High-temperature laser induced spectroscopy in nuclear steam generators |
摘要 |
An apparatus and method for conducting optical spectroscopy in a hostile environment comprises a light source, e.g., a laser or an incandescent light connected to a multiplexer for supplying high intensity light to at least two optical fibers. One of the optical fibers extends to a material in the hostile environment to be analyzed. The second optical fiber is connected between the multiplexer and a standard sample for yielding known spectroscopic results. Either the same or additional optical fibers are used to return light from the material to be analyzed. Each optical fiber has an end portion covered by a sheath to shield the optical fiber from the hostile environment. The sheath has an open end covered by a transparent window which is preferably made of diamond, again, to seal and protect the optical fiber in the sheath.
