The Saturation of the Response to an Electron Beam of Ce- and Tb-Doped GYAGG Phosphors for Indirect β-Voltaics

Applied Sciences, 2023
GYAGG:Tb (Ce) scintillators have been confirmed to be promising sources of light emission when excited by an intense 150 keV electron beam. The saturation of the scintillation yield under such excitation conditions has been studied.

Low energy light yield of fast plastic scintillators [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2020
Compact neutron imagers using double-scatter kinematic reconstruction are being designed for localization and characterization of special nuclear material. These neutron imaging systems rely on scintillators with a rapid prompt temporal response as the detection medium.

LETTER TO EDITORLight regulation of photosynthetic light harvesting doubles the biomass yield in the green alga Chlamydomonas

Photosynthetica, 2020
Due to the overall low thermodynamic efficiency (1-4%) of photosynthesis (Ort et al. 2011, Subramanian et al. 2013) and its impact on crop productivity, substantial efforts are being made to engineer photosynthesis to improve its light use and carbon ...

Picosecond events in the photochemical cycle of the light-driven chloride-pump halorhodopsin [PDF]

, 1985
The early events in halorhodopsin after light excitation are studied with picosecond time resolution. Absorption and fluorescence measurements show that the electronically excited state of the incorporated retinal has a lifetime of 5 ps. Within that time

Improved yield of photomultipliers for Cherenkov light [PDF]

Nuclear Instruments and Methods, 1979
The combined effects of using a wavelength shifter and higher voltage for better photoelectron collection is shown to give a gain of 70% in the photo-electron yield for the 11 cm diameter phototube RCA 8854 in a typical Cherenkov counter.
