Compared with current silicon strip and hybrid pixels, a significant reduction in the overall detector material thickness is needed to achieve the desired vertex resolution.
We present results of a detailed simulation study of neutron background reduction in dark matter detectors based on observation of nuclear recoils below 100 keV.
A red filter (LEE 182), which transmits visible light of wavelengths greater than 600 nm, was effectively transparent with respect to the light emitted from wound sites, whereas blue and green filters (LEE 183 and LEE 735), which absorb light in the region of 550 – 750 nm, caused a significant reduction in signal reaching the detector when placed between the wounded leaf and the sample stage.
The reduction in thermal noise of the detector was important and was achieved by water-cooling of the detector by 4°C.
This is interesting because it suggests a the possibly dramatic reduction in the need for metal detectors has recently taken place.
In this article studies on dose reduction, different detector technologies, optimization of image acquisition and new technical developments in image acquisition and post processing will be reviewed.
This paper evaluates the performance of a new type of PET detectors called sensitivity encoded silicon photomultiplier (SeSP), which allows a direct coupling of small pitch crystal arrays to the detector with a reduction in number of readout channels.
In addition the decoupled SIC detector has a drastic reduction in the computational cost when compared with its coupled version.
The Empire State Building focused on energy efficiency retrofits including window refurbishment, insulation replacement, thermostat additions, motion detector and infra-red lights, a reduction in plug-load by 40%, and life cycle cost analysis.
As a result, CT scanners equipped with new detectors are expected to have a reduction in patient dose.
