The MONOLITH ERC Advanced project aims at producing a monolithic silicon pixel ASIC with 50 µm 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 continuous gain layer...
The CERN RD50 collaboration developed several radiation-hard monolithic silicon
particle detectors (DMAPS) to study their usability for tracking and vertexing. The
most recent development is the so-called RD50-MPW3.
This sensor was fabricated in a 150nm High Voltage CMOS process by LFoundry and
consists of 64 × 64 pixel with a pitch of 62μm. Besides an analog front end, the...
The ALICE experiment is preparing the ITS3, an upgrade of its Inner Tracking System for LHC Run 4.
The technology proposed for this upgrade is Monolithic Active Pixel Sensor (MAPS) produced in the 65 nm CMOS imaging process by TPSCo. Different pixel test structures have been developed to validate this technology. One of these is the Analogue Pixel Test Structure (APTS) which features an...
Sensor samples for a future compact electromagnetic sampling calorimeter were tested in DESY-II electron beam in 2021 and 2022. The sensors are made of silicon and GaAs with the size of 5$\times$8 cm$^2$. They are 320 µm and 500 µm for the silicon and GaAs sensors in thickness, respectively, and the pad size is 5$\times$5 mm$^2$. The compactness of the sampling calorimeter requires the readout...
Silicon-based sensors that can deliver a timing resolution of a few tens of ps along with a significantly better spatial resolution (O(few μm)) have been studied extensively in recent years. In an AC-coupled Low-Gain Avalanche Diode (LGAD), a highly-doped p+ gain layer is implanted between a continuous n+ layer and p-type bulk to form a high-field multiplication region. Electrical signals in...
The excellent performance of bent ALPIDE sensors has been demonstrated within the ALICE ITS3 R&D. In the corresponding analysis effort a need for simulation and reconstruction software capable of accurately handling bent sensors emerged. The Corryvreckan framework is being updated to include the ability to model bent sensor geometries, providing an important tool for bent pixel sensor beam...
