WASHINGTON — NASA is investigating a detector problem common to three primary instruments on the James Webb Space Telescope (JWST) that could get worse with time as a planned 2014 launch date for the ...
The world of laser scanning microscopy is quickly evolving, thanks to the advent of fast and compact detector arrays. These arrays replace the typical single-element detector of traditional confocal ...
Mid-infrared (IR) array detectors have been used for astronomical observations in space. However, the uniformities of their spectral response curves have not been investigated in detail, the ...
THE DESIRE TO DETECT ever fewer photons and ions, including some at great distances from Earth, pushes the frontiers of analytical capability. A symposium at Pittcon in Chicago earlier this month ...

A Japanese team built a sensor so precise, it might have found a way to track dark matter
Dark matter is believed to make up most of the matter in the universe, yet it has never been directly detected. One theory ...
The detector array consists of plastic scintillator detectors, quadrant silicon detectors (QSD), double-sided silicon detectors (DSSD) and high-purity germanium (HPGe) detectors. Exotic nuclei near ...
An immense advantage of EM 2 detectors is that—when calibrated properly—they are noiseless and single ion counting is possible. The essence of an EM is a serial connection of discrete metal plates ...
