Calibration of photomultiplier arrays [PDF]

Astroparticle Physics, 2010
A method is described that allows calibration and assessment of the linearity of response of an array of photomultiplier tubes. The method does not require knowledge of the photomultiplier single photoelectron response model and uses science data directly, thus eliminating the need for dedicated data sets.

Study of a Miniaturizable System for Optical Sensing Application to Human Cells

Applied Sciences, 2019
Conventional approaches to human intracellular optical sensing, generally, require dedicated laboratories with bulky detection systems. They are performed by cell labeling procedures based on the use of fluorophores that are, mostly, phototoxic, invasive,

A new optical model for photomultiplier tubes

European Physical Journal C: Particles and Fields, 2022
It is critical to construct an accurate optical model of photomultiplier tubes (PMTs) in many applications to describe the angular and spectral responses of the photon detection efficiency (PDE) of the PMTs in their working media.
