Local Interaction Region Coupling Correction for the LHC
/ Soubelet, Felix
In order to further expand our knowledge of the structure of matter and the workings of our universe, scientists are constantly seeking to collide particles at ever-increasing energies and with higher luminosity. So is the task of the Large Hadron Collider (LHC) at CERN, the highest energy particle accelerator and collider to date, and the goal of its future upgrade into the High-Luminosity Large Hadron Collider (HL-LHC). [...]

MACHINA, the Movable Accelerator for Cultural Heritage In-situ Non-destructive Analysis: project overview
/ Taccetti, F (INFN, Florence) ; Castelli, L (INFN, Florence) ; Chiari, M (INFN, Florence) ; Czelusniak, C (INFN, Florence) ; Falciano, S (INFN, Rome ; GSSI, Aquila) ; Fedi, M (INFN, Florence) ; Giambi, F (INFN, Florence ; Florence U.) ; Mandò, P A (INFN, Florence ; Florence U.) ; Manetti, M (INFN, Florence) ; Massi, M (INFN, Florence) et al.
Over the years, transportable instrumentation for cultural heritage (CH) in situ measurements has noticeably widespread, due to logistic, economical and safety reasons. Ion beam analysis, a powerful set of analytical techniques, of great importance for CH, is instead carried out by using fixed instrumentation. [...]

FOCUS: fast Monte Carlo approach to coherence of undulator sources
/ Siano, M (Milan U. ; INFN, Milan) ; Geloni, G (European XFEL, Hamburg) ; Paroli, B (Milan U. ; INFN, Milan) ; Butti, D (CERN) ; Lefèvre, T (CERN) ; Mazzoni, S (CERN) ; Trad, G (CERN) ; Iriso, U (CELLS - ALBA, LLS) ; Nosych, A A (CELLS - ALBA, LLS) ; Torino, L (CELLS - ALBA, LLS) et al.
FOCUS (Fast Monte CarlO approach to Coherence of Undulator Sources) is a new GPU-based simulation code to compute the transverse coherence of undulator radiation from ultra-relativistic electrons. The core structure of the code, which is written in the language C++ accelerated with CUDA, combines an analytical description of the emitted electric fields and massively parallel computations on GPUs.

Application of Proton Irradiation in the Study of Accelerated Radiation Ageing in a GaAs Semiconductor
/ Neuhold, Igor (Bratislava, Slovak Tech. U. ; CERN) ; Noga, Pavol (Bratislava, Slovak Tech. U.) ; Sojak, Stanislav (Bratislava, Slovak Tech. U.) ; Petriska, Martin (Bratislava, Slovak Tech. U.) ; Degmova, Jarmila (Bratislava, Slovak Tech. U.) ; Slugen, Vladimir (Bratislava, Slovak Tech. U.) ; Krsjak, Vladimir (Bratislava, Slovak Tech. U.)
Proton irradiation experiments have been used as a surrogate for studying radiation effects
in numerous materials for decades. The abundance and accessibility of proton accelerators make
this approach convenient for conducting accelerated radiation ageing studies. [...]

Growth of Nb films on Cu for superconducting radio frequency cavities by direct current and high power impulse magnetron sputtering: A molecular dynamics and experimental study
/ Ghaemi, M (Helsinki Inst. of Phys.) ; Lopez-Cazalilla, A (Helsinki Inst. of Phys.) ; Sarakinos, K (Helsinki U. ; Royal Inst. Tech., Stockholm) ; Rosaz, G J (CERN) ; Carlos, C P A (CERN) ; Leith, S (CERN) ; Calatroni, S (CERN) ; Himmerlich, M (CERN) ; Djurabekova, F (Helsinki Inst. of Phys.)
The use of superconducting radio frequency (rf) cavities in particle accelerators necessitates that copper (Cu) surfaces are coated by thin niobium (Nb) films, predominantly synthesized by magnetron sputtering. A key feature of the rf cavities is that they exhibit a complex three-dimensional geometry, such that during Nb film growth vapor is not deposited on a flat substrate [...]
