/ Muggli, Patric (Munich, Max Planck Inst.) ; Amorim, Ligia (Lisbon, IST) ; Karsch, Stefan (Garching, Max Planck Inst.) ; Lopes, Nelson (Lisbon, IST) ; Vieira, Jorge (Lisbon, IST)
The AWAKE experiment recently approved at CERN will study the acceleration of an externally injected electron bunch in a plasma wakefield accelerator (PWFA) driven by a self-modulated proton bunch. We study the possibility of injecting a bunch created by a laser-driven plasma wakefield accelerator (LWFA). [...]

/IS634 Collaboration
The lattice location of ion implanted radioactive 24Na (t1/2=14.96 h) in GaN and AlN was determined using the emission channeling technique at the ISOLDE/CERN facility. In the room temperature as-implanted state in both GaN and AlN, the majority of the sodium atoms are found on interstitial sites near the octahedral position, with a minority on cation Ga or Al substitutional sites.

Shaping trailing beams for beam loading via beam-induced-ionization injection at FACET
/ Amorim, Lígia Diana (SUNY, Stony Brook) ; Vafaei-Najafabadi, Navid (SUNY, Stony Brook) ; Emma, Claudio (SLAC) ; Clarke, Christine I (SLAC) ; Green, Selina Z (SLAC) ; Storey, Doug (SLAC) ; White, Glen (SLAC) ; O'Shea, Brendan (SLAC) ; Hogan, Mark J (SLAC) ; Yakimenko, Vitaly (SLAC) et al.
Recent progress in plasma based accelerator technology has demonstrated its ability to deliver high energy (GeV) beams in compact structures (centimeter to meter scale plasmas). Current developments of that technology are oriented toward producing beams with quality and energy spread comparable to those obtained using standard accelerating structures. [...]

Producing multi-coloured bunches through beam-induced ionization injection in plasma wakefield accelerator
/ Vafaei-Najafabadi, N (Stony Brook U.) ; Amorim, L D (Stony Brook U.) ; Adli, E (Oslo U.) ; An, W (UCLA) ; Clarke, C I (SLAC) ; Clayton, C E (UCLA) ; Corde, S (Palaiseau, Lab. Opt. Appl.) ; Gessner, S (CERN) ; Green, S Z (SLAC) ; Hogan, M J (SLAC) et al.
This paper discusses the properties of electron beams formed in plasma wakefield accelerators through ionization injection. In particular, the potential for generating a beam composed of co-located multi-colour beamlets is demonstrated in the case where the ionization is initiated by the evolving charge field of the drive beam itself.

Beam-driven plasma wakefield acceleration (PWFA) has demonstrated significant progress during the past two decades of research. The new Facility for Advanced Accelerator Experimental Tests (FACET) II, currently under construction, will provide 10 GeV electron beams with unprecedented parameters for the next generation of PWFA experiments.

/ISOLDE
Using radioactive isotopes produced at the CERN-ISOLDE facility, the lattice location of the implanted transition metal (TM) ions $^56$Mn, $^59$Fe and $^65$Ni in n-type single-crystalline hexagonal 6H-SiC was studied by means of the emission channeling technique. TM probes on carbon coordinated tetrahedral interstitial sites ($T_C$) and on substitutional silicon sites ($S_{Si,h+k}$) were identified. [...]

We have investigated the lattice location of implanted transition metal (TM) 56Mn, 59Fe and 65Ni ions in undoped single-crystalline cubic 3C–SiC by means of the emission channeling technique using radioactive isotopes produced at the CERN-ISOLDE facility. We find that in the room temperature as-implanted state, most Mn, Fe and Ni atoms occupy carbon-coordinated tetrahedral interstitial sites (TC). [...]

The AWAKE Collaboration has been formed in order to demonstrate proton-driven plasma wakefield acceleration for the first time. This acceleration technique could lead to future colliders of high energy but of a much reduced length when compared to proposed linear accelerators. [...]

Direct observation of the lattice sites of implanted manganese in silicon

/IS453 Collaboration ; EC-SLI Collaboration
We have studied the influence of electronic doping on the preferred lattice sites of implanted 61Co, and the related stabilities against thermal annealing, in silicon. Using the beta- emission channeling technique we have identified Co on ideal substitutional (ideal S) sites, sites displaced from bond-centered towards substitutional (near-BC) sites and sites displaced from tetrahedral interstitial towards anti-bonding (near-T) sites.
