Numerical simulations of energy deposition caused by 50 MeV—50 TeV proton beams in copper and graphite targets / Nie, Y (CERN) ; Schmidt, R (CERN) ; Chetvertkova, V (GSI Helmholtzzentrum für Schwerionenforschung) ; Rosell-Tarrago, G (University of Barcelona) ; Burkart, F (CERN) ; Wollmann, D (CERN)
The conceptual design of the Future Circular Collider (FCC) is being carried out actively in an international collaboration hosted by CERN, for the post–Large Hadron Collider (LHC) era. The target center-of-mass energy of proton-proton collisions for the FCC is 100 TeV, nearly an order of magnitude higher than for LHC. [...]

Non-perturbative measurement of low-intensity charged particle beams / Fernandes, M (CERN ; Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Geithner, R (Jena U. ; Helmholtz Inst., Jena) ; Golm, J (Jena U.) ; Neubert, R (Jena U.) ; Schwickert, M (Darmstadt, GSI) ; Stöhlker, T (Jena U. ; Helmholtz Inst., Jena ; Darmstadt, GSI) ; Tan, J (CERN) ; Welsch, C P (Liverpool U. ; Cockcroft Inst. Accel. Sci. Tech.)
Non-perturbative measurements of low-intensity charged particle beams are particularly challenging to beam diagnostics due to the low amplitude of the induced electromagnetic fields. In the low-energy antiproton decelerator (AD) and the future extra low energy antiproton rings at CERN, an absolute measurement of the beam intensity is essential to monitor the operation efficiency.

Characterization of 41Ar production in air at a PET cyclotron facility / Cicoria, Gianfranco (Unlisted, IT) ; Cesarini, Francesco (Unlisted, IT) ; Infantino, Angelo (CERN) ; Vichi, Sara (Bologna U.) ; Zagni, Federico (Unlisted, IT) ; Marengo, Mario (Unlisted, IT)
In the production of Positron Emission Tomography (PET) nuclides at a medical cyclotron facility 41Ar (T1/2 = 109.34 m) is produced by the activation of air due to the neutron flux, according to the 40Ar(n, γ)41Ar reaction. In this work, we describe a relatively inexpensive and readily reproducible methodology of air sampling that can be used for quantification of 41Ar during the routine production of PET nuclides.

Performance of space charge simulations using High Performance Computing (HPC) cluster / Bartosik, Hannes (CERN) ; Rumolo, Giovanni (CERN)
In 2016 a collaboration agreement between CERN and Istituto Nazionale di Fisica Nucleare (INFN) through its Centro Nazionale Analisi Fotogrammi (CNAF, Bologna) was signed [1], which foresaw the purchase and installation of a cluster of 20 nodes with 32 cores each, connected with InfiniBand, at CNAF for the use of CERN members to develop parallelized codes as well as conduct massive simulation campaigns with the already available parallelized tools.
