USIPO will not be able to place large design contracts until ambiguities are better resolved.

Oversight and coordination Scope Packages inclu ‘front-end’ viewing de optics, relayoptics or waveguides in the ports, along with additional relay systems to bri g signals to diagnostic n hall, and source and detector hardware in the diagnostic hall. Some have viewing systems in ports provided by other parties. Package includes oversight of testing on ports prior to shipment to ITER Requirements not well defined 3 ITPA12 Diagnostics - PPPL - 3/26-30/07 Diagnostic Front-End Integration • Design constraints – Intermingling of numerous labyrinths, many with precision optics – Provide access while limiting neutron streaming – Provide attachments and cooling to blanket shield modules • Plug E3 is a US responsibility (DWG Sharing Agreement) – Many other diagnostics need to be integrated into plug E3  > 2 visible/IR camera views (EU)  2 edge CXRS views (RF)  2 H arrays (RF)  X-ray crystal views (possible) (??) • The division of integration design responsibility between the IT and the parties has not been fully negotiated. 4 ITPA12 Diagnostics - PPPL - 3/26-30/07 Development of Radial Diagnostic Cassettes • Radial cassettes may make integration and testing easier. • May also make maintenance easier. 5 ITPA12 Diagnostics - PPPL - 3/26-30/07 Central Tube Development for Upper Ports • Metal seal, removable back plate gives access to central tubes. • Back plate has only windows. “Hard” feedthrus on side panels 6 ITPA12 Diagnostics - PPPL - 3/26-30/07 Developing Neutronics Capability with ATILLA Tetrahedral Mesh - 496k Cells • ATILLA, a discrete-ordinates, radiation transport code produced by Transpire, Inc., is being benchmarked for use on ITER. • In the US, this work is a joint PPPL/UCLA effort well connected to IO and EU efforts. (See Talk by R. Feder later today) • Potentially essential tool for qualifying diagnostic labyrinth designs. 7 ITPA12 Diagnostics - PPPL - 3/26-30/07 Assessment Studies • For the US instrument development, near-term priorities were • • • • • presented to the community and widely distributed last Spring. Priorities stressed better definition of instrument front-end configurations, performance assessments, consideration of alternate approaches and tool development. ~ 40 discussions with experts concerning these priority issues and relevant capabilities were documented. Awards for a total of 14 studies (including 2 cost studies) were made in summer and fall. Results will be presented at this meeting. All studies are completed or nearing completion  75% of reports have been submitted. Final reports will be placed on ITER IDM system. • 8 ITPA12 Diagnostics - PPPL - 3/26-30/07 Assessment Studies Diagnostic Package Upper Visible/IR Camera MSE MSE MSE LFS Reflectometer ECE ECE Divertor Interferometer RGA Tang.

Definition of mutually agreeable integration of front-end components within the plugs will facilitate many parallel detailed design efforts. FY2014 delivery of qualified port plugs is consistent with top level IO schedule – Detailed plan will likely feature plug delivery phased over a multi-year period. 11 ITPA12 Diagnostics - PPPL - 3/26-30/07
