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.

A New Spherical Pulse Compressor Working with Degenerated "Whispering Gallery" Mode / Li, Zongbin (SINAP, Shanghai ; Beijing, GUCAS) ; Fang, Wencheng (SINAP, Shanghai) ; Grudiev, Alexej (CERN) ; Gu, Qiang (SINAP, Shanghai) ; Zhao, Zhentang (SINAP, Shanghai)
This paper introduces a new design concept of spherical pulse compressor. The main characteristics of this new design can be described as: spherical storage cavity, degenerated “Whispering Gallery” mode and a compact mode launcher..

Particle identification of neutral particles at LHCb / Quintana, Boris (Clermont-Ferrand U.) /LHCb
Important analyses of the core LHCb physics program rely on calorimetry to identify photons, high-energy neutral pions and electrons. For this purpose, the LHCb calorimeter system is composed of a scintillating pad plane, a preshower detector, an electromagnetic and a hadronic sampling calorimeters. [...]

Study of heavy-flavour hadron decay electrons as a function of charged-particle multiplicity in pp collisions at $\sqrt{s} =$ 13 TeV with ALICE / Acharya, Shreyasi (Calcutta, VECC) /ALICE
The study of the multiplicity dependence of heavy-flavour hadron production in pp collisions provides insight into heavy quark production mechanisms and into the interplay between hard and soft processes in particle production. Further, multiple parton interactions may also play a significative role in the heavy-flavour production at LHC energies. [...]

Search for $t\bar t H$ production in high-$p_\mathrm{T}$ regimes with the ATLAS detector / Biondi, Silvia (INFN, Bologna ; U. Bologna, DIFA) /ATLAS
The associated production of the Higgs boson with a pair of top/anti-top quarks ($t\bar t H$) is the only process providing the direct access to the measurement of the Yukawa coupling between the Higgs boson and the top quark. The presented results exploit the data collected during 2015 and 2016 by the ATLAS experiment during LHC collisions at a center-of-mass energy of 13 TeV. [...]

Compression of a mixed antiproton and electron non-neutral plasma to high densities / Aghion, Stefano (Milan Polytechnic ; INFN, Milan) ; Amsler, Claude (Stefan Meyer Inst. Subatomare Phys.) ; Bonomi, Germano (Brescia U. ; INFN, Pavia) ; Brusa, Roberto S (Trento U. ; INFN, Trento) ; Caccia, Massimo (INFN, Milan ; Insubria U., Como) ; Caravita, Ruggero (Genoa U. ; INFN, Genoa) ; Castelli, Fabrizio (INFN, Milan ; Milan U.) ; Cerchiari, Giovanni (Heidelberg, Max Planck Inst.) ; Comparat, Daniel (LAC, Orsay) ; Consolati, Giovanni (Milan Polytechnic ; INFN, Milan) et al.
We describe a multi-step “rotating wall” compression of a mixed cold antiproton–electron non-neutral plasma in a 4.46 T Penning–Malmberg trap developed in the context of the AEḡIS experiment at CERN. Such traps are routinely used for the preparation of cold antiprotons suitable for antihydrogen production. [...]

Characterization of the 1S–2S transition in antihydrogen / Ahmadi, M (Liverpool U.) ; Alves, B X R (Aarhus U.) ; Baker, C J (Swansea U.) ; Bertsche, W (Manchester U. ; Cockcroft Inst. Accel. Sci.

In 1928, Dirac published an equation that combined quantum mechanics and special relativity. Negative-energy solutions to this equation, rather than being unphysical as initially thought, represented a class of hitherto unobserved and unimagined particles—antimatter. [...]

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. [...]
