Lighting at the Panama–Pacific International Exposition, 1915, designed by Ryan, including the Scintillator searchlight display. Walter D'Arcy Ryan (Kentville, Nova Scotia, Canada, April 17, 1870 – Schenectady, New York, US, March 14, 1934) was an influential early lighting engineer who worked for General Electric as director of its Illuminating Engineering Laboratory.
The following is a list of commonly used inorganic crystals: BaF 2 or barium fluoride: BaF 2 contains a very fast and a slow component. The fast scintillation light is emitted in the UV band (220 nm) and has a 0.7 ns decay time (smallest decay time for any scintillator), while the slow scintillation light is emitted at longer wavelengths (310 ...

Joseph Crookes had had five children with his first wife; two sons from that marriage, Joseph and Alfred, took over the tailoring business, leaving William free to choose his own path. [7] In 1848, at age 16, Crookes entered the Royal College of Chemistry (now the Imperial College chemistry department) to study organic chemistry.
ZEPLIN-II was the first two-phase system deployed to search for dark matter in the world; [2] it consisted of a 30 kg liquid xenon target topped by a 3 mm layer of gas in a so-called three-electrode configuration: separate electric fields were applied to the bulk of the liquid (WIMP target) and to the gas region above it by using an extra ...

This novel development, termed the continuous phoswich scintillator and detector, provides a number of bits of depth-of-interaction (DOI) information, a significant improvement over the 1 to 2 bits available previously with discrete phoswich scintillators.
