The ALICE ITS3 project will be the first application of bent pixel sensors in high energy physics experiments. Combining truly cylindrical chips of unprecedented low material budget with the migration to a new process technology node that allows stitched sensors will pave the way to a nearly massless detector system. Understanding the effects that could potentially alter its performance is of...
The ALICE Inner Tracking System has been recently upgraded to a new version (ITS2), which is entirely based on Monolithic Active Pixel Sensors (MAPS). For a future upgraded tracker, the ITS3, it is intended to replace the three innermost layers of the current ITS2 to further improve its vertexing capabilities. The proposed design features wafer-scale, ultra-thin, truly cylindrical MAPS. In...
The implementation of new detector technologies is mandatory to continue the rapid evolution of High Energy Physics Experiments. The goal of the TANGERINE project is to develop the next generation of monolithic silicon pixel detectors using a 65 nm CMOS imaging process, which offers a higher logic density and overall lower power consumption compared to previously used processes. One objective...
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 × 1034 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 proposed changes is...
A new application for monolithic pixel detectors is NASA’s AMEGO-X project, which is a low-orbit gamma ray observatory for multimessenger astrophysics, planned as a 3 to 5 year mission set to take off in 2028. For the 40-layer Compton camera, 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...
The rising demand for fast particle detectors able to handle the increasing luminosity in High Energy Physics (HEP) experiments has led to the development of a new family of silicon detectors, namely Low Gain Avalanche Detectors (LGADs). Due to their low material budget and excellent 4D-tracking capabilities, i.e. the simultaneous measurement of the particle‘s position and time with high...
In recent years, the measurement of the time-of-flight (TOF) of charged particles has been identified as opportunity for particle identification (PID) at the future Higgs factories (FHF) currently under discussion by the international community, including the recently updated European Strategy for Particle Physics. TOF would in particular allow to identify charged hadrons at low momenta,...
Silicon Photomultipliers (SiPMs) offer high gain (typically 10^5 to 10^6) and a large dynamic range from single photons to up to several 10 000 photons at low bias voltages. They consist of single-photon avalanche diodes (SPADs) operated in Geiger mode. The small size of the SiPMs compared to conventional PMTs allows much higher integration levels of the front-end electronics. Therefore, SiPMs...
Radiotherapy is an important method in treatment of tumors. The most commonly used radiotherapy is X-ray and gamma radiation. More recently, irradiation with heavy ionized particles – such as protons and carbon ions – have been introduced clinically. The source of these particles is a particle accelerator. In contrast to X-ray and gamma radiation, ions and protons depose energy close to the...
MALTA is a depleted monolithic active pixel sensor developed in the Tower 180 nm CMOS imaging process.
Monolithic CMOS sensors offer advantages over current hybrid imaging sensors both in terms of increased
tracking performance due to lower material budget but also in terms of ease of integration and construction
costs due to the integration of read-out and active sensor into one chip....
The "Pixelated Energy Resolving CMOS Imager, Versatile And Large" (PERCIVAL) is a monolithic CMOS active pixel sensor for soft X-rays in synchrotron rings and free-electron lasers. The first back-illuminated full-size sensor, P2M, has a large continuous sensitive area of 4 cm x 4 cm (1408 x 1484 pixels of 27 um x 27 um) and has been applied to user experiments at FLASH and Petra III. A new...
Currently the landscape of Synchrotron Radiation sources is experiencing a major change by planned or ongoing machine upgrades: Most storage rings reach the diffraction limit, causing an expected increase in brilliance by about two orders of magnitude. Most FEL1 sources increase repetition rates to around 100kHz. This also holds true for the European XFEL2, where a change from the train mode...
There is a growing need for large area X-ray sensors. The next generation of X-ray sensors will be oriented towards digital imaging by making use of semiconductor materials with direct conversion at high efficiency so-called High-Z materials. Up to now, the production of large area sensors based on highly efficient semiconductors is limited. These limitations are related to growth process and...
