3d-Printing of Structured Plastic Scintillators — •Philipp Karl Kollar, Fabian Piermaier, Sebastian Ritter, Steffen Schönfelder, and Quirin Weitzel — JGU Mainz

Future experiments at high energy colliders call for calorimeters with high granularity. For scintillator-based sampling calorimeters, scintillator tiles, combined with a SiPM-based readout system, have established as a scalable solution to achieve such high granularity. To simplify production and assembly, structured scintillators-large scintillator plates, divided into optically isolated sections-offer a promising approach. Such structured scintillators can be produced in one single step by 3d-printing, while keeping the design customizable. In this presentation, the quality of 3d-printed scintillators will be discussed based on measurements utilizing cosmic muons. Additionally a comparison to injection-molded scintillators will be presented together with approaches for optimizing printing and polishing methods.
