论文摘要
在塔楼180 nm CMOS技术中生产的耗尽的单片活性像素传感器（DMAP）的马耳他家族针对HL-LHC及其他地区的辐射应用。几种过程修改和前端的改进导致辐射硬度高达$ 2 \ times 10^{15} 〜1〜 \ text {mev}〜\ text {n} _ {eq}/\ text {eq}/\ text {cm}^2 $ and Time Listolution^2 $ and Time Listoloution^2 ns，在2 ns下，均匀收集效率，均匀的收集效率，均匀尺寸$ 36.4.4.4 36.4.4.4.4.4.4.4.4 36.4.44。 36.4〜μ \ text {m}^2 $，带有$ 3〜μ \ text {m}^2 $电极大小。 Malta2示威者于2021年在高抗性外延硅和Czochralski底物上生产，实现了新的cascoded前端，可降低RTS噪声并具有更高的增益。这项贡献表明了Malta2对2021年CERN SPS测试梁运动的纳秒级时计时解决的结果。
The MALTA family of Depleted Monolithic Active Pixel Sensor (DMAPS) produced in Tower 180 nm CMOS technology targets radiation hard applications for the HL-LHC and beyond. Several process modifications and front-end improvements have resulted in radiation hardness up to $2 \times 10^{15}~1~\text{MeV}~\text{n}_{eq}/\text{cm}^2$ and time resolution below 2 ns, with uniform charge collection efficiency across the Pixel of size $36.4 \times 36.4~μ\text{m}^2$ with a $3~μ\text{m}^2$ electrode size. The MALTA2 demonstrator produced in 2021 on high-resistivity epitaxial silicon and on Czochralski substrates implements a new cascoded front-end that reduces the RTS noise and has a higher gain. This contribution shows results from MALTA2 on timing resolution at the nanosecond level from the CERN SPS test-beam campaign of 2021.
