Timing with pixels

Correlations of photons from entangled quantum sources offer advantages and provide additional opportunities such as low light imaging or new sensing approaches. In general, strong spectro-temporal correlations inherent for entangled photons make those sensing techniques much more precise and resource efficient. To take advantage of the correlations one would need efficient single photon...
This contribution will report the first beam test results obtained coupling 450-micron pixel RSD sensors with the FAST3 ASIC. The sensors are part of the RSD2 FBK production, and FAST3 is the latest ASIC developed at INFN Torino for the read-out of thin sensors with internal gain. The results, obtained at the DESY testbeam site using 5 GeV electrons, demonstrate the possibility of concurrently...
Future experiments at high-luminosity hadron colliders will involve unprecedent levels of pile up, calling for precise time information at the pixel level to ease distinguishing between particle tracks. The unique geometry of 3D sensors enables to achieve very good timing performance, besides high radiation hardness. Remarkable results in terms of timing resolution have so far been reported...
High Energy Physics at future colliders demands a new generation of particle detectors with capabilities exceeding those of current silicon technology. For example, at the various $e^+e^-$ machines (CEPC, CLIC, FCC-ee, and ILC), the key requests are low material budget and excellent spatial resolution, with modest requests for radiation resistance or precise timing ($\sigma_t < 50$ ps). On the...
I. Introduction
The v1 and v2 MiniCACTUS sensors are monolithic CMOS sensors in LF15A technology, designed to investigate the possiblity of tagging time of arrival of Minimum Ionizing Particles with a resolution better than 100 ps. These sensors are a first step towards an ultimate time resolution of 20 ps, needed for future projects like FCC-ee. MiniCactus v1 and v2 feature arrays of...
The MONOLITH H2020 ERC Advanced project aims at producing a high-granularity monolithic silicon pixel detector with picosecond-level time stamping. Such extreme timing exploits: i) fast and low-noise SiGe BiCMOS electronics; ii) a novel sensor concept: the Picosecond Avalanche Detector (PicoAD), that uses a patented multi-PN junction to engineer the electric field and produce a continuous gain...
Charged Particle detection in High-Energy Physics (HEP) applications increasingly asks for sensors with improved timing resolution and low power. A trade-off between these two requirements is typically necessary and strongly linked to the design and technology of front-end readout electronics. Low-Gain Avalanche Detectors (LGADs), which have become an established technology in HEP experiments,...
Single Photon Avalanche Diodes (SPADs) have been recently introduced in process design kits of several CMOS foundries. This opens up possibilities to embed SPADs into custom CMOS ASICs, thus allowing for novel designs of monolithic silicon avalanche photo-detectors. A digital silicon photomultiplier (dSiPM) prototype with integrated readout was designed at DESY in the LFoundry 150 nm process...
A high rate beam telescope based on the Timepix4 ASIC has been built to evaluate novel pixel sensors with high spatial and temporal resolution. Moreover, the telescope can also be used for tests of synchronous multiple-detector readout and track reconstruction with fast timing capability (i.e. 4D tracking demonstrator).
The telescope consists of eight planes with n-on-p silicon sensors, each...
In recent years, development of pixel detectors has evolved from only improving the spatial resolution to also improving the temporal resolution. The ultimate goal is to develop a 4 Dimensional tracking (4D tracking) system capable of combining micrometer spatial resolution with a time resolution in the order of tens of picoseconds.
Low-Gain-Avalanche-Detectors (LGADs) provide a promising...
