First results on new helium based eco-gas mixtures for the Extreme Energy Events Project
/ EEE Collaboration
The Extreme Energy Events (EEE) Project, a joint project of the Centro Fermi (Museo Storico della Fisica e Centro Studi e Ricerche "E.Fermi") and INFN, has a dual purpose: a scientific research program on cosmic rays at ground level and an intense outreach and educational program. The project consists in a network of about 60 tracking detectors, called telescopes, mostly hosted in Italian High Schools. [...]

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..

/ Abbrescia, M (Bari U. ; INFN, Bari) ; Avanzini, C (INFN, Pisa ; Pisa U.) ; Baldini, L (INFN, Pisa ; Pisa U.) ; Ferroli, R Baldini (Frascati) ; Batignani, G (INFN, Pisa ; Pisa U.) ; Battaglieri, M (INFN, Genoa) ; Boi, S (Cagliari U. ; INFN, Cagliari) ; Bossini, E (INFN, Pisa ; Pisa U.) ; Carnesecchi, F (CERN) ; Casula, M (Turin, Cosmo-Geofisica Lab) et al.
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.

Understanding the direct detection of charged particles with SiPMs

In this paper evidence that the increased response of SiPM sensors to the passage of charged particles is related mainly to Cherenkov light produced in the protection layer is reported. The response and timing properties of sensors with different protection layers have been studied..

Measurements of the Cherenkov effect in direct detection of charged particles with SiPMs
/ Carnesecchi, F. (CERN) ; Sabiu, B. (Bologna U. ; INFN, Bologna) ; Strazzi, S. (Bologna U. ; INFN, Bologna) ; Vignola, G. (INFN, Bologna) ; Agrawal, N. (Bologna U. ; INFN, Bologna) ; Alici, A.

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.

The new LUCID-2 detector for luminosity measurement and monitoring in ATLAS
/ Avoni, G (INFN, Bologna ; Bologna U.) ; Bruschi, M (INFN, Bologna) ; Cabras, G (INFN, Bologna ; Bologna U.) ; Caforio, D (IEAP CTU, Prague) ; Dehghanian, N (Alberta U.) ; Floderus, A (Lund U.) ; Giacobbe, B (INFN, Bologna) ; Giannuzzi, F (INFN, Bologna ; Bologna U.) ; Giorgi, F (INFN, Bologna ; Bologna U.) ; Grafström, P (INFN, Bologna ; Bologna U.) et al.
The ATLAS luminosity monitor, LUCID (LUminosity Cherenkov Integrating Detector), had to be upgraded for the second run of the LHC accelerator that started in spring 2015. The increased energy of the proton beams and the higher luminosity required a redesign of LUCID to cope with the more demanding conditions. [...]
