Abstract

Statement of Problem & DOE/Public Interest: In advanced fusion machines, high current beams (megamps) of relativistic electrons (10s of MeV) can cause severe damage to plasma-facing surfaces of a tokamak structure (Runaway Electrons, or RE). This catastrophic destruction includes melt damage, coolant leaks, loss of vacuum, and if it occurs once in every 1000 shots could prevent fusion machines from reaching commercial viability.
It is in the public’s interest for DOE to investigate a scientific solution applicable across the fusion industry. All fusion machines can therefore benefit from an effective and timely resolution to a critical problem.
Diversified Technologies, Inc. (DTI) proposes to develop a fast-acting high current switch and vacuum feedthrough controlling a magnetic coil designed to suppress formation of the relativistic beams and thereby protecting the fusion machines.
How the Problem Will Be Addressed: DTI proposes to develop a vacuum feedthrough and fast-acting, high current switch controlling a magnetic coil which eliminates destructive electron beams from fusion machines. The problem will be addressed by theoretical design, numerical analyses, and hardware construction. The full-scale switch and feedthrough will be installed in a working fusion device for full-scale tests. The concept is being worked with MIT and General Atomics (GA) for future installation on the GA fusion device (DIII-D) as a prototype.
Phase I Work: DTI will design the switch and feedthrough and test critical components thereof. Analytical designs, numerical modeling and critical component hardware fabrication will be performed to establish feasibility.
Commercial Applications and Benefits: The fusion industry is growing rapidly focused on high current, high magnetic field machines. These machines are the target market Diversified Technologies, Inc. estimates cumulative sales revenues of ~$6.4M during the first 10 years of commercialization.
