/ Weick, Julian (Darmstadt, Tech. U. ; CERN) ; Zoubir, A M (Darmstadt, Tech. U.) ; Riedler, P (CERN) ; Berlea, D V (DESY) ; Tortajada, I Asensi (CERN) ; Dobrijevic, D (Zagreb U.) ; Suligoj, Tomislav (Zagreb U.) ; Fasselt, L (DESY) ; Pernegger, H (CERN) ; Snoeys, W (CERN) et al.
With increasing demand for active sensor surface and compact modularization, monolithic active pixel sensors are gaining track in high-energy physics experiments. The analog circuits in these mixed-signal ASICs are often black boxes where the components’ function and the circuitry’s behavior can only be evaluated through simulation or educated guesses. [...]

Measuring the ATLAS ITk Pixel Detector Material via Multiple Scattering of Positrons at the CERN PS
/ Koch, Simon Florian (Oxford U.) ; Moser, Brian (Oxford U. ; CERN) ; Lindner, Antonín (CERN) ; Dao, Valerio (CERN ; SUNY, Stony Brook) ; Asensi, Ignacio (CERN) ; Bortoletto, Daniela (Oxford U.) ; Brekkum, Marianne (CERN) ; Dachs, Florian (CERN) ; Joos, Hans Ludwig (CERN ; Gottingen U., II. Phys. Inst.) ; van Rijnbach, Milou (CERN ; Oslo U.) et al.
The ITk is a new silicon tracker for the ATLAS experiment designed to increase detector resolution, readout capacity, and radiation hardness, in preparation for the larger number of simultaneous proton-proton interactions at the High Luminosity LHC. This paper presents the first direct measurement of the material budget of an ATLAS ITk pixel module, performed at a testbeam at the CERN Proton Synchrotron via the multiple scattering of low energy positrons within the module volume.

Future developments of radiation tolerant sensors based on the MALTA architecture
/ Dobrijević, D (CERN ; Zagreb U.) ; Allport, P (Birmingham U.) ; Asensi, I (CERN) ; Berlea, D (DESY, Zeuthen) ; Bortoletto, D (Oxford U.) ; Buttar, C (Glasgow U.) ; Dachs, F (CERN) ; Dao, V (CERN) ; Denizli, H (Abant Izzet Baysal U.) ; Sanz de Acedo, L F (CERN) et al.
The planned MALTA3 DMAPS designed in the standard TowerJazz 180 nm imaging process will implement the numerous process modifications, as well as front-end changes in order to boost the charge collection efficiency after the targeted fluence of 1 × 10$^{15}$ 1 MeV n$_{eq}$/cm$^{2}$. The effectiveness of these changes have been demonstrated with recent measurements of the full size MALTA2 chip. [...]

Development of the radiation-hard MALTA CMOS sensor for tracking applications
/ Gustavino, G (CERN) ; Allport, P (Birmingham U.) ; Asensi Tortajada, I (CERN) ; Behera, P (Indian Inst. Tech., Madras) ; Berlea, D V (DESY, Zeuthen) ; Bortoletto, D (Oxford U.) ; Buttar, C (Glasgow U.) ; Dachs, F (CERN) ; Dao, V (CERN) ; Dash, G (Indian Inst. Tech., Madras) et al.
The MALTA family of Depleted Monolithic Active Pixel Sensors (DMAPS) is produced using Tower 180 nm CMOS technology, specifically targeting radiation-hard applications in the HL-LHC and beyond. Several process modifications have resulted in radiation hardness up to ${3 \times 10^{15}~1 ~\text{MeV}~\text{n}_{\text{eq}} /\text{cm}^2}$ and time resolution below 2 ns, with uniform charge collection efficiency across the chip formed of $512 \times 224$ pixels with a size of $36.4 \times 36.4~\mu\text{m}^2$.

The MALTA silicon pixel detector combines a depleted monolithic active pixel sensor (DMAPS) with a fully asynchronous front-end and readout. It features a high granularity pixel matrix with a 36.4 μm symmetric pixel pitch, low power consumption of <1 μW/pixel and low material budget with detector thicknesses as little as 50 μm. [...]
