Issues And Options For Mirrors Of CXRS And H-alpha ITER Diagnostics

摘要

The present status of investigations on the first mirror (FM) problem is discussed on the basis of the last experimental results obtained in modern tokamaks and laboratory devices. Engineering solutions that are necessary for protection of Fms for CXRS and H-alpha diagnostics are considered. Future plans for R&D that has yet to be done are presented. Results of neutron irradiation and heating tests of multilayered dielectric mirrors are given briefly.
