Effects of helium implantation with heavy ion irradiation on deuterium permeation in yttrium oxide coating

In a fusion reactor, strict control of tritium is required from the viewpoints of sufficient fuel balance and radiological hazard. Fabrication of tritium-impermeable ceramic coatings is a promising solution, and ceramic coatings have been investigated for several decades. In recent years, several ir...
