(Trento U. ; INFN, Trento) et al.
In this paper we report on a set of characterisations carried out on the first monolithic LGAD prototype integrated in a customised 110 nm CMOS process having a depleted active volume thickness of 48 $\mu$m. This prototype is formed by a pixel array where each pixel has a total size of 100 $\mu$m $\times$ 250 $\mu$m and includes a high-speed front-end amplifier. [...]

A new Low Gain Avalanche Diode concept: the double-LGAD
/ Carnesecchi, F. (CERN) ; Strazzi, S. (INFN, Bologna ; U. Bologna, DIFA) ; Alici, A. (INFN, Bologna ; U. Bologna, DIFA) ; Arcidiacono, R. (INFN, Turin ; Piemonte Orientale U., Alessandria) ; Cartiglia, N. (INFN, Turin) ; Cavazza, D. (INFN, Bologna) ; Durando, S. (INFN, Turin ; Turin Polytechnic) ; Ferrero, M. (INFN, Turin) ; Margotti, A. (INFN, Bologna) ; Menzio, L. (INFN, Turin ; Turin U.) et al.
This paper describes the new concept of the double-LGAD. The goal is to increase the charge at the input of the electronics, keeping a time resolution equal or better than a standard (single) LGAD; this has been realized by adding the charges of two coupled LGADs while still using a single front-end electronics.

In this paper, different Silicon PhotoMultiplier (SiPM) sensors have been tested with charged particles to characterize the Cherenkov light produced in the sensor protection layer. A careful position scan of the SiPM response has been performed with different prototypes, confirming the large number of firing cells and proving almost full efficiency, with the SiPM filling factor essentially negligible.

After its successful campaign of measurements beyond the Polar Arctic Circle, the PolarquEEEst experiment measured the cosmic charged particle rate at sea level in a latitude interval between 35$^{\circ }$ N and 82$^{\circ }$ N. In this paper, these measurements are described and the corresponding results are discussed..

This paper presents the measurements on first very thin Ultra Fast Silicon Detectors (UFSDs) produced by Fondazione Bruno Kessler; the data have been collected in a beam test setup at the CERN PS, using beam with a momentum of 12 GeV/c. UFSDs with a nominal thickness of 25 $\mu$m and 35 $\mu$m and an area of 1 $\times$ 1 $\text{mm}^2$ have been considered, together with an additional HPK 50-$\mu$m thick sensor, taken as reference.

The eruption of the Hunga-Tonga volcano in the South Pacific Ocean on January 15, 2022, at about 4:15 UTC, generated a violent explosion, which created atmospheric pressure disturbances in the form of Rayleigh-Lamb waves detected all over the globe. Here we discuss the observation of the Hunga-Tonga shock-wave performed at the Ny-Ålesund Research Station on the Spitsbergen island, by the detectors of the PolarquEEEst experiment and their ancillary sensors.
