LBNF/DUNE update: a really good week

On (last) Tuesday morning, an important addendum to the Neutrino Protocol between the United States and CERN was signed after many months of hard work by the DOE Office of High Energy Physics and CERN. This addendum lays out the framework and objectives for CERN’s participation in the U.S. neutrino program, including the Short-Baseline Program and LBNF…

“On track for CD-2” says U.S. DOE review committee

A unique and interesting aspect of LBNF/DUNE is that it represents both a facility built under U.S. DOE procedures with significant international support, and an international experiment with a DOE contribution. From the DOE perspective, LBNF and DUNE-U.S. are one project, and the project requires annual reviews. The 2017 review took place at Fermilab from February 28th to March 2nd…

Integration and safety for far site facilities, cryo and detector

During the week of 5 December, CERN hosted a series of meetings to discuss integration between the LBNF far site conventional facilities and the massive cryostat for the first DUNE neutrino detector. Immediately following, the Fermilab cryogenics safety panels for LBNF and SBN held extensive discussions with CERN engineers…

CD-3a achieved: Green light from DOE for construction work at SURF

On September 1st the Department of Energy formally approved plans for construction of the first two large underground caverns at Sanford Lab for the Deep Underground Neutrino Experiment. This milestone, known as “CD-3a approval,” represents DOE’s green light to begin the significant amount of conventional facilities work at Sanford Lab necessary to support the DUNE experiment…

Beamline alternatives ruled out

Visualization of the focusing system chosen by the optimization using a NuMI-style target (top), a Beryllium fin target (middle) and a cylindrical target (bottom).

To reach its ambitious physics goals, DUNE wants a neutrino beamline delivering neutrinos to the far detector by 2026. Over the last few months, many members of DUNE/LBNF have reviewed and evaluated the baseline beamline design as well as an innovative, alternative approach called Neutrinos from PIon beam Line, or NuPIL, in order to determine the best path forward…

International standards and the U.S. DOE

DUNE/LBNF has been an international project from the start. As such it presents differences from typical DOE-funded projects in many areas. We are evolving approaches to developing systems and procedures that will allow us to move forward in this international environment, and have completed an extensive amount of work in the codes and standards domain…

SURF tour impresses DOE VIP

On July 5th, Under Secretary Franklin Orr visited Sanford Lab in Lead, SD to visit the proposed site of the LBNF far site facilities and tour the laboratory’s 4850L…  His visit, for which he skipped a day of his family vacation in South Dakota, demonstrated his interest in this project, and it offered an excellent opportunity for an in-depth show-and-tell…
