On the wake of the results obtained so far at the SPARC\_LAB test-facility at the Laboratori Nazionali di Frascati (Italy), we are currently investigating the possibility to design and build a new multi-disciplinary user-facility, equipped with a soft X-ray Free Electron Laser (FEL) driven by a $\sim$1 GeV high brightness linac based on plasma accelerator modules. This design study is performed in synergy with the EuPRAXIA design study. [...]

(INFN, Bologna ; Bologna U., Dept. Astron.) ; Di Giovenale, D. (Frascati) ; Di Giulio, C. (Frascati) et al.
The light yield, the time resolution and the efficiency of different types of scintillating tiles with direct Silicon Photomultiplier readout and instrumented with a customised front-end electronics have been measured at the Beam Test Facility of Laboratori Nazionali di Frascati and several test stands. The results obtained with different configurations are presented. [...]

The present work is focused on the characterization of a
Timepix3 (TPX3) based test system for the identification of
particles produced by the complex decay chain of $^{222}$Rn. The
detector used is composed of a pixelated Cadmium Telluride (CdTe)
semiconductor (500 μm thick) bump-bonded on an ASIC TPX3
chip. [...]

(Frascati) ; Di Matteo, S. (Rennes U.) et al.
High-precision experiments have been done to test the Pauli exclusion principle (PEP) for electrons by searching for anomalous $K$-series X-rays from a Cu target supplied with electric current. With the highest sensitivity, the VIP (VIolation of Pauli Exclusion Principle) experiment set an upper limit at the level of $10^{-29}$ for the probability that an external electron captured by a Cu atom can make the transition from the 2$p$ state to a 1$s$ state already occupied by two electrons.

Negative Ion Time Projection Chamber operation with SF$_6$ at nearly atmospheric pressure
/ Baracchini, E. (Frascati ; INFN, Rome ; Rome U.) ; Cavoto, G. (INFN, Rome ; Rome U.) ; Mazzitelli, G. (Frascati) ; Murtas, F. (Frascati ; CERN) ; Renga, F. (INFN, Rome ; Rome U.) ; Tomassini, S. (Frascati)
We present measurements of drift velocities and mobilities of some innovative negative ion gas mixtures at nearly atmospheric pressure based on SF$_{6}$ as electronegative capture agent and of pure SF$_{6}$ at various pressures, performed with the NITEC detector. NITEC is a Time Projection Chamber with 5 cm drift distance readout by a GEMPix, a triple thin GEMs coupled to a Quad-Timepix chip, directly sensitive to the deposited charge on each of the 55 $\times$ 55 $\mu$m$^2$ pixel.

On the space resolution of the μ-RWELL
/ Bencivenni, G. (Frascati) ; Capoccia, C. (Frascati) ; Cibinetto, G. (INFN, Ferrara) ; de Oliveira, R. (CERN) ; Farinelli, R. (INFN, Ferrara) ; Felici, G. (Frascati) ; Gatta, M.

In MPGD detectors evaluation of the space resolution with the charge centroid (CC) method provides large uncertainty when the impinging particle is not perpendicular to the readout plane. An improvement of the position reconstruction, and thus of the space resolution, is represented by the $\mu$TPC algorithm. [...]
