Effect of Applied Compressive Stress and Impregnation Material on Internal Strain and Stress State in Nb$_3$Sn Rutherford Cable Stacks
/ Wolf, Felix (CERN) ; Scheuerlein, Christian (CERN) ; Lorentzon, Marcus (CERN) ; Katzer, Balduin (CERN) ; Hofmann, Michael (Forschungsreaktor Munich) ; Gan, Weimin ; Lackner, Friedrich (CERN) ; Schoerling, Daniel (CERN) ; Tommasini, Davide (CERN) ; Savary, Frederic (CERN) et al.
The Nb3Sn superconductor in accelerator magnets must resist high mechanical stresses. In order to better understand the effect of the coil impregnation system on the stresses exerted on the strain-sensitive Nb3Sn superconductor, we have measured the elastic strain evolution in the conductor constituents under externally applied loads.

Upgrade of the monitoring system of LHCb ECAL
/ Guz, Yu (Serpukhov, IHEP) ; Konoplyannikov, A (Moscow, ITEP) ; Perret, P (Clermont-Ferrand U.) ; Shatalov, P (Moscow, ITEP)
/LHCb
In order to improve the stability of the LHCb ECAL monitoring system, the light guides transporting LED light to PMTs have been replaced by radiation hard quartz fibers. The behavior of transparency of the selected fibers under moderate radiation doses, up to few kGy, was studied in detail. [...]

A number of innovative experiments dedicated to neutrino and rare-event physics use liquefied noble-gases both as a target and as a detector. These media have the remarkable property to efficiently produce scintillation photons after the passage of ionizing particles. [...]

Timing properties of Hamamatsu R5912-MOD photomultiplier tube for the ICARUS T600 light detection system
/ Babicz, Marta (CERN ; AGH-UST, Cracow) ; Bellini, Vincenzo (INFN, Catania ; Catania U.) ; Bonesini, Maurizio (INFN, Milan Bicocca) ; Cervi, Tommaso (INFN, Pavia ; Pavia U.) ; Falcone, Andrea (Texas U., Arlington) ; Menegolli, Alessandro (INFN, Pavia ; Pavia U.) ; Montanari, Claudio (INFN, Pavia) ; Raselli, Gian Luca (INFN, Pavia) ; Rossella, Massimo (INFN, Pavia) ; Spanu, Maura (INFN, Pavia ; Pavia U.) et al.
The ICARUS T600 liquid argon time projection chamber (LAr-TPC) will operate at shallow depth as far detector for the Short Baseline Neutrino (SBN) program at FNAL. A new scintillation light detection system, with a time resolution of the order of the nanosecond, is required to distinguish the actual beam related events from the huge cosmic background. [...]

Neutron irradiation effect on SiPMs up to $\Phi_{neq}$ = 5 $\times$ 10$^{14}$ cm$^{-2}$
/ Centis Vignali, M. (CERN) ; Garutti, E. (Hamburg U.) ; Klanner, R. (Hamburg U.) ; Lomidze, D. (Hamburg U.) ; Schwandt, J. (Hamburg U.)
Silicon Photo-Multipliers (SiPM) are becoming the photo-detector of choice for increasingly more particle detection applications, from fundamental physics to medical and societal applications. One major consideration for their use at high-luminosity colliders is the radiation damage induced by hadrons, which leads to a dramatic increase of the dark count rate. [...]

Development of monolithic sensors for high energy physics in commercial CMOS technologies
/ Snoeys, W (CERN)
Hybrid pixel detectors with readout and sensor in different silicon chips are in overwhelming majority in today’s high energy physics experiments, but monolithic active pixel sensors (MAPS) have received significant attention because they offer easier detector assembly, lower cost, and other advantages like lower material and higher granularity. MAPS now move towards commercial CMOS technologies, which offer significant radiation tolerance and substrates compatible with particle detection and combine circuit performance and density with volume production capability at reasonable cost.

Measurement of the $^{244}Cm$ and $^{246}Cm$ neutron-induced capture cross sections at the n_TOF facility
/ Alcayne, V (Madrid, CIEMAT) ; Kimura, A (JAERI, Tokai) ; Mendoza, E (Madrid, CIEMAT) ; Cano-Ott, D (Madrid, CIEMAT) ; Martínez, T (Madrid, CIEMAT) ; Aberle, O (CERN) ; Andrzejewski, J (Lodz U.) ; Audouin, L (Orsay, IPN) ; Bécares, V (Madrid, CIEMAT) ; Bacak, M (CERN ; IRFU, Saclay ; Vienna, Tech. U.) et al.
The neutron capture reactions of the $^{244}$Cm and $^{246}$Cm isotopes open the path for the formation of heavier Cm isotopes and heavier elements such as Bk and Cf in a nuclear reactor. In addition, both isotopes belong to the minor actinides with a large contribution to the decay heat and to the neutron emission in irradiated fuels. [...]
