Res.) ; Boonpornprasert, Prach (DESY, Zeuthen) ; Brinkmann, Reinhard (DESY) ; Chen, Ye (DESY, Zeuthen) ; Engel, Johannes (DESY, Zeuthen) ; Good, James (DESY, Zeuthen) ; Gross, Matthias (DESY, Zeuthen) ; Grüner, Florian (U. Hamburg (main) ; CFEL, Hamburg) ; Huck, Holger (DESY, Zeuthen) et al.
Particle-beam-driven plasma wakefield acceleration (PWFA) enables various novel high-gradient techniques for powering future compact light-source and high-energy physics applications. Here, a driving particle bunch excites a wakefield response in a plasma medium, which may rapidly accelerate a trailing witness beam. [...]

Characterization of Self-Modulated Electron Bunches in an Argon Plasma

The self-modulation instability is fundamental for the plasma wakefield acceleration experiment of the AWAKE (Advanced Wakefield Experiment) collaboration at CERN where this effect is used to generate proton bunches for the resonant excitation of high acceleration fields. Utilizing the availability of flexible electron beam shaping together with excellent diagnostics including an RF deflector, a supporting experiment was set up at the electron accelerator PITZ (Photo Injector Test facility at DESY, Zeuthen site), given that the underlying physics is the same. [...]

High Gradient Pulsed Quadrupoles for Novel Accelerators and Space Charge Limited Beam Transport
/ Tenholt, Carmen (CERN) ; Loisch, Gregor (DESY, Zeuthen) ; Marchetti, Barbara (DESY) ; Stephan, Frank (DESY, Zeuthen)
Novel acceleration schemes like plasma wake-field based accelerators demand for high gradient focusing elements to match the Twiss parameters in the plasma to the transport lattice of the conventional accelerator beamlines, with typically much higher beta-functions. There are multiple candidates for achieving high gradient focusing fields, each one having certain drawbacks. [...]

First Experiences with the PITZ Plasma Cell for Electron Beam Self-modulation Studies
/ Groß, Matthias (DESY, Zeuthen) ; Donat, Alexander (DESY, Zeuthen) ; Good, James (DESY, Zeuthen) ; Khojoyan, Martin (DESY, Zeuthen) ; Koss, Gerald (DESY, Zeuthen) ; Krasilnikov, Mikhail (DESY, Zeuthen) ; Schütze, Rico (DESY, Zeuthen) ; Stephan, Frank (DESY, Zeuthen) ; Vashchenko, Grygorii (DESY, Zeuthen) ; Brinkmann, Reinhard (DESY) et al.
The self-modulation of long particle beams in a plasma has recently gained interest in light of the ongoing preparation for the plasma wakefield acceleration experiment of the AWAKE collaboration at CERN. Instrumental to the experiment is the self-modulation of a proton beam to generate bunches short enough for producing high acceleration fields. [...]
