Abstract

We propose an alternative route to the conventional production of Gas Electron Multiplier (GEM) type detectors used in nuclear and particle physics for radiation detection. Currently such detectors, as used at CERN for example, are produced by lithography and chemical etching. Such a method limits geometric variations of the devices and is relatively slow in the production of modified designs. We propose that multi-material 3D printing via material jetting offers a new, rapid and adaptable manufacture method of the required hybrid organic-inorganic layer structure. The proposal is based on advanced methods for 3D printing, in which the University of Nottingham has a record of developing printers and formulations suitable for this purpose alongside an advanced suite of material analysis instrumentation to characterise the interfaces of the materials. This research project has the potential to generate disruptive impact on High Energy Physics experiments and facilities that will benefit from novel/improved designs of GEMS. (AU)
