Ontological Opportunism : Reanimating the Inanimate in Physics and Science Communication at CERN / Dippel, Anne (Jena U.)
Understanding inanimate ‘nature-as-such’ is traditionally considered the object of physics in Europe. The discipline acts as exemplary discursive practice of scientific knowledge production. [...]

Das Big Data Game : Zur spielerischen Konstitution kollaborativer Wissensproduktion in der Hochenergiephysik am CERN / Dippel, Anne (Friedrich-Schiller U., Jena)
Der vorliegende Artikel widmet sich der Frage, wie Spiele und spielen zur Big-Data-basierten Wissensproduktion in der Hochenergiephysik beitragen. Als Beispiel dienen Detektorkollaborationen am Large Hadron Collider (LHC) der Europäischen Organisation für Kernforschung (CERN), in denen die Autorin seit 2014 kulturanthropologische Feldforschung unternommen hat.

MBGEM: a stack of borated GEM detector for high efficiency thermal neutron detection / Muraro, A (ISTP, Milan ; Milan Bicocca U. ; INFN, Milan Bicocca) ; Claps, G (Frascati ; ENEA, FEL, Frascati) ; Croci, G (ISTP, Milan ; Milan Bicocca U. ; INFN, Milan Bicocca) ; Lai, C C (Linkoping U. ; ESS, Lund) ; De Oliveira, R (CERN) ; Altieri, S (Pavia U.) ; Cancelli, S (ISTP, Milan ; Milan Bicocca U.) ; Gorini, G (ISTP, Milan ; Milan Bicocca U. ; INFN, Milan Bicocca) ; Hall-Wilton, R (Milan Bicocca U. ; ESS, Lund) ; Höglund, C (ESS, Lund ; Unlisted, SE) et al.
A new position-sensitive thermal neutron detector based on boron-coated converters has been developed as an alternative to today’s standard $^3\mathrm{He}$-based technology for application to thermal neutron scattering. The key elements of the development are the boron-coated GEM foils (Sauli in Nucl Instrum Methods Phys Res Sect A Accel Spectrom Detect Assoc Equip 386:531, 1997) that are used as a multi-layer neutron converter via the $^{10}\mathrm{B}(n,\alpha )^7\mathrm{Li}$ reaction together with an efficient collection of the produced secondary electrons.

Electrically Small Antenna for BeiDou Chinese Navigation Satellite System / Yashchyshyn, Yevhen (Warsaw U. of Tech.) ; Vynnyk, Dmytro (Lvov Nat. U.) ; Haiduchok, Volodymyr (Unlisted, UK) ; Solskii, Ivan (Unlisted, UK) ; Wu, Changying (Xian, NWPU) ; Bogdan, Grzegorz (Warsaw U. of Tech.)
A concept of electrically small antenna for BeiDou BD2 B3 Chinese navigation satellite system was developed and studied. Three main miniaturized techniques: antenna loading by using high permittivity materials, making some part of antennas virtual by using ground planes and short circuits, and optimizing geometry have been employed in the design.

Laser-assisted decay spectroscopy and mass spectrometry of $^{178}\mathrm{Au}$ / Cubiss, J G ; Andreyev, A N ; Barzakh, A E ; Manea, V ; Al Monthery, M ; Althubiti, N A ; Andel, B ; Antalic, S ; Atanasov, D ; Blaum, K et al.
A comprehensive study of the isotope 178 Au has been made at the CERN-ISOLDE facility, using resonance laser ionization. Two long-lived states in 178 Au were identified—a low-spin ground state and a high-spin isomer—each of which were produced as pure beams. [...]

Study of SEU Sensitivity of SRAM-Based Radiation Monitors in 65-nm CMOS / Wang, Jialei (Leuven U.) ; Prinzie, Jeffrey (Leuven U.) ; Coronetti, Andrea (CERN ; Jyvaskyla U.) ; Thys, S (Leuven U.) ; Alia, Rubén García (CERN) ; Leroux, Paul (Leuven U.)
This article presents a static random access memory (SRAM)-based flexible radiation monitor. The monitor was fabricated in a 65-nm CMOS technology and it is designed as an application-specific integrated circuit, which comprises 768k bits SRAM cell matrix with individual power supply and a digital control core with a serial peripheral interface (SPI).

Experimental Study of Frequency Modulation in Single-Frequency Lasers / Skliarov, Philipp V ; Muravyov, Konstantin V ; Kostromitin, Aleksei O
The paper presents an experimental investigation of frequency modulation of different types of single-frequency lasers. Dependences of frequency modulation coefficients on modulating frequency were obtained experimentally and parasitic intensity modulation was estimated. [...]

Isotope Shift of Nuclear Magnetic Resonances in 129Xe and 131Xe Caused by Spin-Exchange Pumping by Alkali Metal Atoms / Petrov, Vladimir I ; Pazgalev, Anatoly S (Ioffe Phys. Tech. Inst.) ; Vershovskii, Anton K (Ioffe Phys. Tech. Inst.)
The effect of isotope shifts of nuclear magnetic resonance (NMR) frequency in xenon isotopes 129Xe and 131Xe polarized by optically-oriented alkali metal atoms is not only of fundamental interest, but also of practical significance, since it is the main factor limiting the accuracy of a whole class of prospective navigation and metrological devices. Our study of the parametric dependences of the isotope shift has shown that this effect is largely due to incomplete averaging of an inhomogeneous local magnetic field by two xenon isotopes, and therefore, its value can be influenced by applying an external magnetic field gradient.

Calculation of a magnetic force acting on small superconducting celestial bodies / Tomkow, Lukasz
Recent discoveries of superconducting phases in the samples of meteorites suggest the possibility of a natural occurrence of superconducting state in space. Superconductors are known to exhibit interesting behaviours when subjected to external magnetic fields, such as levitation. [...]

Electron-Induced Upsets and Stuck Bits in SDRAMs in the Jovian Environment / Söderström, Daniel ; Luza, Lucas Matana ; Kettunen, Heikki ; Javanainen, Arto ; Farabolini, Wilfrid ; Gilardi, Antonio ; Coronetti, Andrea ; Poivey, Christian ; Dilillo, Luigi
This study investigates the response of synchronous dynamic random access memories to energetic electrons and especially the possibility of electrons to cause stuck bits in these memories. Three different memories with different node sizes (63, 72, and 110 nm) were tested. [...]
