Abstract

An engineering feasibility study on the mirror-based fusion plasma neutron source as a fusion engineering test facility (FEF) has been carried out. The engineering issues and conditions to meet the requirement are presented. The radius and length of the plasma are about 10 cm and about 4 m, respectively. The wall loading of 14 MeV neutrons is about 1-2 MW/m2, and the required electric power is about 100-150 MW. The critical issues are as follows: (i) the heat lead to the first wall of the central cell and plug cell, which depends strongly on charge exchange neutrals. Methods to reduce the charge exchange in the plug cell are discussed. (ii) The blistering on the Faraday shield and the guard limiter of the ICRF antenna due to the bombardment of the alpha particles is the second critical issue. Some optimization has been considered.
