First experimental results of the spatial resolution of RSD pad arrays read out with a 16-ch board
Resistive Silicon Detectors (RSD, also known as AC-LGAD) are innovative silicon sensors, based on the LGAD technology, characterized by a continuous gain layer that spreads across the whole sensor active area. RSDs are very promising tracking detectors, thanks to the combination of the built-in signal sharing with the internal charge multiplication, which allows large signals to be seen over multiple read-out channels. This work presents the first experimental results obtained from a 34 array with 200~\mum~pitch, coming from the RSD2 production manufactured by FBK, read out with a 16-ch digitizer. A machine learning model has been trained, with experimental data taken with a precise TCT laser setup, and then used to predict the laser shot positions, finding a spatial resolution of ~ 5.5 um

Silicon Sensors for Future Particle Trackers
Several future high-energy physics facilities are currently being planned.
The proposed projects include high energy circular and linear
colliders, hadron colliders and muon colliders, while the Electron-Ion Collider
(EIC) has already been approved for construction at the Brookhaven National
Laboratory. Each proposal has its own advantages and disadvantages in term of
readiness, cost, schedule and physics reach, and each proposal requires the
design and production of specific new detectors. This paper first presents the
performances required to the future silicon tracking systems at the various new
facilities, and then it illustrates a few possibilities for the realization of
such silicon trackers. The challenges posed by the future facilities require a
new family of silicon detectors, where features such as impact ionization,
radiation damage saturation, charge sharing, and analog readout are exploited
to meet these new demands
