M3 Threaded Ceramic Insulators for Ion Repellers & High-Voltage Vacuum Systems
Electron gun and ion source assemblies work in harsh conditions—high voltage, high temperatures, and ultra-high vacuum alike. This is especially true for ion repeller insulators, a key interface component where reliable electrical isolation and airtight vacuum sealing are both must-haves. Our glazed alumina ceramic tubes with precision internal threading—engineered as Ion Repeller Ceramic Tubes—are made specifically for these tough applications. As the core insulating part of repeller insulator assemblies, they pair perfectly with alumina bolts, delivering steady performance while ensuring firm mechanical fastening and reliable electrical isolation. High-Vacuum Design: A Core Engineering Challenge Keeping long-term vacuum integrity in high-voltage setups is a classic engineering hurdle. Insulators have to do three jobs at once: act as mechanical support, block electrical current, and seal the vacuum—all while staying stable when hit with thermal and electrical stres...
