Laser Engineered Surface Structures for Custom Design of Secondary Electron Yield / Bajek, David (U. Dundee) ; Wackerow, Stefan (U. Dundee) ; Sitko, Monika (CERN) ; Calatroni, Sergio (CERN) ; Girolama, Beniamino Di (CERN) ; Abdolvand, Amin (U. Dundee)
Secondary Electron Yield (SEY) [3, 5] occurs in a system when a primary electron impinges a material's surface and induces the emission of a 1 st and potentially 2 nd generation secondary electrons (see Figure 1, Left). The total number of secondary electrons per primary electron is the SEY. [...]

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.

Role of surface microgeometries on electron escape probability and secondary electron yield of metal surfaces / Bajek, D (U. Dundee) ; Wackerow, S (U. Dundee) ; Zanin, D A (CERN) ; Baudin, L (CERN) ; Bogdanowicz, K (CERN) ; Valdivieso, E Garcia-Tabares (CERN) ; Calatroni, S (CERN) ; Di Girolamo, B (CERN) ; Sitko, M (CERN) ; Himmerlich, M (CERN) et al.
The influence of microgeometries on the Secondary Electron Yield (SEY) of surfaces is investigated. Laser written structures of different aspect ratio (height to width) on a copper surface tuned the SEY of the surface and reduced its value to less than unity. [...]

First Beam Test of Laser Engineered Surface Structures (LESS) at Cryogenic Temperature in CERN SPS Accelerator / Salemme, Roberto (CERN ; Euratom, St. Paul Lez Durance) ; Abdolvand, Amin (Dundee U.) ; Baglin, Vincent (CERN) ; Calatroni, Sergio (CERN) ; Chiggiato, Paolo (CERN) ; Di Girolamo, Beniamino (CERN) ; Garcia-Tabares Valdivieso, Elisa (CERN) ; Jenninger, Berthold (CERN) ; Prever-Loiri, Laurent (CERN) ; Sitko, Monika (CERN) et al.
Electron cloud mitigation is an essential requirement for accelerators of positive particles with high intensity beams to guarantee beam stability and limited heat load in cryogenic systems. Laser Engineered Surface Structures (LESS) are being considered, within the High Luminosity upgrade of the LHC collider at CERN (HL-LHC), as an option to reduce the Secondary Electron Yield (SEY) of the surfaces facing the beam, thus suppressing the electron cloud phenomenon.

Towards the Implementation of Laser Engineered Surface Structures for Electron Cloud Mitigation / Sitko, Monika (CERN) ; Abdolvand, Amin (Dundee U.) ; Baglin, Vincent (CERN) ; Bajek, David (Dundee U.) ; Calatroni, Sergio (CERN) ; Chiggiato, Paolo (CERN) ; Colling, Miriam (Daresbury) ; Di Girolamo, Beniamino (CERN) ; Garcia-Tabares Valdivieso, Elisa (CERN) ; Jones, Thomas (Daresbury) et al.
The LHC operation has proven that the electron cloud could be a significant limiting factor in machine performance, in particular for future High Luminosity LHC (HL-LHC) beams. Electron clouds, generated by electron multipacting in the beam pipes, leads to beam instabilities and beam-induced heat load in cryogenic systems. [...]

Qualification of Fin-Type Heat Exchangers for the ITER Current Leads / Ballarino, A (CERN) ; Bauer, P (Euratom, St. Paul Lez Durance) ; Bordini, B (CERN) ; Devred, A (Euratom, St. Paul Lez Durance) ; Ding, K (Hefei, Inst. Plasma Phys.) ; Niu, E ; Sitko, M (CERN) ; Taylor, T ; Yang, Y (Southampton U.) ; Zhou, T (Hefei, Inst. Plasma Phys.)
The ITER current leads will transfer large currents of up to 68 kA into the biggest superconducting magnets ever built. Following the development of prototypes and targeted trials of specific manufacturing processes through mock-ups, the ASIPP (Chinese Institute of Plasma Physics) is preparing for the series fabrication.

Analytical Formulation of Ic Dependence on Torsion of YBCO and BSCCO Conductors / Fleiter, J (Joseph Fourier U. ; CERN) ; Sitko, M (CERN) ; Ballarino, A (CERN)
The behavior of HTS tapes under torsion is of key importance for the definition of the allowable twist during cabling activity. In this paper, we report on the elaboration of selfconsistent analytical expressions of Ic dependence on twist pitch for YBCO and BSCCO (2223) conductors. [...]
