Modification of optical properties of tungsten exposed to low-energy, high flux deuterium plasma ions
Anomalous change of optical properties of recrystallized W caused by exposure to D plasma ions at sample temperature of ~535 K was studied by ellipsometry and reflectometry. There is a qualitative difference between the samples reflectivity values measured directly and calculated using ellipsometr...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Anomalous change of optical properties of recrystallized W caused by exposure to D plasma ions at sample
temperature of ~535 K was studied by ellipsometry and reflectometry. There is a qualitative difference between the
samples reflectivity values measured directly and calculated using ellipsometric data. A physical model of the
phenomenon is suggested. It is shown that on the W surface exposed at ~535 К two processes take place 1) blistering
and 2) modification of electron structure in the upper-most layer. |
