The work of the Diagnostics Working Group successfully completed

The ITER diagnostic system comprises about 45 individual measurement systems involving a very wide range of technologies (magnetics, neutron systems, optical systems, microwave systems etc). It is a distributed system with components installed in the vacuum vessel, the divertor, the ports (23 at all three levels in total), the port cells, the tokamak building and in the diagnostics building. It will play an important role in the operation of ITER and the scientific programme. It is expected that all ITER Parties will contribute to the supply of the diagnostics, but a new method for the procurement of the systems is being considered. In July 2003, the Participant Team Leaders and the International Team Leader approved a task to develop the approach to diagnostic procurement. Specific recommendations have been made for the future stages in the preparation of the ITER diagnostic system and the ITER IT and PTs will carry these forward
