Attention and scintillation

Vision Research, 2003
The scintillating grid is a recently discovered visual illusion, created by superimposing white discs on the intersections of orthogonal gray bars on a black background. Even though the entire display is stationary, observers perceive dark spots appearing and disappearing rapidly within some of the white discs.

X-ray Photon Counting and Two-Color X-ray Imaging Using Indirect Detection

Sensors, 2016
In this paper, we report on the design and performance of a 1 cm2, 90 × 92-pixel image sensor. It is made X-ray sensitive by the use of a scintillator.

Development and properties of cadmium and lead tungstate low-background scintillators for double beta decay experiments [PDF]

Ядерна фізика та енергетика, 2014
Methods of deep purification of natural and isotopically enriched cadmium (Cd, 106Cd, 116Cd), as well as of archaeological lead (archPb), to produce cadmium and lead tungstate crystal scintillators have been developed. The basic stages of development and
