Vacuum ultraviolet optical properties of GaSb determined by synchrotron rotating analyzer ellipsometry: applications in nanopillars and plasmonics / Hale, Nathan (Norwegian U. Sci. Tech.) ; Bjelland, Victoria M (CERN ; Norwegian U. Sci. Tech.) ; Cobet, Christoph (Linz U.) ; Esser, Norbert (Berlin, Tech. U.) ; Kildemo, Morten (Norwegian U. Sci. Tech.)
The vacuum ultraviolet (VUV) optical properties in the range 4 eV to 15 eV of GaSb have been determined by rotating analyzer ellipsometry (RAE) using synchrotron light. The localized surface plasmon resonances (LSPRs) and surface plasmon polaritons (SPPs) are studied as a means to understand the plasmonic behavior of GaSb. [...]

An ultra-high vacuum system for secondary electron yield measurements and electron-conditioning of particle accelerators materials at cryogenic temperatures: commissioning and first experiments / Marinoni, Stefano (Politecnico di Milano (IT))
In the Large Hadron Collider (LHC), the avalanche multiplication of electrons inside the vacuum chamber drives the build-up of an electron cloud, which can impact the performance of the accelerator as it causes a substantial heat load to the cryogenic system. The evolution of the beam pipe chemical state and secondary electron emission properties under the electron cloud activity is known as surface conditioning. [...]

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. [...]
