The upgrade of the ATLAS tracking detector (ITk) for High-Luminosity Large Hadron Collider at CERN requires development novel radiation hard silicon sensor technologies. Latest developments in CMOS processing offer possibility combining high-resistivity substrates with on-chip high-voltage biasing to achieve a large depleted active volume. We have characterised monolithic pixel sensors (DMAPS), which were produced modified imaging process implemented TowerJazz 180 nm framework ALICE...
The ATLAS collaboration is currently investigating CMOS monolithic pixel sensors for the outermost layer of upgrade its Inner Tracker (ITk). For this application, two large scale prototypes featuring small collection electrode have been produced in a radiation-hard process modification standard 0.18 μm imaging technology: MALTA, with novel asynchronous readout, and TJ MONOPIX, based on well established "column-drain" architecture. MALTA chip first full-scale prototype suitable development...
Depleted monolithic active pixel sensors (DMAPS), which exploit high voltage and/or resistivity add-ons of modern CMOS technologies to achieve substantial depletion in the sensing volume, have proven radiation tolerance towards requirements ATLAS high-luminosity LHC era. DMAPS integrating fast readout architectures are currently being developed as promising candidates for outer layers future Inner Tracker, will be installed during phase II upgrade around year 2025. In this work, two...
Depleted Monolithic Active Pixel Sensors (DMAPS) are an option for the outermost layer of upgraded ATLAS ITk Detector at CERN LHC. Two large size DMAPS named TJ MALTA and Monopix were produced in TowerJazz 180 nm CMOS imaging process a small collection electrode design. The chip combines low power front end with novel matrix readout design to achieve consumption <80 mW/cm2. Threshold values 250 e- dispersion 30 ENC < 10e- can be achieved before irradiation which is consistent results from...
The ATLAS experiment is planning a major upgrade of its tracking detectors, both strip and pixel, to take full advantage the High Luminosity LHC. A novel Monolithic Active Pixel Sensor based on 180 nm TowerJazz CMOS imaging technology, dubbed MALTA, has been designed meet radiation hardness requirements (1.5x10$^{15}$ 1 MeV $n_{eq}$/cm$^{2}$) outer barrel layers ITk detector. MALTA combines low noise (ENC<20 e$^{-}$) power operation (1 $\mu$W/pixel) with fast signal response (25 ns bunch...
This is a short conference record (a detailed article will be submitted for peer-reviewed publication after the project gather first data) about iMPACT project, which aims to build novel pCT scanner protons of medical energy (200-300 MeV range) designed improve current state art in tracking at all levels: speed, spatial resolution and material budget. Scanning time limited few seconds, budget reduced by factor 4 (respect micro-strip based detectors) pushed down 10 μm range mark. Such...
The upgrade of the ATLAS tracking detector for High-Luminosity Large Hadron Collider at CERN requires development novel radiation hard silicon sensor technologies. For de- velopment depleted CMOS sensors we combined small electrodes with minimal capacitance and advanced processing fully active volume to achieve in line ITk specifications. Based on initial studies prototype “TowerJazz Investigator” have now developed, produced tested a first full-size based 180nm TowerJazz imag- ing process,...
