Over 5000 photomultiplier tubes (PMTs) are being deployed for electromagnetic particle detectors (EDs) for the Large High Altitude Air Shower Observatory (LHAASO) project. The linearity of the PMT signal is optimized using a high dynamic range base. However, the PMT gain and linearity tend to change...
