Beam-based commissioning of a novel X-band transverse deflection structure with variable polarization
/ González Caminal, P (DESY) ; Christie, F (DESY) ; D'Arcy, R (DESY) ; Jaster-Merz, S M (DESY) ; Assmann, R (DESY) ; Burkart, F (DESY) ; Conrad, B (DESY) ; Dinter, H (DESY) ; Foese, M (DESY) ; Herrmann, J (DESY) et al.
Longitudinal electron-beam diagnostics play a critical role in the operation and control of x-ray free-electron lasers, which rely on parameters such as the current profile, the longitudinal phase space, or the slice emittance of the particle distribution. On the one hand, the femtosecond-scale electron bunches produced at these facilities impose stringent requirements on the resolution achievable with the diagnostics. [...]

/ Weikum, M K (DESY) ; Akhter, T (INFN, Naples) ; Alesini, P D (LNF, Dafne Light) ; Alexandrova, A S (Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.) ; Anania, M P (LNF, Dafne Light) ; Andreev, N E (Lebedev Inst. ; Moscow, MIPT) ; Andriyash, I (SOLEIL, Saint-Aubin) ; Aschikhin, A (DESY) ; Assmann, R W (DESY) ; Audet, T (LPGP, Orsay) et al.
Plasma accelerators present one of the most suitable candidates for the development of more compact particle
acceleration technologies, yet they still lag behind radiofrequency (RF)-based devices when it comes to beam quality,
control, stability and power efficiency. The Horizon 2020-funded project EuPRAXIA (“European Plasma Research
Accelerator with eXcellence In Applications”) aims to overcome the first three of these hurdles by developing a
conceptual design for a first international user facility based on plasma acceleration. [...]

A collaboration between DESY, PSI and CERN has been established to develop and build an advanced modular X- band transverse deflection structure (TDS) system with the new feature of providing variable polarization of the deflecting force. The prototype of the novel X-band TDS, the Polarizable X-band (PolariX) TDS, was fabricated at PSI following the high-precision tuning-free production process developed for the C-band Linac of the SwissFEL project.

Experimental demonstration of novel beam characterization using a polarizable X-band transverse deflection structure
/ Marchetti, B (DESY ; European XFEL, Hamburg) ; Grudiev, A (CERN) ; Craievich, P (PSI, Villigen) ; Assmann, R (DESY) ; Braun, H H (PSI, Villigen) ; Catalan Lasheras, N (CERN) ; Christie, F (DESY) ; D'Arcy, R (DESY) ; Fortunati, R (PSI, Villigen) ; Ganter, R (PSI, Villigen) et al.
The PolariX TDS (Polarizable X-Band Transverse Deflection Structure) is an innovative TDS-design operating in the X-band frequency-range. The design gives full control of the streaking plane, which can be tuned in order to characterize the projections of the beam distribution onto arbitrary transverse axes. [...]

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. [...]
