title = "Measurement of pressure dependent fluorescence yield of air: Calibration factor for UHECR detectors",
abstract = "In a test experiment at the Final Focus Test Beam of the Stanford Linear Accelerator Center, the fluorescence yield of 28.5 GeV electrons in air and nitrogen was measured. The measured photon yields between 300 and 400 nm at 1 atm and 29 °C areY(760Torr)air=4.42±0.73andY(760Torr)N2=29. 2±4.8photons per electron per meter. Assuming that the fluorescence yield is proportional to the energy deposition of a charged particle traveling through air, good agreement with measurements at lower particle energies is observed.",
