I use filament cathodes to produce a plasma. The plasma is then extracted using my grid system. Thanks for asking...

Ion Times We Have The Power! Just when you thought it was safe to go back in the lab, lurking below the surface of your coating system is an ancient power supply that could die at any moment! You thought you could repair him, but suddenly, no one makes that part anymore! What will you […]
Ion Times Replacing your RFN Collector Collector replacement should happen each and every time your RFN is cleaned. The collector in your RFN is fabricated of Nickel that can react with Oxygen when it gets hot. Unfortunately, these reactions occur both on the surface and deep inside, meaning that a collector cannot be “cleaned” like […]
Ion Times Ion-Assisted Deposition Turning down a sale is always painful – money that could have been made, if only you had the capacity or capability to meet the requirement. As coating specifications and tolerances become more challenging, you may find yourself unable to meet customers’ needs with a standard evaporative coater. With this in […]
Ion Times QCM Sensitivity with IBAD Have you ever observed the QCM deposition rate dipping below zero at the beginning of a coating (see the figure below)? Is the QCM losing mass or is the measurement sensitivity just too low? The answer is neither. The QCM measures mass by differences in its resonant frequency. However, […]
