EJ-309 Quenching Data

EJ-309 relative light yield in MeVee as a function of proton energy from 0.2 to 6 MeV. The discrepancy between the different reported proton light yield measurements can be explained in part by differences in the integration lengths used to measure the light output [Brown2018JourApplPhys124, Laplace2020NIMA959], bias associated with characterization of the Compton edge used for light output calibration [Dietze1982NIMA193], and bias associated with the edge characterization method used by some authors [Weldon2020NIMA953]. Most often ignored, non-proportionality of the electron light yield [Payne2011IEEE58, Swiderski2012JINST7] may also introduce further biases in calibration/conversion to the MeVee light unit. In some cases, fit functions provided by the authors are shown in lieu of the original measurements due to challenges in extracting data points from the published graphs.
