Silicon tracker sensors R&D is aiming at the improvement of the position and timing resolution. Instead of scaling down pitch sizes, which comes at a high price for an increased number of channels, our new sensor concept seeks to improve the position resolution by increasing the lateral size of the charge distribution already during the drift in the sensor material. To this end, it is...

We carried out several...
Considerable experimental and theoretical work has been devoted to solving the Dark Matter (DM) puzzle. However, apart from gravitational evidence, no other measurements confirm DM existence. Weakly Interacting Massive Particles (WIMPs) are perhaps the most broadly accepted hypothesis postulated for DM. If true, the galaxies are immersed in a vast halo of WIMP particles moving at a different...

The foreseen replacement of the inner fibre mat modules during the next long shutdown (2025 - 2027) requires to...
The saturated avalanche discharge regime led to an increase in term of detection rate capability, allowing RPC to be used in experiments on particle accelerators. Future experiments require even more extreme performance from particle detectors, in term of rate capability and time resolution, so that the saturated avalanche discharge is a limiting factor for the RPCs application.
In this...

Detection of gamma-ray polarization in Positron Emission Tomography (PET) is yet an unexploited feature that could be used as an additional handle to improve signal-to-background ratio in this imaging modality.
