In this video, I walk through the process of building a dummy load for ion getter pumps—a practical tool for troubleshooting high-vacuum systems like electron and ion columns. Before we dive into the build, I explain how ion pumps work, why they’re essential for ultra-high vacuum (UHV) environments, and how they help monitor pressure by … Continue reading How to Build a Dummy Load for Ion Getter Pumps (and Why You Need One)
