Papers The Development of Novel Resistive Glass Technology to Simplify and Improve Designs in Analytical Instruments 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.

Papers The Development of a Novel Cold Electron Source 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.
