What is the difference between Detector quality, Imaging quality and Premium quality MCPs apart from their price?
A.- Any batch of MCPS produced will have a certain quantity with a very small number of physical defects such as areas of missing channel walls or holes. Out of this batch Detector quality MCPs will be those selected that do have some of these defects that would mean that if the MCP was used in an imaging application at its highest spatial resolution the image could have a few small blemishes in it. However for signal detection applications such as used in time-of-flight mass spectrometry, residual gas analysers, point source detectors and even multi-electrode detectors the Detector Quality will perform to the highest specification and so are the preferred choice. Image quality MCPs are by definition those selected without image impairing defects such that they can be used in conjunction with an appropriate readout to provide an intensified high spatial resolution image. So that Image quality MCPs are found in applications such as second generation image intensifier tubes, ultra-fast c
