The ELMA research project, jointly presented by UniTS and GSI Laboratories in Darmstadt, Germany, has been awarded a €150,000 grant to conduct a study on the energy response of monolithic active pixel sensors (MAPS).

ELMA is financed by funds from the Ministry of Foreign Affairs and International Cooperation (MAECI) within the framework of the Italy-Germany Cultural Cooperation, which aims to facilitate the access of Italian research personnel to large German research centres.

The research groups of the ELMA project, led by Giacomo Contin from the Physics Department of the University of Trieste and Silvia Masciocchi from the University of Heidelberg and the GSI laboratory, will systematically study the response of MAPS to particles accelerated to certain energies. The researchers will prepare and characterise functional MAPS samples, in planar and curved geometries, and irradiate them at the ion beams of the GSI-FAIR accelerator. The shape and size of the groups of pixels activated by the incident particles with different charge number and energy, and the analogue signal information stored by the detector logic, will be used to study the response and accurately calibrate the sensors for further use in various experimental applications.

The GSI laboratories will make local beam facilities available to the project and provide scientific and technical support.

The project will also provide the opportunity to establish a lasting collaboration between the Italian and German groups, enabling the exchange of students and scientific staff, routine access to each other's facilities, further joint research initiatives and scientific publications.

The funding also made it possible to announce research grants for undergraduate and graduate students and two post-doctoral positions as research assistant who will work on the proposed research and on the fabrication of the necessary setups for data collection.
