  12. Schedule/Responsibilities • A prerequisite for major diagnostic design effort is the renegotiation of the PP’s to resolve existing scope ambiguities and clarify stakeholder roles/responsibilities and permitting detailed design to begin. • In the present plan, most procurements would be made during the fabrication phase from FY10 - FY12. • As partner lab responsible for diagnostics, PPPL will subcontract with other experienced institutions to provide the instruments. • PPPL will design the port plugs, will integrate the ‘front-ends’ from multiple systems, and will oversee the fabrication, assembly and testing of the plugs.
