Abstract
We present experimental studies on how Raman based temperature sensors undergone two different treatments: gamma-radiation and H-loading. Unfortunately, gamma radiation and hydrogen release in harsh nuclear environment can affect the temperature measurements based on this technology of sensor, limiting the sensor performances. Moreover, the Raman device response in both cases changes with the different classes of multimode fibers that are used by the engineers.
