LBNF LongBaseline Neutrino Facility Neutrino Beamline Modules Preliminary
LBNF Long-Baseline Neutrino Facility Neutrino Beamline Modules Preliminary Design Review Introduction Keith Gollwitzer 13 August 2020
Review Plan • Two half days – afternoons - Agenda on Indico • Projects->LBNF->Beamline Reviews • Review Committee is encouraged to ask questions anytime • After most technical talks there is 15 minutes for discussion • Entire review is being done via Zoom - Please turn off video to save bandwidth • Seems to be a problem when have more than half a dozen connected - Please keep muted when you are not talking 2 8. 13. 20 Keith Gollwitzer | Introduction LBNF
Introductions • Review Committee - Ang Lee (PPD/Mechanical Engineering Department) - Rob Ridgeway (AD/Mechanical Support Department) - Ryan Schultz (Oak Ridge National Lab/Spallation Neutron Source) • Presenters - Cory Crowley - Mike Campbell - Meredith Lee - Nnamdi Agbo 3 8. 13. 20 Keith Gollwitzer | Introduction LBNF
DUNE & LBNF The Deep Underground Neutrino Experiment will be a world-leading experiment for neutrino science, potentially transforming our understanding of why the universe exists as it does. The Long-Baseline Neutrino Facility is the infrastructure necessary to send a powerful beam of neutrinos 800 miles through the earth and measure them deep underground at South Dakota’s Sanford Underground Research Facility. DUNE/LBNF project will be the first internationally conceived, constructed, and operated megascience project hosted by the DOE in the U. S. 4 8. 13. 20 Keith Gollwitzer | Introduction LBNF

Charge -- 1 of 2 1. Does the preliminary design meet the requirements and requirements of the Beamline? a. 1. Does the anticipated design life meet experimental requirements of 30 years of operation prior to failure? Is the design maturity presented for the Modules, stripline shield blocks, interfaces, and ancillary systems at a level appropriate for the Preliminary Design Phase, as guided by EDMS # 2173197 LBNF / DUNE Review Plan? a. b. c. Based on acceptable progress for Preliminary Design as 50 to 70%, with 100% means being ready for procurement. Are areas where components are awaiting forthcoming development well understood? Final Design will be drawing-intensive in comparison to the first two phases of design. 2. Have suitable engineering analyses been performed and documented, and reviewed/peer reviewed and approved, where applicable? 3. Are the appropriate codes and standards adequately applied to the design? 4. Have the Fermilab Engineering Manual standards been applied to the design? 5. Have ES&H issues been identified analyzed appropriately? 11 8. 13. 20 Keith Gollwitzer | Introduction LBNF
Charge -- 2 of 2 7. Have potential design, manufacturing, and installation risks and challenges been identified within the Modules WBS, and has it been adequately planned to address these during the final design? 8. Are difficult design features and possible prototyping issues identified? 9. Is the level of integration with other LBNF beamline entities appropriate for this stage of the work? I. E. Are interfaces and collaborative design inputs being managed appropriately? a. A major Horn A Module system interface is the integrated target, which is being designed and built by RAL. Have all integration activities pertaining to the mating of these components been identified? b. Are there any outstanding design considerations for the integrated target utilities which have not been identified by the design teams? 10. Select Module components have undergone estimation review through a Project Estimator. A cursory check of the cost and schedule are desired: 12 a. To verify top level cost estimates for fabrication & testing. b. To question sufficiency of design resources with known complexity of certain features, such as stripline shield blocks, drive systems, and Non-DOE interfaces 8. 13. 20 Keith Gollwitzer | Introduction LBNF
