  1. Update of First Mirror Table Presented by T. Sugie A. Costley (ITERO) A. Litnovsky (FZ Juelich, Germany) and Participant Teams 12th Meeting of the ITPA Topical Group on Diagnostics 26 – 30 March 2007, PPPL. Princeton USA

  2. Introduction 10a225: Costley/Sugie/Litnovsky to coordinate the update of the mirror table. A mirror map was presented by Sugie. Still to be expanded with further information: angle of incidence, etc. In cooperation with each party, • Table of ITER diagnostic first mirrors is updated. • The updating work is under progress. • The maps of the first mirror positions and the lines of sight, which were updated from June 2006 to March 2007, are made as an one of the basic data for first mirror works.

  3. Coordinates of mirror center and line of sight (1) z Mirror LOS O a Mirror LOS Port-2 R q Port-1 Fig. 2 Plan view of mirror position and the line of sight R: distance from the torus center q: toroidal angle of mirror position a: angle of line of sight (on the horizontal plane) Fig. 1 Elevation view of mirrors and each main line of sight Ex. Center line of port-1: q = 10 Center line of port-2: q = 30
