The Material Plasma Exposure eXperiment (MPEX) has completed its design phase. MPEX will be a unique facility to investigate plasma material interactions (PMIs) under fusion prototypic divertor conditions in steady state. This includes exposure expected reactor divertor. Materials investigated include solids, liquids, and neutron pre-irradiated materials. Electron ion heating allow for large operational domain ranging from erosion-dominated PMI deposition-dominated conditions. An overview of...
The Material Plasma Exposure eXperiment (MPEX) vacuum pumping system is responsible for creating prototypic conditions in the plasma material interaction chamber that mimic those a fusion reactor divertor region.

The Material Plasma Exposure eXperiment (MPEX) device is a linear plasma developed to perform material interaction experiments under the conditions prototypic of fusion reactor divertor. MPEX has multiple systems that must be precisely aligned axis, including an electron cyclotron heating system emits up 400 kW microwave power into vacuum vessel. Five distinct require precise alignment on device, thus requiring four bellows, all which are adjacent at relatively high heat flux approximately...
The Material Plasma Exposure eXperiment (MPEX) project seeks to design a steady-state linear plasma facility at Oak Ridge National Laboratory that will be used study plasma-material interactions (PMIs) fusion prototypic levels, supporting the evaluation and development of materials for next generation devices. This is focused on PMI exposure small-size neutron-irradiated specimens, which are clamped onto an actively cooled component. A thermohydraulic new MPEX target assembly assess...
