Beam impact experiment of 440 GeV/p protons on superconducting wires and tapes in a cryogenic environment / Will, Andreas (KIT, Karlsruhe ; CERN) ; Bastian, Yan (CERN) ; Bernhard, Axel (KIT, Karlsruhe) ; Bonura, Marco (U. Geneva (main)) ; Bordini, Bernardo (CERN) ; Bortot, Lorenzo (CERN) ; Favre, Mathieu (CERN) ; Lindstrom, Bjorn (CERN) ; Mentink, Matthijs (CERN) ; Monteuuis, Arnaud (CERN) et al.
The superconducting magnets used in high energy particle accelerators such as CERN’s LHC can be impacted by the circulating beam in case of specific failure cases. This leads to interaction of the beam particles with the magnet components, like the superconducting coils, directly or via secondary particle showers. [...]

Shashlik calorimeters with embedded SiPMs for longitudinal segmentation / Berra, A (INFN, Milan Bicocca ; Insubria U., Varese) ; Brizzolari, C (INFN, Milan Bicocca ; Insubria U., Varese) ; Cecchini, S (INFN, Bologna) ; Chignoli, F (INFN, Milan Bicocca ; Milan Bicocca U.) ; Cindolo, F (INFN, Bologna) ; Collazuol, G (INFN, Padua) ; Delogu, C (INFN, Milan Bicocca ; Milan Bicocca U.) ; Gola, A (Fond. Bruno Kessler, Trento ; TIFPA-INFN, Trento) ; Jollet, C (Strasbourg, IPHC) ; Longhin, A (INFN, Padua) et al.
Effective longitudinal segmentation of shashlik calorimeters can be achieved taking advantage of the compactness and reliability of silicon photomultipliers. These photosensors can be embedded in the bulk of the calorimeter and are employed to design very compact shashlik modules that sample electromagnetic and hadronic showers every few radiation lengths.

The Large Hadron Collider forward (LHCf) experiment was motivated to understand the hadronic interaction processes relevant to cosmic-ray air shower development. We have developed radiation-hard detectors with the use of Gd$_2$SiO$_5$ (GSO) scintillators for proton-proton $\sqrt{s} = 13$ TeV collisions. [...]

Baby MIND: A magnetised spectrometer for the WAGASCI experiment / Hallsjö, Sven-Patrik (Glasgow U.) /Baby MIND
The WAGASCI experiment being built at the J-PARC neutrino beam line will measure the ratio of cross sections from neutrinos interacting with a water and scintillator targets, in order to constrain neutrino cross sections, essential for the T2K neutrino oscillation measurements. A prototype Magnetised Iron Neutrino Detector (MIND), called Baby MIND, has been constructed at CERN and will act as a magnetic spectrometer behind the main WAGASCI target. [...]

Novel Design features of the Baby MIND Detector for T59-WAGASCI experiment / Parsa, Saba (U. Geneva (main)) /Baby MIND
Baby MIND is a magnetized iron neutrino detector, planned to serve as a downstream magnetized muon spectrometer for the WAGASCI experiment, on the T2K neutrino beam line in Japan. Access restrictions in its intended location in Japan drove a completely new design of the magnetic modules, a departure from the traditional toroidal magnetized iron detectors such as CDHS and MINOS.

ENUBET: High Precision Neutrino Flux Measurements in Conventional Neutrino Beams / Pupilli, Fabio (INFN, Padua) ; Ballerini, G (Insubria U., Como ; INFN, Milan Bicocca) ; Berra, A (Insubria U., Como ; INFN, Milan Bicocca) ; Boanta, R (INFN, Milan Bicocca ; Milan Bicocca U.) ; Bonesini, M (INFN, Milan Bicocca) ; Brizzolari, C (Insubria U., Como ; INFN, Milan Bicocca) ; Brunetti, G (INFN, Padua) ; Calviani, M (CERN) ; Carturan, S (INFN, Legnaro) ; Catanesi, M G (INFN, Bari) et al.
The ENUBET project aims at demonstrating that the systematics in neutrino fluxes from conventional beams can be reduced to 1% by monitoring positrons from K$_{e3}$ decays in an instrumented decay tunnel, thus allowing a precise measurement of the $\nu_e$ (and $\overline{\nu}_e$) cross section. This contribution will report the results achieved in the first year of activities. [...]

A new detector exploiting the technology of Gas Electron Multipliers is under construction to replace the innermost drift chamber of BESIII experiment, since its efficiency is compromised owing the high luminosity of Beijing Electron Positron Collider. The new inner tracker with a cylindrical shape will deploy several new features. [...]

CaloCube: a new homogenous calorimeter with high-granularity for precise measurements of high-energy cosmic rays in space / Bigongiari, Gabriele (INFN, Pisa) /Calocube
The direct observation of high-energy cosmic rays, up to the PeV region, will depend on highly performing calorimeters, and the physics performance will be primarily determined by their acceptance and energy resolution.Thus, it is fundamental to optimize their geometrical design, granularity, and absorption depth, with respect to the total mass of the apparatus, probably the most important constraints for a space mission. Furthermore, a calorimeter based space experiment can provide not only flux measurements but also energy spectra and particle identification to overcome some of the limitations of ground-based experiments.

A low-cost Cherenkov detector to be tested in CERN's T9 beam line / Felici, Maria Rita (Unlisted, IT) ; Cameli, Luca (Unlisted, IT ; INFN, Rome) ; Camilli, Alessandro (Unlisted, IT) ; Castelli, Vanessa (Unlisted, IT) ; Catalini, Francesco (Unlisted, IT) ; Cipolletti, Samuele (Unlisted, IT) ; Crescenzi, Federico (Unlisted, IT) ; Decembrini, Niccolò (Unlisted, IT) ; De Paolis, Aurora (Unlisted, IT) ; Fattenotte, Francesco (Unlisted, IT) et al.
The TCO-Asa is a 2015 established team of high-school students of the Liceo Scientifico T. Calzecchi Onesti, in Fermo (Italy), who built a detector instrumented by consumer components including a CMOS camera and a silicon photomultiplier readout by the open-source ArduSiPM kit, to study the Cherenkov effect in water.This proceeding presents the main activities of the students that included the definition of the geometry of the detector, the realisation of the structure prepared by Scanny3D, the optimisation of the coupling between the water and the sensors, the experiences with 18F (prepared by Acom SRL) and 226Rd radioactive sources, and the results of the tests performed at the Beam Test Facility in INFN-Frascati in 2016.The team proposed to expose the detector to a test beam at CERN in 2016 and in 2017 within the Beamline for School initiative.

Application of SiPM arrays for the readout of a scintillator based time-of-flight detector / Korzenev, Alexander (Geneva U.) ; Betancourt, C (Zurich U.) ; Blondel, A (Geneva U.) ; Brundler, R (Zurich U.) ; Dätwyler, A (Zurich U.) ; Favre, Y (Geneva U.) ; Gascon, D (ICC, Barcelona U.) ; Gomez, S (ICC, Barcelona U.) ; Mermod, P (Geneva U.) ; Noah, E (Geneva U.) et al.
A feasibility study of replacing a conventional phototube with an array of SiPMs is presented. High gain, low voltage operation and insensitivity to the magnetic field make SiPMs practically useful for the light collection in a physics experiment. [...]
