Nuclear Charge Radii of the Nickel Isotopes $^{58-68,70}$Ni
/ Malbrunot-Ettenauer, S. (CERN) ; Kaufmann, S. (Darmstadt, Tech. U.) ; Bacca, S. (Mainz U., Inst. Kernchem. ; Helmholtz Inst., Mainz) ; Barbieri, C. (Surrey U. ; Milan U. ; INFN, Milan) ; Billowes, J. (Manchester U.) ; Bissell, M.L. (Manchester U.) ; Blaum, K. (Heidelberg, Max Planck Inst.) ; Cheal, B. (Liverpool U.) ; Duguet, T. (IRFU, Saclay) ; Ruiz, R.F. Garcia (CERN ; Manchester U.) et al.
Collinear laser spectroscopy is performed on the nickel isotopes $^{58-68,70}$Ni, using a time-resolved photon counting system. From the measured isotope shifts, nuclear charge radii $R_c$ are extracted and compared to theoretical results. [...]

Mass measurements of $^{99-101}$In challenge ab initio nuclear theory of the nuclide $^{100}$Sn
/ Mougeot, M. (Heidelberg, Max Planck Inst. ; CERN) ; Atanasov, D. (CERN) ; Karthein, J. (Heidelberg, Max Planck Inst. ; CERN) ; Wolf, R.N. (Sydney U.) ; Ascher, P. (CENBG, Gradignan) ; Blaum, K. (Heidelberg, Max Planck Inst.) ; Chrysalidis, K. (CERN) ; Hagen, G. (Tennessee U. ; Oak Ridge) ; Holt, J.D. (TRIUMF ; McGill U.) ; Huang, W.J. (Heidelberg, Max Planck Inst.) et al.
$^{100}$Sn is of singular interest for nuclear structure. Its closed-shell proton and neutron configuration exhibit exceptional binding and $^{100}$Sn is the heaviest nucleus comprising protons and neutrons in equal number, a feature that enhances the contribution of the short-range, proton-neutron pairing interaction and strongly influences its decay via the weak interaction.

/ Bacca, S ; Barbi, M ; Bravar, A ; Berns, L ; Bhadra, S ; Bordoni, S ; Bubak, A ; de Perio, P ; Fedotov, S ; Fiorentini, A et al.
This expression of interest describes a proposal to precisely measure forward hadron scattering cross-sections, namely measurement of total, coherent elastic, and quasi-elastic scatterings, on nuclear targets in the momentum range of1−10GeV/c. [...]

Powering Tests and Magnet Training
/ Mentink, M (CERN) ; Apollonio, A (CERN) ; Bednarek, M (CERN) ; Calcoen, D (CERN) ; Charifoulline, Z (CERN) ; Hagen, P (CERN) ; Naour, S Le (CERN) ; Pojer, M (CERN) ; Scheuerlein, C (CERN) ; Steckert, J (CERN) et al.
In this paper the powering tests and magnet training during the hardware
commissioning campaigns of Run 2 are discussed, and the implications of running
at 7 TeV from a magnet training and reliability perspective are given. During
Run 2, the efficiency of powering tests has steadily increased due to enhanced
control software, more automatic analysis, and more experienced CERN personnel.
The MP3 Intervention Matrix, used for documenting requalification procedures
after interventions, is presented. [...]

Charge radii of exotic potassium isotopes challenge nuclear theory and the magic character of $N = 32$
/ Koszorús, Á. (Leuven U.) ; Yang, X.F. (Peking U., SKLNPT) ; Jiang, W.G. (U. Tennessee, Knoxville ; Oak Ridge ; Chalmers U. Tech.) ; Novario, S.J. (U. Tennessee, Knoxville ; Oak Ridge) ; Bai, S.W.

Nuclear charge radii are sensitive probes of different aspects of the nucleon-nucleon interaction and the bulk properties of nuclear matter; thus, they provide a stringent test and challenge for nuclear theory. The calcium region has been of particular interest, as experimental evidence has suggested a new magic number at $N = 32$ [1-3], while the unexpectedly large increases in the charge radii [4,5] open new questions about the evolution of nuclear size in neutron-rich systems.

Training of the Main Dipoles Magnets in the Large Hadron Collider Toward 7 TeV Operation

During 2016, one-quarter of the LHC main dipoles have has been powered above the 7.7 T operational field, to reach a field of 8.1 T. These tests were done to confirm the extrapolation of the training behavior based on a Gaussian tail of the quench distribution. [...]

Sloan Digital Sky Survey IV: Mapping the Milky Way, Nearby Galaxies and the Distant Universe
/ Blanton, Michael R. (Stanford U., Phys. Dept.) ; Bershady, Matthew A. (Wisconsin U., Madison, Astron.) ; Abolfathi, Bela ; Albareti, Franco D. (Madrid, Autonoma U. ; Madrid, IFT) ; Allende Prieto, Carlos ; Almeida, Andres ; Alonso-García, Javier ; Anders, Friedrich (Potsdam, Astrophys. Inst.) ; Anderson, Scott F. (LLNL, Livermore) ; Andrews, Brett et al.
We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is observing hundreds of thousands of Milky Way stars at high resolution and high signal-to-noise ratio in the near-infrared.
