We present the Positron Research Infrastructure (pELBE) at the ELBE linear accelerator at the HZDR as one facility of the ReMade@ARI (REcyclable MAterials  DEvelopment at Analytical Research Infrastructures) project of the Horizon Europe program.

pELBE is a collection of methods and instruments that can characterize defects, determine open volumes and investigate open or closed microporous systems using positron annihilation spectroscopy. It is used for studying a variety of phenomena and material properties on an atomic scale. For example performance parameters in solar cells by characterization of the defect concentration, optimization of process parameters for thin polymer membranes regarding free volume effects or determination of pore size distribution in nano filters for high-performance applications. Being the anti-particle of electrons, positrons are used to probe material defects at low concentrations and with high sensitivity. With the advantage of being a non-destructive materials research method, positron annihilation has been developed as a well established tool for investigations of metals, semiconductors, polymers and porous materials.

The ReMade@ARI project is committed to foster the development of innovative, sustainable materials for key components in a wide range of sectors, including electronics, batteries, vehicles, construction, packaging, plastics, textiles, and food. It provides access to around 50 research infrastructures and encourages the use of complementary techniques. Including full service for training and assistance for experiments or materials characterizations. The project aims to simplify the use of large-scale research facilities within Europe for both academic and industrial partners in the circular economy. The poster will provide a closer look at the outline of the project as well as the positron research infrastructure (pELBE) at HZDR.
