Measurement Requirements and the Diagnostic System on ITER : Modifications Following the Design Review .

The requirements for plasma and first wall measurements on ITER, and the planned ITER diagnostic system, have been reviewed as part of the ITER design review process by a panel of experts experienced in operating modern tokamaks. The review panel recommended some changes in both the measurement requirements and the diagnostic system. These changes have been largely adopted and a new baseline diagnostic system has been developed. In this paper we present the main changes and outline the new baseline diagnostic system.
