WebPhotomultiplier tubes (PMTs) are widely used as detectors for laser-induced incandescence (LII), a diagnostics method for gas-borne particles that requires signal detection over a large dynamic range with nanosecond time resolution around the signal peak. WebOct 29, 2024 · Abstract. This work illustrates predominant measureable nonlinearities in photomultiplier tubes (PMTs) and introduces a controllable one called “Superlinearity,” signifying both a positive nonlinear response and the ability to extend linear operation by counteracting gain saturation mechanisms — charge depletion, space-charge field …

For the 1 and 1.5-inch PMTs, the required dynamic range is 15-60,000 photo-electrons (PEs), while the 8-inch PMT should reach a dynamic range of 1-4000 PEs. WFCTA requires the 1-inch PMT's linearity is 2% @ 30mA. qualities of hemingway
