  2. Precious Plastic - Wikipedia

    en.wikipedia.org/wiki/Precious_Plastic

    Precious Plastic is an open hardware plastic recycling project and is a type of open source digital commons project. The project was started in 2013 by Dave Hakkens and is now in its fourth iteration. It relies on a series of machines and tools which grind, melt, and inject recycled plastic, allowing for the creation of new products out of ...

  3. Cherenkov detector - Wikipedia

    en.wikipedia.org/wiki/Cherenkov_detector

    Cherenkov threshold detectors have been used for fast timing and time of flight measurements in particle detectors. More elaborate designs use the amount of light produced. Recording light from both primary and secondary particles, for a Cherenkov calorimeter the total light yield is proportional to the incident particle energy.

  5. Infrared open-path detector - Wikipedia

    en.wikipedia.org/wiki/Infrared_open-path_detector

    An open path detector usually costs more than a single point detector, so there is little incentive for applications that play to a point detector's strengths: where the point detector can be placed at the known location of the highest gas concentration, and a relatively slow response is acceptable. The open path detector excels in outdoor ...

    Microscopic photograph of deuteron tracks in CR-39. A solid-state nuclear track detector or SSNTD (also known as an etched track detector or a dielectric track detector, DTD) is a sample of a solid material (photographic emulsion, crystal, glass or plastic) exposed to nuclear radiation (neutrons or charged particles, occasionally also gamma rays), etched in a corrosive chemical, and examined ...

  7. Microchannel plate detector - Wikipedia

    en.wikipedia.org/wiki/Microchannel_plate_detector

    In a delay line detector the electrons are accelerated to 500 eV between the back of the last MCP and a grid. They then fly for 5 mm and are dispersed over an area of 2 mm. A grid follows. Each element has a diameter of 1 mm and consists of an electrostatic lens focusing arriving electrons through a 30 μm hole of a grounded sheet of aluminium.

  8. Detectors for transmission electron microscopy - Wikipedia

    en.wikipedia.org/wiki/Detectors_for_transmission...

    For electron microscopes, film typically consisted of a gelatin and silver halide emulsion layer on a plastic support base. [2] The silver halide would be converted to silver upon exposure to the electron beam, and the film could then be chemically developed to form an image, which could be digitized for analysis using a film scanner. [2]

  9. Infrared detector - Wikipedia

    en.wikipedia.org/wiki/Infrared_detector

    An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic ( photodetectors ). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. [ 2 ]
