2017 collaboration meeting


• New people

- As the protoDUNEs are installed, Jack Fowler is transitioning to

become the LBNF/DUNE Systems Engineer

- Cryo-mechanical engineer hired in August

• Recruiting in progress

- Far Site Logistics Manager position – candidate interview

evaluations in progress

• Hiring planned for next 18 months

- Three field construction coordinators for LBNF construction work at

Sanford Lab

- Two additional procurement administrators for LBNF contracts

LBNF

Summary


• Groundbreaking held at Far Site

• Far Site CM/GC contract awarded

• Beginning final design for CF

• Planning for construction activity to ramp up with pre-exavation

activities underway early 2018

• Continuing to add staff to ensure ability to execute

• Continuing outreach for nonDOE participation across LBNF

• Working funding profile closely with DOE to continue outyear

funding ramp up to continue timely construction progress
