“…This hybrid tracker, called Mighty Tracker, will combine scintillating fibres in the outer regions and silicon sensors in the inner regions, where the hit density and radiation damage are highest. For the silicon region, a new high voltage complementary metal-oxidesemiconductor (HV-CMOS) pixel chip [3,4], MightyPix, is being developed, based on knowledge of previous HV-CMOS sensors, ATLASPix and MuPix [5].…”

MightyPix is a high voltage complementary metal-oxide-semiconductor (HV-CMOS) active pixel sensor, currently being developed for the Mighty Tracker, an upgrade proposed for LHCb in anticipation of the High Luminosity LHC. To ensure that MightyPix will be able to handle the particle hit rates at the Mighty Tracker, which are expected to reach 17 MHz/cm2, simulations of the chip's digital readout mechanism were performed. Using simulated particle hits the chip's performance within the LHCb environment is characterised. For this, a behavioural model of the first prototype, MightyPix1, representing the analogue pixel matrix, together with the synthesised digital logic is used. Simulation results show the MightyPix1 readout mechanism having an efficiency over 99 % up to 20 MHz/cm2. The bottleneck was found to be the speed at which the hits are read out. This yielded new design ideas to improve the readout for MightyPix2, leading to an efficiency of over 99 % up to 30 MHz/cm2.

“…The AstroPix project aims to develop and test pixelated silicon sensors for use in space-based gamma-ray instruments. This novel space-based technology is based upon work done with similar detectors at the Large Hadron Collider [8], and could contribute to a host of future instruments such as a next-generation wide-field gamma-ray explorer whose time domain capabilities is prioritized in the Astro2020 Decadal Survey [6]. This work will overview the design, testing, and development of AstroPix version 2.…”

Space-based gamma-ray telescopes such as the Fermi Large Area Telescope have used single sided silicon strip detectors to measure the position of charged particles produced by incident gamma rays with high resolution. At energies in the Compton regime and below, two dimensional position information within a single detector is required. Double sided silicon strip detectors are one option; however, this technology is difficult to fabricate and large arrays are susceptible to noise. This work outlines the development and implementation of monolithic CMOS active pixel silicon sensors, AstroPix, for use in future gamma-ray telescopes. Based upon detectors designed using the HVCMOS process at the Karlsruhe Institute of Technology, AstroPix has the potential to maintain the high energy and angular resolution required of a medium-energy gammaray telescope while reducing noise with the dual detection-and-readout capabilities of a CMOS chip. The status of AstroPix development and testing as well as outlook for application in future telescopes is presented.

The All-sky Medium Energy Gamma-ray Observatory eXplorer (AMEGO-X) is designed to identify and characterize gamma rays from extreme explosions and accelerators. The main science themes include supermassive black holes and their connections to neutrinos and cosmic rays; binary neutron star mergers and the relativistic jets they produce; cosmic ray particle acceleration sources including galactic supernovae; continuous monitoring of other astrophysical events and sources over the full sky in this important energy range. AMEGO-X will probe the medium energy gamma-ray band using a single instrument with sensitivity up to an order of magnitude greater than previous telescopes in the energy range 100 keV to 1 GeV that can be only realized in space. During its 3-year baseline mission, AMEGO-X will observe nearly the entire sky every two orbits, building up a sensitive all-sky map of gamma-ray sources and emissions. AMEGO-X was submitted in the recent 2021 NASA MIDEX announcement of opportunity.
