Laser treated surfaces in particle accelerators : relation between superficial topography, particle adhesion and compatibility for ultra-high vacuum applications / Baudin, Lucie
Laser-assisted surface structuration was developed at CERN for the treatment of the inside wall of the vacuum system [...]

Morphological and Chemical Characterization of Laser Treated Surface on Copper / Baudin, Lucie (CERN ; U. Evry) ; Sitko, Monika (CERN) ; Garion, Cédric (CERN) ; Chiggiato, Paolo (CERN) ; Delloro, Francesco (U. Evry) ; Gaslain, Fabrice (U. Evry) ; Sennour, Mohamed (U. Evry) ; Jeandin, Michel (U. Evry) ; Bajek, David (Dundee U.) ; Wackerow, Stefan (Dundee U.) et al.
Electron multipacting and electron cloud have been identified as being the major limiting factors for the beam quality or for the cryogenic system of high-intensity positive particles accelerators. Among conditioning operational techniques and other surface structuration techniques used to decrease the Secondary Electron Yield (SEY) of surfaces, laser surface treatment is a promising method to treat in situ and at atmospheric pressure copper surface of the vacuum chamber.

Injection and Extraction Systems for a High-Power Proton Synchrotron at CERN / Bartmann, W (CERN) ; Fedosseev, V (CERN) ; Goddard, B (CERN) ; Kramer, T (CERN)
A new High-Power Proton Synchrotron (HP-PS) is being studied at CERN for the second phase of the Long Baseline Neutrino facility (LAGUNA-LBNO) where a 2 MW beam power shall impinge onto a target. A 4 GeV H− injection based on foil stripping and extendable to laser-assisted magnet stripping is described. [...]

Lorentz laser-assisted stripping (Lolas) for $H^{-}/H^{0}$ injection into proton drivers / Gastaldi, Ugo (INFN – Laboratori Nazionali di Legnaro Via Romea 4)
We discuss the main components of schemes for Lorentz laser-assisted stripping (abbreviated Lolas henceforth) proposed for injection into proton driver accumulators: H- - H0 + e- Lorentz stripping, H0 - H0(n) laser excitation, H0(n) - p+ + e- Lorentz stripping. We mention results obtained in practice of H- beam transport and storage and of experiments addressing physics of the H- ion, of the H0 atom and of vacuum, which prove the feasibility of each Lolas component.

Quantum Signatures in Laser-Assisted Cherenkov Radiation / Avetissian, H K ; Israelyan, S S ; Mkrtchian, G F ; Sedrakian, K V
If in the spontaneous radiation processes of charged particles the medium with refractive index n>1 plays only a role of the third body, the presence of a medium at the interaction with external electromagnetic wave causes the new threshold phenomena which have an essentially nonlinear character. In the present work the case of strong laser field is considered within the scope of the relativistic quantum theory for electron-laser interaction in a medium. [...]

Influence of the surface treatment of the CMS conductor on its adhesion properties at 300 K and 4.2 K / Rondeaux, F ; Kircher, F ; Levesy, B ; Reytier, M ; Safrany, J S
In the 4 T, 12.5 m long, 6 m bore diameter superconducting solenoid for the compact muon solenoid (CMS) experiment at large hadron collider (LHC), the interfaces between the insulation and the conductor or the external cylinder are subjected to high shear forces during the cool down to 4.5 K and the operation phase up to 4 T. Due to the conductive cooling of the coil, the bonding at the different interfaces is a critical point, which is directly related to the quality of the surfaces. [...]
