We investigate the response of Ge-doped, P-doped,pure-silica, or Fluorine-doped fibers to extreme environmentscombining doses up to MGy(SiO ) level of 10 keV X-rays andtemperatures between 25 C and 300 C. First, we evaluate theirpotential to serve either as parts of radiation tolerant optical oroptoelectronic systems or at the opposite, for the most sensitiveones, as punctual or distributed dosimeters. Second, we improveour knowledge on combined ionizing radiations and temperature(R&T) effects on radiation-induced attenuation (RIA) bymeasuring the RIA spectra in the ultraviolet and visible domainsvarying the R&T conditions. Our results reveal the complex responseof the tested fibers in such mixed environments. Increasingthe temperature of irradiation increases or decreases the RIAvalues measured at 25 C or sometimes has no impact at all.Furthermore, R&T effects are time dependent giving an impact ofthe temperature on RIA that evolves with the time of irradiation.The two observed transient and stationary regimes of temperatureinfluence will make it very difficult to evaluate sensor vulnerabilityor the efficiency of hardening approaches without extensive testcampaigns.
