A REVISED ITER EC SYSTEM BASELINE DESIGN PROPOSAL
The ITER EC system is in the process of being revised as a result of the ITER design review that occurred during 2007. This revision is introducing several modifications to the gyrotron and transmission line layout as well as identify several interface issues between the subsystems comprising the EC system. Each modification aims at improving the EC systems performance while reducing the overall cost and increasing reliability. These proposed revisions have now been assembled together into a coherent system design offering an alternative baseline design of the EC system.
The aim of this paper is to review present status of the EC system design highlighting the improvements over the previous baseline design. The proposed changes cover the new RF building, transmission line layout and launchers. In addition, several outstanding issues are still under investigation, which involve the functional aspects of the EC system in heating.
