Strain induced irreversible critical current degradation in highly dense Bi-2212 round wire / Bjoerstad, R (CERN) ; Scheuerlein, C (CERN) ; Rikel, M.O. (Nexans SuperConductors GmbH) ; Ballarino, A (CERN) ; Bottura, L (CERN) ; Jiang, J (Florida State University) ; Matras, M (Florida State University) ; Sugano, M (KEK) ; Hudspeth, J (ESRF) ; Di Michiel, M (ESRF)
The strain induced critical current degradation of overpressure processed straight Bi 2212/Ag wires has been studied at 77 K in self-field. For the first time superconducting properties, lattice distortions, composite wire stress and strain have been measured simultaneously in a high energy synchrotron beamline. [...]

Beam feasibility study of a collimator with in-jaw beam position monitors / Wollmann, Daniel (CERN) ; Nosych, Andriy A (CERN ; Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.) ; Valentino, Gianluca (CERN) ; Aberle, Oliver (CERN) ; Aßmann, Ralph W (CERN) ; Bertarelli, Alessandro (CERN) ; Boccard, Christian (CERN) ; Bruce, Roderik (CERN) ; Burkart, Florian (CERN) ; Calvo, Eva (CERN) et al.
At present, the beam-based alignment of the LHC collimators is performed by touching the beam halo with both jaws of each collimator. This method requires dedicated fills at low intensities that are done infrequently and makes this procedure time consuming. [...]
