Cosmic-ray muon scattering tomography (MST) recovers the inverse radiation length λ ( r ) = 1 / X 0 ( r ) of dense or shielded objects, but classical algorithms (PoCA, MLEM) discretise the volume into a fixed voxel grid and become noise-limited at fine resolution. We introduce MINT (Muon Implicit Neural Tomography), a differentiable neural-field framework that represents λ by a coordinate-based n…

During the production of the new ATLAS18 Inner-Tracker strip sensors for the forthcoming High-Luminosity Large Hadron Collider upgrade, the collaboration observed indications of low p-stop doping in a few sensor batches. Detailed studies of Quality Assurance test structures, such as MOS capacitors with p-stop or Punch-Through Protection structures, showed deviations of parameters dependent on the…

This study examines the light yield non-proportionality of Lu 1.8 Y 0.2 SiO 5 :Ce 3+ (LYSO:Ce), Lu 3 Al 5 O 12 :Ce 3+ (LuAG:Ce), (Gd,Lu) 3 (Al,Ga) 5 O 12 :Ce 3+ (GLuGAG:Ce), and LaBr 3 :Ce 3+ (LaBr 3 :Ce) to low energy electrons. The intrinsic radiation of these scintillators makes the study of the light yield, implementing the conventional Compton coincidence technique, a difficult task. In this…

This paper presents the development of a CMOS-based pixel readout architecture in a 55 nm HV-CMOS process, targeting the high-hit-density ( > 100 MHz/ cm 2 ) and nanosecond-level timing requirements of the LHCb Upgrade II Upstream Tracker. The architecture is implemented in the COFFEE3 prototype. Each pixel (40 µm × 145 µm) integrates a charge-sensitive amplifier, discriminator, threshold-tuning …

The dual neutron/gamma-ray sensitivity of organic scintillators makes them suitable for a wide range of nuclear measurement applications, including nuclear nonproliferation, nuclear medicine, and fundamental physics. Pulse shape discrimination techniques enable distinguishing interactions of different particle types and are typically implemented with simple analog techniques or digital renditions…
