Thermonuclear fusion in the laboratory is a scientific grand challenge, a highly compelling problem because the fusion reactions can self-heat the fuel and continue the burn. Predominantly approaches use the fusion of deuterium and tritium nuclei, which generates 17.6 MeV of energy released in a neutron and alpha particle. The alpha particle which carries
1/5 of the energy can heat the...
Optimization of the timing resolution in the scintillation light readout has been one of the most important challenges in the SiPM field since the beginning of their development. Several sensor parameters contribute to the timing performance achieved in the application. The latest iteration of the NUV-HD SiPM technology developed at FBK feature Photon Detection Efficiency (PDE) in excess of...
Radiation damage mechanisms in depleted sensors with intrinsic gain (LGADs) are probed via electrical characterization, timing measurements and accceptor removal estimation. An analytical model is developed to prove gain vs field coefficients in proton and neutron irradiated sensors up to 6e15 $n_{eq}/cm^{2}$ with an emphasis on the gain layer geometry. The breakdown, efficiency and stability...
We first describe the development of a fast readout system of an LGAD detector using the waveform technique. We use this detector to measure the type of particles and their energy in cosmic ray measurements in space in collaboration with NASA. We will show the results of the simulation of the detectors as well as the first tests performed before the launch foreseen by the end of the year. We...
Positron Emission Tomography (PET) is a unique medical imaging modality that can detect the specific chemical tracers within the patient body and is used every day in clinics to detect cancers. Recently developed time-of-flight PET uses arrival timings of the annihilation photon pairs to increase the image quality. Conventional scintillation-based detection, however, poses limits to the...
Heavy inorganic scintillators, such as LYSO:Ce, is currently used to construct the CMS Barrel Timing Layer aiming at 30 ps time resolution for the HL-LHC. Ultrafast inorganic scintillators, such as BAF2:Y, has been proposed for ultrafast calorimeter and GHz hard X-ray imaging. In this investigation, we report temporal response of ultrafast inorganic scintillators with ultrafast decay time,...
The advent of x-ray free electron lasers (XFELs) has enabled us to peer into dynamic extreme conditions with unprecedented spatial and temporal resolution. Imaging with these sources has enabled movies of femtosecond to nanosecond dynamics in plasma, planetary and shock physics. Additionally, the high spatial and temporal coherence of XFELs can enable reconstruction of areal densities of the...
Nozzle geometry features directly impact the nozzle internal flow which significantly affects the spray atomization, as well as in-cylinder combustion and fuel economy. In this study, the nozzle internal transient flow was visualized through X-ray phase-contrast imaging technology. The experimental results indicated that the sac-orifice relative positions and the structural asymmetry of the...
Gotthard-II (G-II) is a silicon microstrip hybrid detector developed by Paul Scherrer Institut (PSI) within the framework of a collaboration agreement with the European XFEL (EuXFEL).
The G-II ASIC features a dynamic gain switching (DGS) architecture to cope with the requirements of the single photon sensitivity as well as the large dynamic range at the EuXFEL. In addition, it includes a...
The design of a billion-pixel X-ray camera (BiPC-X) is based on the tiling of several CMOS sensors, each having a few million pixels. Both direct low-energy (< 10 keV) and indirect higher energy detection (> 20 keV) are possible, where the camera can achieve frame rates of 1 MHz and possibly higher depending on the settings [1].
With an image size of a billion pixels, the camera generates a...

New materials will define tomorrow’s technologies. They are part of a materials multiverse where every crystal provides a unique framework to define a new state of matter – some more exotic than others. Notions of topology have provided a new paradigm for understanding some of these new phases of matter and have exciting physical consequences, such as protected surface states and magnetic...
Dielectric-loaded waveguide detectors that measure microwave Cherenkov signals can be used to time and characterize high energy particle showers. Beam test results have been used to validate models and produce high-fidelity simulations of timing plane systems which yield picosecond time tags and millimeter spatial coordinates for shower centroids. These timing planes, based on the Askaryan...
The FASER experiment at the LHC is designed to look for new, long-lived fundamental particles. To extend its discovery potential, a W-Si preshower detector is currently under construction, with the objective of enabling the discrimination of photon pairs with O(TeV) energies and separation down to 200 µm. The detector will be based on a new monolithic silicon pixel sensor in 130nm SiGe BiCMOS...
