/ Bossini, E (Pisa U. ; INFN, Pisa) ; Abbrescia, M (Bari Polytechnic ; INFN, Bari ; Bari U.) ; Avanzini, C (INFN, Pisa ; Pisa U.) ; Baldini, L (Pisa U. ; INFN, Pisa) ; Ferroli, R Baldini (Frascati) ; Batignani, G (Pisa U. ; INFN, Pisa) ; Battaglieri, M (INFN, Genoa) ; Boi, S (Cagliari U. ; INFN, Cagliari) ; Carnesecchi, F (CERN) ; Cavazza, F (INFN, Bologna) et al.
The Extreme Energy Events (EEE) experiment, a joint project of the Centro Fermi and INFN Italian national research institutes, has a dual purpose: a scientific research program for measurements of the cosmic rays flux at ground level and an intense outreach and educational program with an active contribution of students and teachers in the construction and operation of the detectors in High Schools. The network counts 60 tracking detectors, each made by three Multigap Resistive Plate Chambers (MRPC), operated so far with a gas mixture composed by 98% C$_2$H$_2$F$_4$ and 2% SF$_6$. [...]

An Inertial Uni-Axial Interferometer-Based Accelerometer for Harsh Environments
/ Aliana Cervera, Gerard (CERN ; Ecole Polytechnique, Lausanne) ; Solis Paiva, Santiago Andres (CERN) ; Serrano Galvez, Pablo (CERN) ; Sola Merino, Jorge (CERN) ; Butcher, Mark (CERN) ; Matheson, Eloise (CERN) ; di Castro, Mario (CERN)
For high-impact devices, subsequent vibrations
have as much influence on the deterioration of the mechanical
structure as the impact itself. To mitigate the consequences
of both impacts and resulting vibrations, it is crucial to
accurately understand the peak acceleration and vibration
frequencies that originate in the structure. [...]

EULIMA Beam Delivery
/ Farley, F.J.M. (CAL, Nice) ; Carli, C. (CERN)
The beam delivery system planned for EULIMA will use a small spot which will be scanned over the tumour volume. The spot will be sufficiently small that the edge can be defined sharplyenough without adding collimators. [...]

The PICOSEC Micromegas detector is a precise timing gaseous detector based on a Cherenkov radiator coupled to a semi-transparent photocathode and a Micromegas amplifying structure. First single-pad prototypes demonstrated a time resolution below 𝜎 = 25 ps, however, to make the concept appropriate to physics applications, several developments are required. [...]
