Description
The MALTA monolithic active pixel sensor produced in TowerJazz 180 nm CMOS technology with pixels of size 36.4 x 36.4 um2 and a 3 µm2 electrode. As part of the MALTA family, the MALTA2 demonstrator features an asynchronous readout with cascoded front-end and demonstrates time resolution below 2 ns with radiation hardness up to 3e15 n/cm2. As such, the MALTA family is a compelling candidate for tracking detectors for the HL-LHC and beyond. This contribution will show results from irradiated MALTA2 produced on both high-resistivity epitaxial silicon and on Czochralski substrates, obtained during the 2022 testbeam campaign at CERN SPS North Area. The timing performance of MALTA2 sensor irradiated to 3e15 n/cm2 will be presented along with the detector efficiency. Future chip designs will also be discussed.
