  1. Pierre Auger Observatory Fluorescence detector camera: 440 PMT • Photonis XP3062 • Hexagonal • bi-alkali • 8 stage

  2. Anodic sensitivity

  3. Experimental set up

  4. XP3062, SN: 041208, 370 nm

  5. Photonis XP5602 • Round • Ø effective = 56 mm • bi-alkali • 8 stage

  6. Hamamatsu R1387 • Round • Ø effective = 34 mm • Multialkali • 10 stage Susete Fetal

  7. Scanning system using a variable number of photons Susete Fetal

  8. PMT: Hamamatsu R1387 SN: ND8920 HV = -750 V LED: NICHIA NSHU590, λ = 370 nm

  9. PMT: Hamamatsu R1387 SN: ND8932 HV = -750 V LED: NICHIA NSHU590, λ = 370 nm
