Development of an High Gradient Side Coupled Cavity for PROBE / Pitman, Sam (Cockcroft Inst. Accel. Sci. Tech. ; Lancaster U. (main)) ; Apsimon, Robert (Cockcroft Inst. Accel. Sci. Tech. ; Lancaster U. (main)) ; Burt, Graeme (Cockcroft Inst. Accel. Sci. Tech. ; Lancaster U. (main)) ; Catalán Lasheras, Nuria (CERN) ; Grudiev, Alexej (CERN) ; Owen, Hywel (Cockcroft Inst. Accel. Sci. Tech. ; U. Manchester (main)) ; Wuensch, Walter (CERN)
The PROBE project aims to develop a high gradient proton accelerator for protons with energy around 250-350 MeV for proton radiography. Detailed studies have shown that the optimum design is a side coupled cavity at S-band. [...]

Study of the Electron Beam Transfer Line for the AWAKE RUN II Experiment at CERN / Kim, Seong-Yeol (UNIST, Ulsan) ; Chung, Moses (UNIST, Ulsan) ; Dayyani, Mohsen (IPM, Tehran) ; Döbert, Steffen (CERN)
Proton Beam-Driven Plasma Wakefield Accelerator (PBD-PWFA) has been actively investigated at CERN within the AWAKE experiments to study the electron beam acceleration using plasma wake fields of the order of GV/m. In the AWAKE RUN 1 experiment an electron beam with an energy of 19 MeV and a bunch length of 2.2 ps rms has been used for the first demonstration of electron beam acceleration in the plasma wake fields.

Performance and quench characteristics of a pancake coil wound with the 2G YBCO Roebel cable / Zhang, Qingbo (U. Southampton (main)) ; Yang, Yifeng (U. Southampton (main)) ; Young, Edward (U. Southampton (main)) ; Cavalucci, Lorenzo (U. Bologna (main)) ; Kario, Anna (KIT, Karlsruhe) ; Goldacker, Wilfried (KIT, Karlsruhe) ; Usoskin, Alexander (Unlisted, DE) ; Bottura, Luca (CERN)
The YBCO Roebel cable is a promising option for the high-energy accelerator magnets and tokamak devices with high-current carrying capability and compactness. Referring to the complex current sharing and normal zone propagation, it is difficult to apply the traditional superconductor quench measurement methodology to such a long Roebel cable (2 m) in an adiabatic condition.

Impact of the Resistive Core on Losses in Superconducting Rutherford Cables: Analysis With the Continuum Model / Breschi, Marco (U. Bologna (main)) ; Musso, Andrea (U. Bologna (main)) ; Ballarino, Amalia (CERN) ; Bottura, Luca (CERN)
Rutherford cables for particle accelerator magnets can be subjected to a time-varying magnetic field during the typical accelerator operating cycle, which in turn induces coupling currents flowing in the loops formed at the contacts between different strands. A proper analysis of the losses generated by these currents must be carried out for the design of the cryogenic system. [...]

Radiation Levels and Saturation Effects in the Electromagnetic Calorimeter of Future Linear Colliders / Sailer, Andre (CERN)
For the design of the electromagnetic calorimeter (ECal) of a future linear collider the required dynamic range for the possible readout options and the expected radiation doses have to be known. High energy electromagnetic showers are simulated to estimate the required dynamic range for a scintillator-pad based ECal read out with silicon photo-multipliers. [...]
