Luminosity Spectrometer Calibrations

Photomultipliers:
- R5600: This is cylindrical PMT of 16mm diameter and 12mm height. Its price is about DM800.
- R7400: This is the same as R5600, but with 30% increased photo-electron yield with respect to R5600.
- R5900 (very expensive DM1600)

Early (BPC) documentation on PMTs:
PMT tests in 1996 (incomplete report).

Calibration Tools:
- LED
- Charge Injection
- Radioactive Sources
