Effects of the extraction voltage applied by the puller-electrode on the H$^−$ extraction in the Linac4 negative ion source
/ Abe, S (Keio U.) ; Nishioka, S (Keio U.) ; Mattei, S (CERN) ; Hatayama, A (Keio U.) ; Lettry, J (CERN)
In order to understand the H$^−$ extraction mechanism and investigate the effect of the extraction voltage applied by the puller-electrode on the H$^−$ extraction in the Linac4 negative ion source, we are developing a 2D3V-PIC (two dimensions in the real space and three dimensions in the velocity space, Particle in Cell) model with volume produced H$^−$ ions. It is shown that how to take the magnetic filter field direction is important for the 2D modeling to take into account the important 3D effect of electron $E \times B$ drift. [...]

/n_TOF
The experimental area 2 (EAR-2) at CERNs neutron time-of-flight facility (n_TOF), which is operational since 2014, is designed and built as a short-distance complement to the experimental area 1 (EAR-1). The Parallel Plate Avalanche Counter (PPAC) monitor experiment was performed to characterize the beam profile and the shape of the neutron flux at EAR-2. [...]

Measurement and Analysis of the Dynamic Effects in an HTS Dipole Magnet
/ Petrone, Carlo (CERN) ; van Nugteren, Jeroen (CERN) ; Bajas, Hugues (CERN) ; Bottura, Luca (CERN) ; Kirby, Glyn (CERN) ; Rossi, Lucio (CERN) ; Russenschuck, Stephan (CERN)
The EuCARD-2 project, co-funded by the European Commission, supports the design, production and standalone cold testing of a high-temperature, superconducting demonstrator insert-magnet. The so-called Feather-M2 dipole magnet was built at CERN, using Roebel cable consisting of REBCO coated conductor tapes. [...]

First experience with carbon stripping foils for the 160 MeV H− injection into the CERN PSB
/ Weterings, Wim (CERN) ; Bracco, Chiara (CERN) ; Jorat, Louise (CERN) ; Noulibos, Remy (CERN) ; van Trappen, Pieter (CERN)
160 MeV H− beam will be delivered from the new CERN linear accelerator (Linac4) to the Proton Synchrotron Booster (PSB), using a H− charge-exchange injection system. A 200 µg/cm2 carbon stripping foil will convert H− into protons by stripping off the electrons. [...]

Evaluation of strip-line pick-up system for the SPS wideband transverse feedback system
/ Kotzian, G (CERN) ; Hofle, W (CERN) ; Steinhagen, R J (CERN) ; Valuch, D (CERN) ; Wehrle, U (CERN)
The proposed SPS Wideband Transverse Feedback sys- tem requires a wide-band pick-up system to be able to de- tect intra-bunch motion within the SPS proton bunches, captured and accelerated in a 200 MHz bucket. We present the electro-magnetic design of transverse beam position pick-up options optimised for installation in the SPS and evaluate their performance reach with respect to direct time domain sampling of the intra-bunch motion.

The n_TOF facility: Neutron beams for challenging future measurements at CERN
/ Chiaveri, E (CERN ; U. Manchester (main) ; Seville U.) ; Aberle, O (CERN) ; Andrzejewski, J ; Audouin, L ; Bacak, M (CERN ; TU Vienna ; IRFU, Saclay) ; Balibrea, J ; Barbagallo, M ; Bečvář, F ; Berthoumieux, E ; Billowes, J et al.
The CERN n_TOF neutron beam facility is characterized by a very high instantaneous neutron flux, excellent TOF resolution at the 185 m long flight path (EAR-1), low intrinsic background and coverage of a wide range of neutron energies, from thermal to a few GeV. These characteristics provide a unique possibility to perform high-accuracy measurements of neutron-induced reaction cross-sections and angular distributions of interest for fundamental and applied Nuclear Physics.
