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 ...
In high energy physics detectors, shashlik is a layout for a sampling calorimeter.It refers to a stack of alternating slices of absorber (e.g. lead, brass) and scintillator materials (crystal or plastic), which is penetrated by a wavelength shifting fiber running perpendicular to the absorber and scintillator tiles.
These simple but special detectors became possible in the conditions of ESEM, since bare plastic does not charge by the BSE. However, a very fine wire mesh with appropriate spacing has been proposed [40] as a GDD when gas is present and to conduct negative charge away from the plastic detectors when the gas is pumped out, towards a universal ...
Detectors are designed to have one or two scintillation materials, depending on the application. "Single phosphor" detectors are used for either alpha or beta, and "Dual phosphor" detectors are used to detect both. [8] A scintillator such as zinc sulphide is used for alpha particle detection, whilst plastic scintillators are used for beta ...
In order to counteract this, the expensive and small high resolution detector is surrounded by larger and cheaper low resolution detectors, usually a scintillator (NaI and BGO are the most common) [4] The suppression detector is shielded from the source by a thick collimator, and it is operated in anti-coincidence with the main detector: if ...
An electron backscatter diffraction pattern of monocrystalline silicon, taken at 20 kV with a field-emission electron source. Electron backscatter diffraction (EBSD) is a scanning electron microscopy (SEM) technique used to study the crystallographic structure of materials.

UA3 detector in vacuum chamber. The experiment shares the same intersection region used as the UA1 colliding experiment, and looked for expected high ionisation of magnetic monopole in plastic detectors. [3] The beam pipe was a stainless steel corrugated cylinder, with 0.2 mm thickness. [4]
