In this work, a sensitive and robust vacuum ultra-violet (VUV) single-photon ionization (SPI) ion trap time-of-flight mass spectrometer (VUV-SPI-IT-TOFMS) for on-line, realtime monitoring of chlorinated organic compounds in waste incineration flue ga

A non-uniform voltage distribution across a driven electrode results in inhomogeneous film deposition in large-area, very high-frequency (VHF) plasma reactors. Here we perform experimental and numerical studies on the voltage distribution across the

A two-dimensional simulation code of a discharge-pumped excimer laser was developed to study the effect of spatial discharge non-uniformity on laser output performance. The code consists of a circuit equation, a continuity equation to calculate two-d

Thomson scattering from plasmas in high-pressure discharges for rare-gas-halide excimer-laser pumping was observed using a frequency-doubled 300 ps Nd: YAG laser. A temporal resolution of 1 ns was realized for the Thomson-scattering measurement, and

We have developed a self‐healing mercury‐wetted target as a practical source of soft x‐ray radiation for photoexciting extreme ultraviolet lasers. A threaded rod, rotating in a pool of mercury, demonstrates a soft x‐ray conversion efficiency

A very high frequency (VHF) excited H2 plasma is produced with a ladder-shaped electrode consisted of 17 rods and the plasma parameters are measured with a movable Langmuir probe. When the discharge frequency (∼120 MHz) of the RF power source is in
