Guidance from the LBNC

compass-freeThe Long-Baseline Neutrino Committee (LBNC) conducted a comprehensive face-to-face review of DUNE and LBNF at Fermilab in mid-June, the first of its kind since last January at the collaboration meeting in Dallas.

The LBNC, appointed by the Fermilab director and occupying an “advisory” box on the high-level DUNE/LBNF organization chart, is charged with providing regular peer reviews of the scientific, technical and managerial aspects of the program, for both the collaboration and the projects.

At the June review, the committee was asked to review progress on previous recommendations and, in particular, to make a close examination of the ProtoDUNE-SP and ProtoDUNE-DP efforts.

The LBNC appreciated the progress being made by the collaboration task forces, while expressing concern about potential shortfalls in resources. In addition to manpower, it recommended bolstering project management tools to incorporate more detailed milestones into the schedule and expanding the ProtoDUNE-SP and -DP risk registers.

The electronics noise observed in the recently completed 35-ton prototype run received some focused attention. The committee was generally supportive of the plan that DUNE laid out for attacking this issue, yet also recommended a number of steps for boosting the resources assigned to the cold electronics development program. Integration testing of the updated cold electronics design is a major focus over the next several months. All parties share the goal of achieving improved electronics performance for ProtoDUNE-SP.

Across the DUNE/LBNF program, the findings and recommendations confirm that the current efforts are aimed in the right areas and that the LBNC recognizes the challenges faced by the project and collaboration. The committee wants to stay informed through well-documented key milestones and get more people involved in several technical areas.

“The LBNC is working effectively to provide effective advice and guidance to LBNF/DUNE,” said Mark Thomson. “They recognized the positive progress we’ve made on development of a sound strategy for the ProtoDUNEs and CD-2/3, and made a number of constructive suggestions to address potential concerns.”
