In this paper, the output electric pulse characteristics of gallium arsenide photoconductive semiconductor switch (GaAs PCSS) with bias voltage 20 kV and width about 100 ns are studied. By designing reflection transmission optical paths, absorption rate trigger GaAs PCSS at a wavelength 1064 nm was measured to be 24.8%. When is 16 kV-20 kV, avalanche multiplication rates carriers calculated res...
BACKGROUND Younger and older generations may differ substantially in their lifetime smoking habits, which may result in generation-specific health challenges. We aimed to quantify generation shifts in smoking over a period of 25 years. METHODS We used the Doetinchem Cohort Study (baseline 1987-1991; 7768 individuals; 20-60 years; follow-up 1993-2012) and the Longitudinal Aging Study Amsterdam...
