The origins<\/h2>\n\n\n\n
\n
\n

The Padova GRIT group ha been established in the ’90s by prof. Dario Bisello of Padova University to support the development of the silicon microstrip sensors constituting the tracker of the CMS experiment at the CERN Large Hadron Collider (LHC). A pioneering effort at the time, the CMS tracker has been the first fully-monolithic tracking system employed in High Energy Physics.<\/p>\n<\/div>\n\n\n\n

\n

The extreme radiation conditions at which the LHC experiments operate mandated for extensive R&D in material properties and electronic design to ensure the detectors survival through the whole experiment lifetime.<\/p>\n<\/div>\n<\/div>\n\n\n\n

The SIRAD radiation hardness facility<\/h2>\n\n\n\n

\n

The necessity for testing devices against the high radiation doses found the the LHC experiments, far higher than those found in the harshest space environment, led the group to create the state-of-the-art SIRAD<\/a> beamline facility at the Legnaro National Laboratory<\/a>. The SIRAD beamline allows testing materials and electronic devices with heavy ions on a wide range of energies. <\/p>\n<\/div>\n\n\n\n

To extend the capability of the SIRAD beamline, the group developed an Ion Emission Electron Microscope (IEEM)<\/p>\n<\/div>\n\n\n\n

to micro-map the effect of single particles hits on an electronic device (SEE mapping).<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

Contribution to major experiments <\/h4>\n\n\n\n
\n
\n

Padova GRIT collaborated with several major experiments and R&D efforts, especially but not limited to the field of High Energy Physics, to assess and qualify the radiation response of various electronic devices and detector meant to operate in hostile radiation environments, from space missions to underground experiments.<\/p>\n\n\n\n
