A Prototype GEM Detector with 3D-Printing Technology — Till Mayer, •Alexander Austregesilo, Florian Kaspar, and Stephan Paul — Technische Universität München

GEM (Gas Electron Multiplier) detectors are widely used in modern high-energy physics experiments. They provide precise tracking information, have a high-rate capability and a low material budget. However, their production is delicate and time-consuming. Especially the support structures made of fiber-glass frames are expensive and difficult to machine.

The high-end engineering plastic PEEK is extensively used in aerospace, automotive, and chemical process industries. Its low outgassing, electrical insulation and high stiffness make it ideal for the design of GEM detectors. We explored the novel approach to process PEEK with a 3D-printer. A first GEM detector with printed support structures was already built and tested. We will report on the performance of this prototype regarding stability and aging. The next steps towards the realization of a fully 3D-printed GEM detector will also be presented.
