The lifetime of diagnostic equipment in a fusion reactor is typically very short. The first mirror used to reflect optical signals for diagnostics plays a crucial role in the reactor, and it is highly important to develop a more durable first mirror which can survive in the hostile environment. In this work, by conducting electron beam deposition on molybdenum substrates, metallic oxide mirrors are prepared and studied in the simulated environment. The multi-layered metal oxide mirror exhibits much higher reflectivity than the original molybdenum one and the in situ technique to monitor the performance of the first mirror is developed and described. © 2014 Elsevier B.V.
