Hamamatsu Photonics Europe Circular MCP: Low vacuum operation, compact demountable package F14844

Next-generation ion detector ideal for miniature portable mass spectrometers operating at high pressure (1 Pa). The F14844 is an MCP assembly with a unique triode structure*1 designed to vary the potential gradient and to suppress ion feedback*2 noise. This makes the F14844 a useful tool for portable desktop mass spectrometers in which it is difficult to install a large vacuum pumping system. The F14844 is a breakthrough ion detector that allows downsizing and cost reduction of the equipment. *1: Structure consisting of three electrodes which are the MCP-out, mesh anode, and dynode. *2: Ion feedback is the cause of unstable operation that occurs under low vacuum conditions
