Frequently Asked Questions
Why use glazed alumina tubes for ion repellers? How do they prevent high-voltage arcing in UHV?
In high-vacuum analytical instruments and ion sources, unglazed or micro-porous ceramics can trap moisture and organic contaminants, leading to surface tracking and catastrophic high-voltage breakdown. Glazed alumina ceramic tubes provide an ultra-smooth, non-porous dielectric surface that significantly reduces outgassing in ultra-high vacuum (UHV). This prevents electrical flashover between the repeller electrode and surrounding chambers, ensuring stable ion beam focusing and acceleration.
Looking for a custom ceramic insulator manufacturer? Can internal threads and alumina purity grades be tailored?
Yes. As an advanced technical ceramic manufacturer, INNOVACERA designs and fabricates custom ion repeller insulator tubes. We offer precision internal machining (such as M3, M4, or imperial threads), customized wall thicknesses, selective surface glazing, and high-purity material upgrades (99% to 99.8% Alumina) to fit proprietary ion source assemblies and OEM mass spectrometer platforms.
