- 摘要：
- We investigated the faint fluorescence spectrum of carbon dioxide in the near-ultraviolet and visible
regions using an intense relativistic electron beam accelerator with an energy of 0.2–0.3 MeV. Monte
Carlo simulations were carried out in advance to maximize the signal-to-noise ratio and a selfnormalization
pulse experimental layout was designed to overcome the shot-to-shot fluctuations in
different pulses of the accelerator. Ultimately, the relative proportion sequences in the near-ultraviolet
and visible regions of a carbon dioxide fluorescence spectrum were successfully obtained for the
first time. The result shows that there exists distinct difference between fluorescence spectrum and
Cerenkov spectrum, which can therefore provide basic support for selectively reducing the unwanted
below-threshold fluorescence response of a carbon dioxide gas Cerenkov medium. Published by AIP
