Hybrid pixel detectors (HPD) of Timepix [1,2] technology have become increasingly interesting for space applications. While up to date, common space radiation monitors rely on silicon diodes, achieving particle (mainly electron and proton) separation by pulse-height analysis, detector stacking, shielding or electron removal by a magnetic field, the key advantage of HPDs is that, in addition to...

We present a spectroscopic detection module with position sensitivity based on the largest monolithic array of Silicon Drift Detectors (SDD) ever reported. It consists of 166 pixels of 3 mm diameter with integrated JFET. This module has been developed within the TRISTAN project, aiming at investigating the existence of the sterile neutrino in the keV mass range by beta spectroscopy [1]. The...

The DSSC camera [1] was developed for photon science applications in the energy range 0.25-6 keV at the European XFEL in Germany. The first 1-Megapixel DSSC camera is available and is successfully used for scientific experiments at the โSpectroscopy and Coherent Scatteringโ and the โSmall Quantum Systemโ instruments. The detector is currently the fastest existing 2D camera for soft...

A novel design of the Depleted P-Channel Field Effect Transistor (DEPFET) with non-linear response is at the heart of the 1 Mpixel DSSC camera (DEPFET Sensor with Signal Compression) currently being developed for ultra-fast imaging of soft X-rays at the European XFEL. The simultaneous requirement of single-photon detection down to 0.5 keV and dynamic range up to 104 photons/pixel/pulse is here...

Silicon Photomultipliers (SiPMs) are Geiger-mode photodetectors largely used in scientific experiments of high energy physics as well as in medical imaging. Recently, SiPMs are also being considered the detectors of choice for autonomous driving based on light detection and ranging (LiDAR) systems [1].

Recent advances in THM growth and contact engineering of high-flux CdZnTe sensors have enabled dramatically improved hole mobility-lifetime product resolving historical problems with detector polarization. To illustrate superior performance of high-flux CZT we will show some experimental studies in Spectral Computed Tomography (SCT), High-Intensity X-Ray Imaging and Theranostics.

Gallium arsenide has noticeable advantages over silicon for radiation detector manufacturing. There is particularly a higher electron mobility (8000 vs 1400 cm2/(Vยทs)), bigger average atomic number (31.5 vs 14) and wider bandgap (1.43 vs 1.12 eV). These advantages result in a better charge collection, higher radiation absorption efficiency, superior radiation hardness and lower noise.
In...

In hard-X-ray applications that require high detection efficiency and short response times, III/V compound semiconductors offer some advantages over the Si-based technologies traditionally used in solid-state photodetectors. Amongst them, GaAs is one of the most valuable materials thanks to its outstanding properties. At the same time, implementing charge-multiplication mechanisms within the...

Neutron detection has historically been achieved using $^3$He or BF$_3$ gas detectors. The scarcity of $^3$He, and the toxicity of BF$_3$, have driven detector research into finding new solutions for efficient neutron detection. For applications in neutron imaging with thermal neutrons, planar silicon detectors coated with neutron converting materials ($^{10}$B and $^6$Li) have shown promising...

We present a novel scalable graphene-silicon hybrid photodiode that enables deep UV imaging. We have a created a photodiode with a reduced dead layer entrance window. Existing photodiodes are limited in sensitivity for low wavelengths due to the low penetration depth of photons of < 400 nm. Typical photodiodes have a junction implant which causes the low penetrating photons to be recombined in...

Soft X-ray applications at synchrotrons and FELs are limited by the performance of the currently available detectors using silicon sensors. The main issues are their low quantum efficiency (QE) due to the photon absorption in the entrance window of the sensor, and their difficulties in achieving single photon resolution, since the small amount of charge generated by the low energy X-rays is...

The ALICE experiment is planning next upgrade of the Inner Tracking System (ITS3) during the LHC Long Shutdown 3 (LS3) in 2025 โ 2028. The main aim of this upgrade is to reduce material budget of the three innermost layers from 0.3% X$_0$ to 0.05% X$_0$ per layer. Such a significant improvement is within the reach if segmented layers of the current detector would be replaced with truly...

The ARCADIA collaboration is developing fully-depleted (FD) Monolithic Active Pixel Sensors (MAPS) in a 110nm CMOS process in collaboration with LFoundry. The sensor design incorporates an n+ collection node within a highly doped n-type epi-layer on top of a n-type substrate and p+ backside. Thus, the pn-junction sits on the backside and through an applied backside bias, the full substrate...

Collider experiments as the upcoming Phase II-LHC or the future circular collider (FCC) will increase the demands of the detectors used for tracking. In the FCC hadron collider , sensors will not only face fluences up to to $1ร10^{17}~ n_\mathrm{eq}/\mathrm{cm}^2$, but also high pile-up scenarios. Therefore, sensors will be required that not only have a good spatial resolution and a very high...
