Measurement of the near-infrared fluorescence of the air for the detection of ultra-high-energy cosmic rays
Astroparticle Physics(2011)
摘要
We have investigated the fluorescence emission in the near infrared from the air and its main components, nitrogen and oxygen. The gas was excited by a 95 kV electron beam and the fluorescence light detected by an InGaAs photodiode, sensitive down to about 1700 nm. We have recorded the emission spectra by means of a Fourier Transform Infrared spectrometer. The light yield was also measured by comparing the near infrared signal with the known ultraviolet fluorescence, detected by a Si photodiode. The possibility of using the near infrared fluorescence of the atmosphere to detect ultra-high-energy cosmic rays is discussed, showing the pros and the cons of this novel method.
