New organizational structures for the Single-phase ProtoDUNE are in place for managing the construction, installation, commissioning, and operation of the detector in a test beam at CERN in 2018. These new structures, coordinated by the DUNE Technical Board, draw from the Far Detector teams and the already established ProtoDUNE-SP team — and nailing down all the roles has taken a lot of thought and discussion. To get this detector online in the short timescale available, it is important that the collaboration understand how the process will work.
Since ProtoDUNE-SP will be constructed from prototype full-scale components for the first 10-kt far detector, the DUNE far detector organization is responsible for the design and fabrication of the major detector components for the prototype. However, in order to assemble these components into a working experiment, a second, parallel organization is needed to manage activities on the ground at CERN.
A strong leadership team is in place for the CERN activities. Flavio Cavanna and Christos Touraminos will serve as the coordinators ProtoDUNE-SP, with Thomas Kutter as deputy coordinator. Maria Chamizo Llatas will serve as the manager. In this role she will direct the day-to-day activities at CERN, and provide the interface to the CERN Neutrino Platform, which provides both the supporting infrastructure for the detector and the test beam. As deputy coordinator, Kutter will assist the coordinators and direct physics studies and simulation efforts that define the experiment’s measurement program.
Three types of structures will support this team.
First, a Detector Integration, Testing, and Installation group, headed by Chamizo Llatas, is responsible for carrying out all of the on-site activities at CERN. The group (necessarily) includes detector experts from the far detector organization. They will spend extended periods at CERN, and in this role, will report to the ProtoDUNE-SP management team.
Second, working groups responsible for the production (as well as the integration, testing, installation, and operation) of detector components specific to the ProtoDUNE-SP detector will need to form. Unlike the DUNE far detector, of course, this detector will be operated at CERN in a beamline on the surface. It will therefore need a slow controls system compatible with the CERN infrastructure, beam monitoring equipment, and potentially a cosmic ray tagging system, among other possible items. Since many of these items are also needed for the dual-phase ProtoDUNE, some or all of these working groups will straddle the single- and dual-phase organizations.
Third, the experimental physics program will form a working group to define the proposed measurement programs. It will also set up small teams to interface with the DUNE Computing and Software organization on topics such as event reconstruction and offline processing.
Within the DUNE collaboration structure, the far detector and ProtoDUNE-SP detector organizations are parallel to one another (along with the near detector and ProtoDUNE-DP organizations) directly under the Technical Board. This body, which includes the management teams of each detector organization, is charged with reaching consensus on technical decisions and passing recommendations to the DUNE Executive Committee for final approval. In addition to discussing key issues for the ProtoDUNE-SP effort, the TB reviews proposals from institutions wishing to contribute to various detector construction efforts to ensure that sufficient resources are provided for both fabrication and installation/commissioning activities.
The ProtoDUNE-SP organization has a lot to do on a tight timescale. The new structure is already helping the activities move forward, thanks to the strong initial efforts of the new management team.
