The Material-Plasma Exposure eXperiment (MPEX), a superconducting magnet, steady-state device, is being constructed at Oak Ridge National Laboratory (ORNL), going forward referred to as “the Company,” to address the harsh conditions inside a fusion reactor. This device, as designed, will have the unique feature of conducting accelerated lifetime tests of plasma-facing components, including those that have experienced neutron damage. MPEX will utilize a new high-intensity plasma source concept based on RF technology. This source concept will allow coverage of all expected plasma conditions in the divertor of a future fusion reactor, including very high densities. It will be able to study erosion and redeposition in correct geometries with relevant electric and magnetic fields in front of the target.
The Helicon system is one of three plasma production and heating systems on MPEX. It consists of RF transmitters, transmission line, and a launcher that injects the radiofrequency waves into the plasma. The Helicon system is the primary system to generate the plasma.
