Improving light yield measurements for low-yield scintillators
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2019 Light power spectra are introduced as a new tool for relative light yield (LY) determinations. Light event spectra have commonly been used for this purpose. Theoretical background supporting this change is provided. It is shown that the derivative of a light power spectrum can provide a reliable LY measurement at levels as low as 2% of those for high ...

Binary masks yielding Gaussian light distributions in Maxwellian view [PDF]
Vision Research, 1997 Gaussian light distributions are important stimuli for vision research, but are difficult to produce for Maxwellian viewing conditions. In this study, two binary Maxwellian-view masks which produce smooth light distributions on the retina were considered: one was an out-of-focus circular aperture; the other was an in-focus pattern of opaque squares ...

Influence of a Surface Finishing Method on Light Collection Behaviour of PWO Scintillator Crystals
Photonics, 2018 In the field of scintillators, high scintillation and light production performance require high-quality crystals. Although the composition and structure of crystals are fundamental in this direction, their ultimate optical performance is strongly ...

A very high light-yield imaging chamber [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1991 Abstract By operating the parallel-plate imaging chamber in a nonproportional regime it was possible to increase the light yield from the gas avalanches by a factor in excess of 10 4 over the proportional operation. At this higher gain, the avalanches can easily be seen with the naked eye in a moderately lit room and recorded with CCD cameras ...

A separation of the reactions in photosynthesis by means of intermittent light [PDF]
, 1932 Experiments on photosynthesis in intermittent light have been made on two occasions. Brown and Escombe, in 1905, made use of a rotating sector to study the effect of light intensity on the photosynthesis of leaves.
