We present a novel single-photon detector based on a vacuum tube incorporating a photocathode, a microchannel plate (MCP), and a Timepix4 CMOS ASIC functioning as a pixelated anode. Designed to handle photon rates up to 1 billion per second across a $7$ $\text{cm}^2$ active area, the detector achieves outstanding spatial and temporal resolutions of $5 - 10$ $\mu\text{m}$ and below $50$ $\text{ps}$ r.m.s., respectively.

Timing performance of the DESY ER1 chip in a 65 nm CMOS imaging technology
/ He, Yajun (DESY) ; Ballabriga Sune, Rafael (DESY) ; Buschmann, Eric (Brookhaven Natl. Lab.) ; Campell, Michael (CERN) ; Mohr, Raimon Casanova (Barcelona, IFAE) ; Chauhan, Ankur (DESY) ; Dannheim, Dominik (CERN) ; Del Rio Viera, Manuel Alejandro (DESY) ; Dilg, Jona (DESY) ; Dorda, Ana (CERN) et al.
Monolithic active pixel sensors (MAPS) are promising candidates for the next generation of vertex detectors at future lepton colliders. One particularly interesting advancement is the recently accessible 65 nm CMOS imaging technology, which offers higher logic density compared to larger feature-size processes, making it highly appealing to the High Energy Physics community.

Probability distribution maps of deposited energy with sub-pixel resolution for Timepix3 detectors

The Medipix3 Collaboration has developed the Timepix3 chip, which can provide information about individual particles interacting with a hybrid pixelated semiconductor detector.The Timepix3 generates a data packet including time and energy information for each pixel receiving a charge above the discriminator threshold. From a set of such packages generated by one particle the total deposited energy and the sub-pixel center of mass (c.m) position of the interaction can be calculated. [...]

A Sensor Employing an Array of Silicon Photomultipliers for Detection of keV Ions in Time-of-Flight Mass Spectrometry
/ Mariscal-Castilla, Antonio (Barcelona U.) ; Piller, Markus (CERN) ; Alozy, Jerome (CERN) ; Ballabriga, Rafael (CERN) ; Campbell, Michael (CERN) ; de la Torre, Oscar (Barcelona U.) ; Gascón, David (Barcelona U.) ; Gómez, Sergio (Barcelona, Polytechnic U.) ; Heathcote, David (Oxford U.) ; Mauricio, Joan (Barcelona U.) et al.
Pixellated scintillation detectors have the potential to overcome several limitations of conventional microchannel-plate-based detectors employed in time-of-flight mass spectrometry (ToF-MS), such as extending detector lifetime, reducing vacuum requirements, or increasing the ion throughput. We have developed a prototype comprising a fast organic scintillator (Exalite 404) coupled to an array of 16 silicon photomultipliers (SiPMs), with read-out electronics based on the FastIC application-specific integrated circuit (ASIC).

The Picosec MicroMegas collaboration aims to develop gaseous fast-timing detectors; experimentally, intrinsic time resolutions from around 50ps to better than 20ps are obtained, depending on the exact detector configuration. Parts of developments focus on exploring various options of fast-timing multi-channel front-end electronics, to meet the data processing demands of experimental applications. [...]
