 The stripping foil test stand in the Linac4 transfer line / Weterings, W (CERN) ; Bracco, C (CERN) ; Noulibos, R (CERN) ; Sillanoli, Y (CERN) ; van Trappen, P (CERN) The 160 MeV H− beam from the Linac4 (L4) linear accelerator at CERN will be injected into the proton synchrotron booster (PSB) with a new H− charge-exchange injection system. It will include a stripping foil, to convert H− into protons by stripping off the electrons. [...] 2015 - Published in : J. Radioanal. Nucl. Chem. xx (2015) xx Fulltext: PDF;

Status of the FCC-ee Interaction Region Design / Martin, R (CERN and Humboldt University); Tomas, R (CERN); Medina, L (Universidad de Guanajuato, Mexico)
The FCC-ee project is a high-luminosity circular electron-positron collider envisioned to operate at center-of-mass energies from90 to 350GeV, allowing high-precision measurements of the properties of the Z, W and Higgs boson as well as the top quark. It is considered to be a predecessor of a new 100 TeV proton-proton collider hosted in the same 80 to 100 km tunnel in the Geneva area. [...]

 Drift Tube Linac Conditioning of Tank1 / Shafqat, N (Pakistan Atomic Energy Commission) ; Ramberger, S (-) ; Toor, W A (Pakistan Atomic Energy Commission) Tank1 of the Drift Tube Linac (DTL) of the Linac4 has been conditioned at the Linac4 tunnel. The tank was tuned for resonance at 352.2 MHz, and stable operation has been achieved with 725 µs long RF pulses at a repetition rate of 1 Hz [...] sLHC-Project-Note-0043; CERN-sLHC-Project-Note-0043.- Geneva : CERN, 2014 - 6 p.

 The Electrical Resistance of Rutherford-Type Superconducting Cable Splices / Heck, C (CERN, Switzerland) ; Scheuerlein, Chr (CERN, Switzerland) ; Fleiter, J (CERN, Switzerland) ; Bottura, L (CERN, Switzerland) The electrical resistance of Large Hadron Collider main busbar cable lap splices produced by soft soldering has been measured with two independent methods as a function of intercable contact area and for splices made of cables with various defects. For defect-free lap splices, the resistance increases from 0.3 to 10 nΩ (at 4.3 K in self-field) when reducing the cable overlap length from 120 to 3 mm, as expected assuming that the resistance is inversely proportional to the intercable contact area.

 Multipactor Mitigation in Coaxial Lines by Means of Permanent Magnets / Gonzalez-Iglesias, D ; Perez, A M ; Anza, S ; Vague, J ; Gimeno, B ; Boria, V E ; Raboso, D ; Vicente, C ; Gil, J ; Caspers, F et al. The main aim of this paper is the analysis of the feasibility of employing permanent magnets for the multipactor mitigation in a coaxial waveguide. First, the study of a coaxial line immersed in a uniform axial magnetic field shows that multipactor can be suppressed at any RF frequency if the external magnetic field is strong enough.

 Efficient Parametric Identification Method for High Voltage Pulse Transformers / Aguglia, D (CERN, Switzerland) ; Candolfi, S (LEEPCI Lab., Quebec, Canada) ; Viarouge, P (LEEPCI Lab., Quebec, Canada) ; Cros, J (LEEPCI Lab., Quebec, Canada) This paper presents a new identification method for a pulse transformer equivalent circuit. It is based on an analytical approximation of the frequency-domain impedance data derived from a no-load test with open-circuited secondary winding and only requires measurements of primary current and voltage without phase data.

 Design of a system of high voltage pulsed power converters for CERN’s Linac4 H$^{−}$ ion source / Aguglia, D (CERN, Switzerland) This paper presents the complete design and experimental validations of the full scale prototype of a system of three new high voltage pulsed power converters for the CERN Linac4 H$^{−}$ source. The system requires three pulsed voltages (50kV, 40kV and 25kV to ground) at 2Hz repetition rate, for a 700µs of usable flat-top. [...] CERN-ACC-2014-0345.- Geneva : CERN, 2014 - 7 p.
