Light Source Measurement: Discharge Plasmas for Light Sources-Xe Excimer Lamp-

Light Sources using Energy Transfer from Excimer to Line Radiation

Efficient energy transfer between neon excimer molecules and hydrogen has been found. A small, high gas density light source has been developed, emitting entirely on the hydrogen 2p-l s transition at I 21 .567nm (Lyman-a). Light output densities of lOW/cm2 are obtained. Electron beam energy conversion efficiencies of lO% have been measured.

Safety standards and measurement techniques for high intensity light sources.

New source technologies and their impact on future light sources

Emerging technologies are critically evaluated for their feasibility in future light sources. We consider both new technologies for electron beam generation and acceleration suitable for X-ray free-electron lasers (FELs), as well as alternative photon generation technologies including the relatively mature inverse Compton scattering and laser high-harmonic generation. Laser-driven plasma wakefi...

Hydrogen Peroxide Photolysis with Different Uv Light Sources including a New Uv-led Light Source

Hydrogen peroxide 0.1% was photolyzed using 17W low pressure mercury arc lamp and 125 W high pressure mercury arc lamp. The decomposition kinetics was followed through the pseudofirst order kinetics and different conditions of temperature and pH were explored. H2O2 0.1% was also photolyzed at 360 nm through a new UV-LED 3W light source using a flow reactor. The kinetics rate constant achieved w...
