Adapted from the Fermilab article of 4 June 2018 DUNE collaboration grows to 32 countries, prepares for operations of prototype detectors.
During the collaboration meeting at Fermilab from May 14-18, the DUNE Institutional Board admitted two new institutions to the collaboration: the Laboratory of Instrumentation and Experimental Particle Physics, which is the first institution from Portugal to join DUNE, and the University of Bucharest, the second institution from Romania. The collaboration now comprises 1,061 scientists from 175 institutions in 32 countries.
A substantial portion of the collaboration meeting was devoted to the upcoming operation of two DUNE prototype detectors at the European research center CERN, known as ProtoDUNEs, with speakers presenting the updates on the construction happening this spring.
“There has been really remarkable progress,” said DUNE co-spokesperson Ed Blucher, professor at the University of Chicago. “Congratulations to the installation teams at CERN for their incredible efforts on the two ProtoDUNE detectors. Both are on track to collect data that will be important for finalizing the specifications of the liquid-argon detectors for the DUNE experiment.”
Filling of the first prototype detector at CERN with liquid argon, known as the single-phase ProtoDUNE detector, is anticipated to begin in July or August.
“Completion of the huge ProtoDUNE detector in little over two years is an extraordinary achievement by groups on both sides of the Atlantic,” said ProtoDUNE co-leader Christos Touramanis, professor at the University of Liverpool in the UK. “It fills us with confidence that the ambitious DUNE construction schedule will be met.”
The construction of the second prototype detector at CERN, known as the dual-phase ProtoDUNE detector, also is progressing well. The installation of the detector will be completed in fall of this year.
“The innovative design of this prototype is the outcome of a long R&D process, “said CNRS Research DIrector Dario Autiero of the French National Institute of Nuclear and Particle Physics. “The construction effort for this large-scale detector required a strong dedication from many groups and would not have been possible without the fundamental support from CERN.”
Another important topic at the collaboration meeting was the Interim Design Report (previously called the Technical Proposal) for the construction of DUNE far detector modules in South Dakota. The document is based on the experience DUNE scientists and engineers gained during the design and construction of the prototype detectors at CERN. It is a step toward the publication of the more detailed Technical Design Report in 2019, which will serve as the blueprint for the construction of the first DUNE far detector modules.
“Within a few months, the recently formed DUNE Far Detector Institutional Consortia were able to provide detailed documentation on the current state of their planning efforts,” said Eric James, DUNE technical coordinator. “Production of the Interim Design Report on such a short time scale sends a strong signal that the collaboration remains on track to meet its goal of producing the Technical Design Report for the first two far detector modules by spring 2019.”
