6 News 2020 Vol.1 “Triode MCP Assembly” Overturns the Accepted View of What a Microchannel Plate (MCP) Can Do! R&D Interview A completely new and innovative device for ion detection has been developed for use in mass spectrometers that are commonly used to identify substances. It is an MCP assembly designed with a unique triode structure and it overturns the generally accepted view “an MCP cannot be used at low vacuum levels.” Using a detector that operates at low vacuum levels, it will eliminate the need for preparing large vacuum pumps for mass spectro­ meters allowing downsizing and cost reduction of the equipment. As just one of the promising applications, this new MCP assembly is already getting attention as a portable explosive trace detector for airport security.

Let’s hear what they have to say. Making mass spectrometry a handy and easy-to-use tool by approaching issues from a different angle! Ion detector with high gain and stable operation even in low vacuum environments!
