In a photoionization detector, high-energy photons, typically in the vacuum ultraviolet (VUV) range, break molecules into positively charged ions. [2] As compounds enter the detector they are bombarded by high-energy UV photons and are ionized when they absorb the UV light, resulting in ejection of electrons and the formation of positively charged ions.
Medipix-2, Timepix, and Medipix-3 are all 256×256 pixels, each 0.055 mm (55 μm) square, forming a total area 14.08 mm × 14.08 mm. Larger area detectors can be created by bump-bonding many chips to larger monolithic sensors. Detectors of sizes from 2x2 to 2x4 chips are commonly used.
Price First was a bottom-tier, low-priced generic brand that Walmart introduced in late 2013. It included very basic grocery items, trash bags, and paper goods. It was launched as an experimental brand targeted towards the most budget-conscious shoppers. It was the lowest priced brand at Walmart and availability varied by stores.
Mine detectors: A portable, hand-held or worn device to detect buried IEDs. There are many different models from several different companies currently in use worldwide by U.S. and coalition forces.

It became the first HPC detector to be widely used at synchrotron beamlines around the world. [ 2 ] The second generation PILATUS2 systems represented a major technological improvement, featuring a pixel size of 172×172μm, a counter depth of 20 bits and a radiation-tolerant design, necessary for operation with the intense X-ray beams at ...
A millimeter wave scanner at Cologne Bonn Airport, Germany, Europe. A millimeter wave scanner is a whole-body imaging device used for detecting objects concealed underneath a person’s clothing using a form of electromagnetic radiation.
The two most common types of TLDs are calcium fluoride and lithium fluoride, with one or more impurities to produce trap states for energetic electrons.The former is used to record gamma exposure, the latter for gamma and neutron exposure (indirectly, using the Li-6 (n,alpha) nuclear reaction; for this reason, LiF dosimeters may be enriched in lithium-6 to enhance this effect or enriched in ...
Detectors and jammers are illegal to use or to have in a motor vehicle. [19] HRK 2000 (€270) fine if using a jammer. Only confiscation for a detector. Cuba: Illegal Czech Republic: Detectors legal (for example products of leading Czech company Genevo), jammers illegal. Fine up to CZK 10,000 (€388) Ka Egypt: Detectors and jammers are illegal ...
