This paper explores the boundaries of electron multiplication for amplification at pressures above 1x10-4 Torr. Using gain, voltage and dark current measurements in differing multiplier geometries, the maximum operating pressure as a function of voltage and detector gain is presented.
The effects of combining previous research regarding optimizing Microchannel Plates with regards to both optimal resolution parameters and MCP flatness to increase mass resolution by as much as 15%.
Time of Flight Mass Spectroscopy has become the most widely used technique for identifying very large organic molecules. Recently, companies have started designing table top and portable TOF-MS instruments as the market has shifted. In this presentation, you will learn more about the origins of Time of Flight Mass Spectrometry and how our detectors support these instruments.
This paper discusses the development of an MCP-based detector less than 9mm in diameter with a gain of at least 100X. A new technology using brazed ceramic to metal seals was used. Noise tests were done to determine the effects of use in poor vacuum environments.
Microchannel Plates can be modified to function as spontaneous electron emitters. These electron generators are created by altering the microstructure of the MCP channel, so that spontaneously emitted electrons can be produced, causing cascading secondary electrons. The emission current can be varied over a broad range.
This paper characterizes the performance of using an onboard integral high voltage power supply in comparison to a traditional external rack-mounted power supply.
A new proprietary reduced led silicate glass can be made into geometric glass structures. The glass has resistive properties and can create a very uniform electric field to more effectively guide or attract charged particles. The glass can also have thin film metallization points. These geometric structures can be used for drift tubes, ion guides, collision cells, reflectron lenses and more.
This paper examines how Resistive Glass can be used to manufacture reflectron lenses, ion guides, drift tubes and ion sources with similar performance and significantly simplifying the analtyical instrument's design.
An in-depth review of MCP history leading to the development, fabrication and quantification of a 2 micron pore microchannel plate. This new plate allows for a high speed detector with high spatial resolution.
This paper discusses various variations of endspoiling on microchannel plates (MCPs) to evaluate the effects on performance. Gain and spatial resolution variances were tested in both single MCP and Cheveron configurations.

We describe a fast data-driven optical camera, Tpx3Cam, with nanosecond scale timing resolution and 80 Mpixel/sec throughput. After the addition of intensifier, the camera is single photon sensitive with quantum efficiency determined primarily by the intensifier photocathode. The single photon performance of the camera was characterized with results on the gain, timing resolution and afterpu...
