Tokamak Fusion Test Reactor: A Diagnostics Perspective

摘要

The purpose of this report is to provide DOE with succinct descriptions of many of the diagnostics units, emphasizing their role in the overall experimental program. This approach, while introducing a degree of redundancy, serves to illustrate how specific measurements are to be made during various phases of operation. In this manner the vital role of diagnostics in magnetic fusion research becomes more evident. Section I will present those diagnostics that will be essential in analyzing the plasma during the optimization phase of operation. Section II discusses the diagnostics that are planned for the D-D Q=1 equivalent phase of operation and some of the difficult measurements that will have to be made in order to interpret the beam-beam, beam-target and target-target components. Section III describes the diagnostics that will be required for D-T Q=1 breakeven, with emphasis on the neutron and alpha physics and the role of TFTR diagnostics in relation to future ignition experiments.
