By the end of the 2017, we wish to converge on the conceptual design that the DUNE collaboration intends to take forward. This workshop is part of this process. A number of options will be considered, the existing FGT design, a LAr-TPC, a system based around a High-Pressure Gaseous Argon TPC tracker and a hybrid option. The meeting will focus on the merits of the different options. We will also touch on the possible funding sources for various options. The meeting is open to existing DUNE collaborators and any potential new collaborators with an interest in participating in the design, planning and construction of the DUNE near detector system.
