Explore the Palermo g-ray irradiation facility for semiconductor testing and evaluation. Projects include R2RAM, E2COGaN, D2SENSE, and past initiatives like E2SG and RHESSA. Test chips for CMOS technology, rad-tolerant devices, and layout transistors are investigated. MaTeRiALabs offers progressive levels for research in spectroscopy, modeling, and simulation at UniCal Nexus Lab.
