摘要:

测量报告的产量和光谱的荧光,激发的28.5 GeV的电子束,在空气中的超高能宇宙射线探测器感兴趣的压力范围。波长范围为300 - 420 nm。利用氮激光束的瑞利散射进行了系统校准。在304 K的大气压干燥空气中,产额为20.8 +/- 1.6光子/MeV。

英文摘要:

Measurements are reported of the yield and spectrum of fluorescence, excited by a 28.5 GeV electron beam, in air at a range of pressures of interest to ultra-high energy cosmic ray detectors. The wavelength range was 300 - 420 nm. System calibration has been performed using Rayleigh scattering of a nitrogen laser beam. In atmospheric pressure dry air at 304 K the yield is 20.8 +/- 1.6 photons per MeV.
