MALTA3: Concepts for a new radiation tolerant sensor in the TowerJazz 180 nm technology
/ Dobrijević, Dominik (CERN ; U. Zagreb (main)) ; Allport, Phil (Birmingham U.) ; Asensi, Ignacio (CERN) ; Berlea, Dumitru-Vlad (DESY, Zeuthen) ; Bortoletto, Daniela (U. Oxford (main)) ; Buttar, Craig (Glasgow U.) ; Dachs, Florian (CERN) ; Dao, Valerio (CERN) ; Denizli, Haluk (Abant Izzet Baysal U.) ; Flores, Leyre (CERN) et al.
The upgrade of the MALTA DMAPS designed in Tower 180 nm CMOS Imaging process will implement the numerous modifications, as well as front-end changes in order to boost the charge collection efficiency after the targeted fluence of 1x10$^{15}$ 1 MeV$n_{eq}$/cm$^{2}$. The effectiveness of these changes have been demonstrated in recent measurements with a small-scale Mini-MALTA demonstrator chip. [...]

To achieve the physics goals of future colliders, it is necessary to develop novel, radiation-hard silicon sensors for their tracking detectors. We target the replacement of hybrid pixel detectors with Depleted Monolithic Active Pixel Sensors (DMAPS) that are radiation-hard, monolithic CMOS sensors. [...]

The last couple of years have seen the development of Depleted Monolithic Active Pixel Sensors (DMAPS) fabricated in TowerJazz 180nm with a process modification to increase the radiation tolerance. While many of MAPS developments focus on low radiation environment, we have taken the development to high radiation environment like pp-experiments at High Luminosity LHC [...]

In this article, a low-power, radiation-hard front-end circuit for monolithic pixel sensors, designed to meet the requirements of low noise and low pixel-to-pixel variability, the key features to achieve high detection efficiencies, is presented. The sensor features a small collection electrode to achieve a small capacitance (<5 fF) and allows full CMOS in-pixel circuitry. [...]

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 $36.4 \times 36.4~\mu\text{m}^2$ with a $3~\mu\text{m}^2$ electrode size.

Radiation Hardness of MALTA2, a Monolithic Active Pixel Sensor for Tracking Applications
/ Berlea, D V (DESY, Zeuthen ; Humboldt U., Berlin (main)) ; Allport, P (Birmingham U.) ; Tortajada, I Asensi (CERN) ; Bortoletto, D (Oxford U.) ; Buttar, C (Glasgow U.) ; Charbon, E (Ecole Polytechnique, Lausanne) ; Dachs, F (CERN) ; Dao, V (CERN) ; Denizili, H (Abant Izzet Baysal U.) ; Dobrijevic, D (CERN) et al.
MALTA is a depleted monolithic active pixel sensor (DMAPS) developed in the Tower Semiconductor 180-nm CMOS imaging process. Monolithic CMOS sensors offer advantages over current hybrid imaging sensors in terms of both increased tracking performance due to lower material budget and ease of integration and construction costs due to the integration of read-out and active sensor into one ASIC.
