Description
Ionization profile monitors in accelerator beamlines rely on delicate wire grids with high optical transparency, but conventional wire fabrics are prone to shortcuts or sparkovers to nearby high-voltage components due to loose wires and can therefore cause malfunction. In the presented concept, additive manufacturing is explored as a route to produce more robust grid structures for IPMs, with current work focusing on alternative geometries such as honeycomb- or triangle-like patterns, which improves mechanical stability and reduced sagging. Thermal deformation during heating up to 300°C needs to be considered. The study also addresses lifetime extension toward maintenance-free operation and examines whether tailored surface properties of additively manufactured parts, including secondary electron yield, can improve performance. Beyond ionization profile monitors, the approach may open new options for other beam diagnostics such as profile grids and wire scanners.
