The ELENA facility / Bartmann, Wolfgang (CERN) ; Belochitskii, Pavel (CERN) ; Breuker, Horst (CERN) ; Butin, Francois (CERN) ; Carli, Christian (CERN) ; Eriksson, Tommy (CERN) ; Oelert, Walter (Mainz U.) ; Ostojic, Ranko (CERN) ; Pasinelli, Sergio (CERN) ; Tranquille, Gerard /ELENA ; AD
The CERN Antiproton Decelerator (AD) provides antiproton beams with a kinetic energy of 5.3 MeV to an active user community. The experiments would profit from a lower beam energy, but this extraction energy is the lowest one possible under good conditions with the given circumference of the AD. [...]

Simulations of an energy dechirper based on dielectric lined waveguides / Nie, Y. (CERN) ; Xia, G. (Manchester U. ; Cockcroft Inst. Accel. Sci. Tech.) ; Pacey, T. (Manchester U. ; Cockcroft Inst. Accel. Sci. Tech.)
Terahertz frequency wakefields can be excited by ultra-short relativistic electron bunches travelling through dielectric lined waveguide (DLW) structures. These wakefields can either accelerate a witness bunch with high gradient, or modulate the energy of the driving bunch. [...]

The PSD CBM Supermodule Response Study for Hadrons in Momentum Range 2 – 6 GeV/c at CERN Test Beams / Finogeev, D (Moscow, INR) ; Golubeva, M ; Guber, F (Moscow, INR) ; Ivashkin, A (Moscow, INR) ; Izvestnyy, A (Moscow, INR) ; Karpushkin, N (Moscow, INR) ; Morozov, S (Moscow, INR) ; Reshetin, A (Moscow, INR)
The Projectile Spectator Detector (PSD) will be used at the Compressed Baryonic Matter (CBM) experiment at FAIR to measure the centrality and orientation of the reaction plane in heavy-ion collisions. A study of PSD supermodule response at proton and pion momentum range 2 – 6 GeV has been done at the CERN T10 beam line. [...]

A Beam Dump Facility (BDF) at CERN – The Concept and a First Radiological Assessment / Ahdida, Claudia Christina (CERN) ; Casolino, Mirkoantonio (The Barcelona Institute of Science and Technology (BIST) (ES)) ; Avigni, Pietro (CERN) ; Calviani, Marco (CERN) ; Busom Descarrega, Josep (CERN) ; Canhoto Espadanal, Joao Pedro (CERN) ; Grenard, Jean-Louis (CERN) ; Jacobsson, Richard (CERN) ; Kershaw, Keith (CERN) ; Lamont, Mike (CERN) et al.
The Beam Dump Facility (BDF) Project, currently in its design phase, is a proposed general-purpose fixed target facility at CERN, dedicated to the Search for Hidden Particles (SHiP) experiment in its initial phase and whose aim is to fully absorb the high intensity 400 GeV/c SPS beam. The BDF target complex would be located underground at a depth of about 10 m and is designed to contain most of the cascade generated by the primary beam interaction. [...]
