Dipole and quadrupole moments of $^{73-78}$Cu as a test of the robustness of the $Z=28$ shell closure near $^{78}$Ni / de Groote, R.P. ; Billowes, J. ; Binnersley, C.L. ; Bissell, M.L. ; Cocolios, T.E. ; Day Goodacre, T. (CERN) ; Farooq-Smith, G.J. ; Fedorov, D.V. ; Flanagan, K.T. ; Franchoo, S. et al.
Nuclear spins and precise values of the magnetic dipole and electric quadrupole moments of the ground-states of neutron-rich $^{76-78}$Cu isotopes were measured using the Collinear Resonance Ionization Spectroscopy (CRIS) experiment at ISOLDE, CERN. The nuclear moments of the less exotic $^{73,75}$Cu isotopes were re-measured with similar precision, yielding values that are consistent with earlier measurements. [...]

Status of the HIE-ISOLDE project at CERN / Fraser, M.A. ; Kadi, Y. ; Bernardes, A.P. ; Blumenfeld, Y. ; Bravin, E. ; Calatroni, S. ; Catherall, R. ; Goddard, B. ; Parchet, D. ; Siesling, E. et al.
The HIE-ISOLDE project represents a major upgrade of the ISOLDE nuclear facility with a mandate to significantly improve the quality and increase the intensity and energy of radioactive nuclear beams produced at CERN. The project will expand the experimental nuclear physics programme at ISOLDE by focusing on an upgrade of the existing Radioactive ion beam EXperiment (REX) linac with a 40 MV superconducting linac comprising thirty-two niobium-on-copper sputter-coated quarter-wave resonators housed in six cryomodules.

Discharge and stability studies for the new readout chambers of the upgraded ALICE TPC / Deisting, Alexander (Darmstadt, GSI) ; Garabatos, Chilo (Darmstadt, GSI) /ALICE Collaboration
The ALICE (A Large Ion Collider Experiment) Time Projection Chamber (TPC) at CERN LHC is presently equipped with Multi Wire Proportional Chambers (MWPCs). A gating grid prevents ions produced during the gas amplification from moving into the drift volume. [...]

Heavy flavour production in proton–lead and lead–lead collisions with LHCb / Winn, Michael (Orsay, LAL)
The LHCb experiment offers the unique opportunity to study heavy-ion interactions in the forward region (2 <eta< 5), in a kinematic domain complementary to the other 3 large experiments at the LHC. The detector has excellent capabilities for reconstructing quarkonia and open charm states, including baryons, down to zero $p_T$. [...]

Simulation study of signal formation in position sensitive planar p-on-n silicon detectors after short range charge injection / Peltola, Timo (Texas Tech. ; Helsinki Inst. of Phys.) ; Eremin, Vladimir (Boskovic Inst., Zagreb) ; Verbitskaya, Elena (Boskovic Inst., Zagreb) ; Härkönen, Jaakko (Helsinki Inst. of Phys. ; Helsinki U.)
Segmented silicon detectors (micropixel and microstrip) are the main type of detectors used in the inner trackers of Large Hadron Collider (LHC) experiments at CERN. Due to the high luminosity and eventual high fluence, detectors with fast response to fit the short shaping time of 20 ns and sufficient radiation hardness are required. [...]

A radiation-hard dual-channel 12-bit 40 MS/s ADC prototype for the ATLAS liquid argon calorimeter readout electronics upgrade at the CERN LHC / Kuppambatti, Jayanth (Columbia U.) ; Ban, Jaroslav (Nevis Labs, Columbia U.) ; Andeen, Timothy (Nevis Labs, Columbia U.) ; Brown, Rex (Nevis Labs, Columbia U.) ; Carbone, Ryne (Nevis Labs, Columbia U.) ; Kinget, Peter (Columbia U.) ; Brooilmans, Gustaaf (Nevis Labs, Columbia U.) ; Sippach, William (Nevis Labs, Columbia U.)
The readout electronics upgrade for the ATLAS Liquid Argon Calorimeters at the CERN Large Hadron Collider requires a radiation-hard ADC. The design of a radiation-hard dual-channel 12-bit 40 MS/s pipeline ADC for this use is presented. [...]

Precision Luminosity of LHC Proton-Proton Collisions at 13 TeV Using Hit-Counting with TPX Pixel Devices / Sopczak, André (IEAP CTU, Prague) ; Ali, Babar (IEAP CTU, Prague) ; Asawatavonvanich, Thanawat (IEAP CTU, Prague) ; Begera, Jakub (IEAP CTU, Prague) ; Bergmann, Benedikt (IEAP CTU, Prague) ; Billoud, Thomas (Montreal U.) ; Burian, Petr (IEAP CTU, Prague) ; Caicedo, Ivan (IEAP CTU, Prague) ; Caforio, Davide (IEAP CTU, Prague) ; Heijne, Erik (IEAP CTU, Prague) et al.
A network of Timepix (TPX) devices installed in the ATLAS cavern measures the LHC luminosity as a function of time as a stand-alone system. The data were recorded from 13 TeV proton-proton collisions in 2015. [...]

Neutron irradiation test of depleted CMOS pixel detector prototypes / Mandić, Igor (Stefan Inst., Ljubljana) ; Cindro, Vladimir (Stefan Inst., Ljubljana) ; Gorišek, Andrej (Stefan Inst., Ljubljana) ; Hiti, Bojan (Stefan Inst., Ljubljana) ; Kramberger, Gregor (Stefan Inst., Ljubljana) ; Mikuž, Marko (Stefan Inst., Ljubljana ; Ljubljana U.) ; Zavrtanik, Marko (Stefan Inst., Ljubljana) ; Hemperek, Tomasz (Bonn U.) ; Daas, Michael (Bonn U.) ; Hügging, Fabian (Bonn U.) et al.
Charge collection properties of depleted CMOS pixel detector prototypes produced on p-type substrate of 2 k$\Omega$cm initial resistivity (by LFoundry 150 nm process) were studied using Edge-TCT method before and after neutron irradiation. The test structures were produced for investigation of CMOS technology in tracking detectors for experiments at HL-LHC upgrade. [...]

Impact of LHC and SPS Injection Kicker Rise Times on Lhc Filling Schemes and Luminosity Reach / Bartmann, Wolfgang (CERN) ; Barnes, Michael (CERN) ; Boyd, Jamie (CERN) ; Carlier, Etienne (CERN) ; Chmielinska, Agnieszka (CERN) ; Goddard, Brennan (CERN) ; Kotzian, Gerd (CERN) ; Schwick, Christoph (CERN) ; Stoel, Linda (CERN) ; Valuch, Daniel (CERN) et al.
The 2016 LHC proton filling schemes generally used a spacing between injections of batches of bunches into SPS and LHC corresponding to the design report specification for the SPS and LHC injection kicker rise times, respectively. A reduction of the batch spacing can be directly used to increase luminosity without detrimental effects on beam stability, and with no increase in the number of events per crossing seen by the experiments.
