Nanosecond Pulse Radiolysis Techniques for the Study of Liquids Using A 600 kV Febetron,
BRITISH COLUMBIA UNIV VANCOUVER DEPT OF CHEMISTRY
Pagination or Media Count:
Some of the ways in which a 600 kV Febetron electron accelerator has been adapted to nanosecond pulse radiolysis studies of liquids are outlined under four categories 1 emission spectroscopy during the pulse and when the medium shows strong self-absorption of its own fluorescence, 2 instantaneous absorption spectroscopy using an internal Cerenkov light source this has been demonstrated by spectrographic and spectrophotometric methods and the sensitivity is such that strongly absorbing species having lifetimes as short as 3 x 10 to the -11 power s may be detected, 3 very fast kinetic studies using laser photometry for monitoring purposes and using the maximum dose rates, 4 a combined flash photolysis-pulse radiolysis arrangement in which part of the electron beam is used for radiolysis and the rest to stimulate a nanosecond light flash in a silvered hemispherical scintillator surrounding the irradiation cell. Advantages of the very intense and short electron pulse are discussed together with the problems associated with weak penetration of 600 kV electrons. Some experimental details are given including methods of dosimetry. Modified author abstract
