Requirements and Results for Quadrupole Mode Measurements / Oeftiger, Adrian (CERN)
Direct space charge may be quantified, and hence the beam brightness observed, by measuring the quadrupolar beam modes in the CERN Proton Synchrotron (PS). The spectrum of the transverse beam size oscillations (i.e. [...]

Linac4 Commissioning Status and Challenges to Nominal Operation / Bellodi, Giulia (CERN) /Linac4
Linac4 will be connected to the Proton Synchrotron Booster (PSB) during the next long LHC shutdown in 2019 and it will operationally replace Linac2 as provider of protons to the CERN complex as of 2021. Commissioning to the final beam energy of 160 MeV was achieved by the end of 2016. [...]

High Intensity Effects of Fixed Target Beams in the CERN Injector Complex / Koukovini-Platia, Eirini (CERN) ; Bartosik, Hannes (CERN) ; Migliorati, Mauro (CERN ; INFN, Rome ; Rome U.) ; Rumolo, Giovanni (CERN)
The current fixed target (FT) experiments at CERN are a complementary approach to the Large Hadron Collider (LHC) and play a crucial role in the investigation of fundamental questions in particle physics. Within the scope of the LHC Injectors Upgrade (LIU), aiming to improve the LHC beam production, the injector complex will be significantly upgraded during the second Long Shutdown (LS2). [...]

Approaching the High-Intensity Frontier Using the Multi-Turn Extraction at the CERN Proton Synchrotron / Huschauer, Alexander (CERN) ; Bartosik, Hannes (CERN) ; Cettour-Cave, Stephane (CERN) ; Coly, Marcel (CERN) ; Cotte, Denis (CERN) ; Damerau, Heiko (CERN) ; Di Giovanni, Gian Piero (CERN) ; Gilardoni, Simone (CERN) ; Giovannozzi, Massimo (CERN) ; Kain, Verena (CERN) et al.
Complementary to the physics research at the LHC, sev- eral fixed target facilities receive beams from the LHC in- jector complex. To serve the fixed target physics program at the Super Proton Synchrotron, high-intensity proton beams from the Proton Synchrotron are extracted using the Multi- Turn Extraction technique based on trapping parts of the beam in stable resonance islands.

Simulation and Measurement Campaigns for Characterization and Performance Improvement of the CERN Heavy Ion Linac3 / Bellodi, Giulia (CERN) ; Benedetti, Stefano (CERN) ; Küchler, Detlef (CERN) ; Toivanen, Ville (GANIL) ; Wenander, Fredrik (CERN)
In the framework of the LHC Injector Upgrade programme (LIU), several activities have been carried out to improve the GTS-LHC ion source and Linac3 performance (Linac3 providing the charged heavy ion beams for CERN exper-iments). A restudy of the beam dynamics and transport through the linac was initiated, through a campaign of systematic machine measurements and parallel beam simulations, generalising techniques developed for beam characterization during Linac4 commissioning.

Beam test of a small MICROMEGAS DHCAL prototype / Adloff, C (Annecy, LAPP) ; Blaha, J (Annecy, LAPP) ; Chefdeville, M (Annecy, LAPP) ; Dalmaz, A (Annecy, LAPP) ; Drancourt, C (Annecy, LAPP) ; Espargiliere, A (Annecy, LAPP) ; Gaglione, R (Annecy, LAPP) ; Karyotakis, Y (Annecy, LAPP) ; Prast, J (Annecy, LAPP) ; Vouters, G (Annecy, LAPP)
A sampling hadronic calorimeter with gaps instrumented with thin MICROMEGAS chambers of small pad size and single bit readout is a candidate for an experiment at a future linear collider. Several MICROMEGAS chambers with 1 cm(2) anode pads were fa bricated using the Bulk technology. [...]
