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...
The ALICE ITS3 (Inner Tracking System 3) upgrade project together with the CERN EP R&D on monolithic sensors are exploring the Tower Partner Semiconductor Co. (TPSCo) 65 nm ISC process.
The ITS3 project aims to build the first fully cylindrical tracker by using wafer scale, ultra thin (20 - 40 μm) bent MAPS.
Four different pixel test structures, Circuit Exploratoire 65 (CE65), Digital Pixel...
In the coming years the Large Hadron Collider (LHC) at CERN is being upgraded to work at higher luminosities, leading to the High-Luminosity LHC. The HL-LHC will reach luminosities up to 5 × 10$^{34}$ cm$^{−2}$ s$^{−1}$ collecting at least 3000 fb$^{−1}$ of data in its lifetime. To handle the increased luminosity and data rate, the experiments at the LHC will be upgraded as well. One of the...
The goal for tracking detectors is the combination of excellent spatial resolution, low material budget, high radiation tolerance and excellent timing resolution for the best achievable tracking performance.
Many different approaches are taken to reach this goal, with CMOS based silicon detectors providing one of the most promising angles of approach.
The CERN RD50 collaboration works on...
The High Voltage CMOS (HV-CMOS) technology is a promising candidate for future particle physics experiments. To meet the needs of future experiments, especially in terms of single point resolution ($50 \times 50 \mathrm{\mu m^2}$), time resolution (0.2 ns) and radiation tolerance ($10^{16} \mathrm{n_{eq}/cm^2}$), the HV-CMOS pixel sensor performance needs to be further improved. The Liverpool...
The success of the Belle II experiment at KEK (Tsukuba, Japan) relies on the very high instantaneous luminosity expected from the SuperKEKB collider in the coming years, close to $6\times10^{35}\ \mathrm{cm}^{-2}\ \mathrm{s}^{-1}$. The beam conditions required to reach such luminosity cause a large rate of background particles to reach the innermost layers of the Belle II detector, which...
A new application for monolithic pixel detectors is NASA’s AMEGO-X project, which is a low-orbit gamma ray observatory for multimessenger astrophysics, proposed as a 3 to 5 year mission. For the 40-layer gamma-ray telescope, which will consist of over 64000 sensors with a total area of more than 25 m², a new low power and high dynamic range monolithic active pixel sensor named AstroPix is...
Silicon Photomultipliers (SiPMs) are well known as excellent light detectors in the ultraviolet to visible energy range with sub-nanosecond time resolution. Due to their unique characteristics, these detectors are widely used in high-energy physics and medical imaging systems. In conventional SiPMs, an array of Single Photon Avalanche Diodes (SPADs) is connected in parallel. In these devices...
MoTiC (Monolithic Timing Chip) is a prototype DMAPS Chip that builds on sensor technology developed in the ARCADIA project.
The 50 by 50$\mu$m$^2$ pixels contain a small charge collecting electrode with a very low capacitance surrounded by radiation-hard in-pixel electronics.
The chip contains a matrix of 5120 pixels on an area of 3.2 by 4 mm$^2$.
Each pixel features a trimmable and...
The MONOLITH ERC Advanced project aims at producing a monolithic silicon pixel ASIC with 50µm pixel pitch and picosecond-level time stamping. The two main ingredients are low-noise, fast SiGe BiCMOS electronics and a novel sensor concept, the Picosecond Avalanche Detector (PicoAD). The PicoAD uses a patented multi-PN junction to engineer the electric field and produce a continuous gain layer...
