Özet
The MALTA family of depleted monolithic pixel sensors produced in TowerJazz 180 nm CMOS technology target radiation hard applications for the HL-LHC and beyond. Several process modifications and front-end improvements have resulted in radiation hardness >10(15) 1 MeV n(eq)/cm(2) and time resolution below 2 ns, with uniform charge collection and efficiency across the pixel of size 36.4 x 36.4 mu m(2) with small collection electrode. This contribution will present the comparison of samples produced on high-resistivity epitaxial silicon with Czochralski substrates, before and after neutron irradiation, and results from MALTA2 with a new cascoded front-end flavour that further reduces the RTS noise.
Açıklama
This project has received funding from the European Union?s Horizon 2020 Research and Innova-tion Programme under Grant Agreement Number 101004761 (AIDAinnova) , and Number 654168 (IJS, Ljubljana, Slovenia) . Furthermore it has been supported by the Marie Sklodowska-CurieInnovative Training Network of the European Commission Horizon 2020 Programme under Con-tract Number 675587 (STREAM) . The measurements leading to these results have been performed at the TestBeam Facility at DESY Hamburg (Germany) , a member of the Helmholtz Association (HGF) , and at the E3 beam-line at the electron accelerator ELSA operated by the university of Bonn in Nordrhein-Westfalen, Germany.
