This LAr1 Prototype review will examine the status of the 1 kilton prototype (LAr1) planned for the LBNE LAr Subproject, and its role in assuring readiness of the LAr technology within the LBNE Project timeframe. The LAr1 project will be evaluated against CD-1 level requirements, appropriately applied given its status as a sub-project of the larger LBNE Project. This review is called by and reports to the LBNE Project Manager.
