Improved photoionization mass spectrometer [PDF]

, 1970
Improved spectrometer for gas analysis lessens the intensity problem that occurs in obtaining dispersed ultraviolet radiation. A filter, consisting of a selectively transmitting gas cell, a thin film or mirror, or a predispersing grating, alleviates ...

Triple resonant four-wavemixing boosts the yield of continuous coherent VUV generation

, 2012
Continuous-wave coherent radiation in the vacuum ultraviolet (VUV)wavelength region at 121 nm will be essential for future laser-cooling of trapped antihydrogen [1].

Extreme surface solar ultraviolet radiation events reduce maize yields in China

Communications Earth & Environment
Over recent decades, changes in atmospheric ozone and climate have substantially altered surface solar ultraviolet radiation, but the impacts of these changes on crop yields remain unclear.

Hawking Radiation and Ultraviolet Regulators [PDF]

, 1995
Polchinski has argued that the prediction of Hawking radiation must be independent of the details of unknown high-energy physics because the calculation may be performed using `nice slices', for which the adiabatic theorem may be used.
