Nishihara, Time-resolved two-dimensional profiles of electron density and temperature of laser-produced tin plasmas for extreme-ultraviolet lithography light sources, Scientific Reports 7 12328(7pages) (2017), 2017.10, Time-resolved two-dimensional (2D) profiles of electron density (ne) and electron temperature (Te) of
extreme ultraviolet (EUV) lithography light source plasmas were obtained from the ion components
of collective Thomson scattering (CTS) spectra. The highest EUV conversion efficiency (CE) of 4% from
double pulse lasers irradiating a Sn droplet was obtained by changing their delay time. The 2D-CTS
results clarified that for the highest CE condition, a hollow-like density profile was formed, i.e., the high
density region existed not on the central axis but in a part with a certain radius. The 2D profile of the inband
EUV emissivity (ηEUV) was theoretically calculated using the CTS results and atomic model (Hullac
code), which reproduced a directly measured EUV image reasonably well. The CTS results strongly
indicated the necessity of optimizing 2D plasma profiles to improve the CE in the future..

(Fast Track Communications), Vol. 46, 382001 (5 pages) (2013), 2013.09, Spatiotemporal evolutions of electron density (ne) were successfully measured in decaying SF6 gas-blast arc discharges formed with a long gap (50 mm) in a confined nozzle using laser Thomson scattering. Precise electron density measurement was so far difficult for a long-gap decaying arc discharge in a circuit breaker because of its instability, although it is well known as essential parameter for determination of success or failure of the current interruption in a circuit breaker. Pure Ar gas and 80%Ar/20%SF6 mixture gas were used as arc quenching media at atmospheric pressure. After current zero, measured ne and the arc radius in the Ar/SF6 gas arc clearly decayed more rapidly than in the pure Ar gas arc..
