Future Circular Collider Study FCC-he Baseline Parameters / Bruning, Oliver (CERN) ; Jowett, John (CERN) ; Klein, Max (University of Liverpool (GB)) ; Pellegrini, Dario (CERN) ; Schulte, Daniel (CERN) ; Zimmermann, Frank (CERN)
Initial considerations are presented on the FCC-he, the electron-hadron collider con guration within the Future Circular Collider study. This note considers arguments for the choice of the electron beam energy based on physics, ep scattering kinematics and cost. [...]

The Two-Screen Measurement Setup to Indirectly Measure Proton Beam Self-Modulation in AWAKE / Turner, Marlene (CERN ; Graz, Tech. U.) ; Biskup, B. (CERN ; Prague, Tech. U.) ; Burger, S. (CERN) ; Gschwendtner, E. (CERN) ; Mazzoni, S. (CERN) ; Petrenko, A. (CERN)
The goal of the first phase of the AWAKE experiment at CERN is to measure the self-modulation of the $\sigma_z = 12\,\rm{cm}$ long SPS proton bunch into microbunches after traversing $10\,\rm{m}$ of plasma with a plasma density of $n_{pe}=7\times10^{14}\,\rm{electrons/cm}^3$. The two screen measurement setup is a proton beam diagnostic that can indirectly prove the successful development of the self-modulation of the proton beam by imaging protons that got defocused by the transverse plasma wakefields after passing through the plasma, at two locations downstream the end of the plasma.

MD#1182: Calibration of diamond particle detectors in IP6 / Valette, Matthieu (CERN) ; Wollmann, Daniel (CERN) ; Lindstrom, Bjorn Hans Filip (Uppsala University (SE)) ; Wiesner, Christoph (CERN)
In case of an asynchronous beam dump with a fully filled LHC machine it is expected that all standard ionisation chamber Beam Loss Monitors (IC BLM) around the LHC dumping region in IP6 will be saturated. [...]

The crystal structure of (Nb0.75Cu0.25)Sn2 in the Cu-Nb-Sn system / Martin, Stefan (TU Bergakademie Freiberg) ; Walnsch, Alexander (TU Bergakademie Freiberg) ; Nolze, Gert (Federal Institute for Materials Research and Testing (BAM), Berlin) ; Leineweber, Andreas (TU Bergakademie Freiberg) ; Leaux, Floriane (CERN) ; Scheuerlein, Christian (CERN)
During the processing of superconducting Nb3Sn wire, several intermediate intermetallic phases including a previously encountered Cu-Nb-Sn phase show up. The yet unknown crystal structure of this phase is now identified by a combination of different experimental techniques and database search to be of the hexagonal NiMg2 type with a proposed composition of about (Nb0.75Cu0.25)Sn2.
