Abstract
A photomultiplier tube (PMT) detector assembly includes a PMT and an analog PMT detector circuit. The PMT includes a photocathode configured to emit an initial set of photoelectrons in response to an absorption of photons. The PMT includes a dynode chain with a plurality of dynodes. The dynode chain is configured to receive the initial set of photoelectrons, generate at least one amplified set of photoelectrons, and direct the at least one amplified set of photoelectrons. The PMT includes an anode configured to receive the at least one amplified set of photoelectrons, with a digitized image being generated based on a measurement of the final amplified set of photoelectrons. The digitized image is corrected by applying an output of the signal measured by the analog PMT detector circuit to the digitized image.
