A collaboration between DESY, PSI and CERN has been established with the aim of developing and building an advanced X-Band transverse deflector structure (TDS) with the new feature of providing variable polarization of the deflecting force.

SL(2,$\mathbb{C}$) Gustafson Integrals [DESY-17-200; arXiv:1711.07822] Elliptic Hypergeometric Functions in Combinatorics, Integrable Systems and Physics, ViennaVienna, Austria, 20 Mar 2017 - 24 Mar 2017   It was shown recently that many of the Gustafson integrals appear in studies of the SL(2,$\mathbb{R}$) spin chain models. One can hope to obtain a generalization of the Gustafson integrals considering spin chain models with a different symmetry group [...] OpenAccess: PDF PDF (PDFA); 2018-05-1823:26 [PUBDB-2018-02013] Contribution to a conference proceedings et al A PETRA IV Lattice Based on Hybrid Seven Bend Achromats 9th International Particle Accelerator Conference, IPAC'18, VancouverVancouver, Canada, 29 Apr 2018 - 4 May 2018 , 4 pp. (2018) [10.3204/PUBDB-2018-02013]   For the PETRA IV project at DESY it is planned to convert the 6 GeV synchrotron light source PETRA III into a diffraction limited storage ring with ultra-low emittances. PETRA IV should provide a natural emittance two orders of magnitude smaller as now. [...] OpenAccess: PDF PDF (PDFA); 2018-05-1823:04 [PUBDB-2018-02009] Contribution to a conference proceedings et al Optimization of the Injection Kicker Bump Leakage at PETRA III 9th International Particle Accelerator Conference, IPAC'18, VancouverVancouver, Canada, 29 Apr 2018 - 4 May 2018 , 4 pp. (2018) [10.3204/PUBDB-2018-02009]   PETRA III is a third generation synchrotron light source at DESY delivering high brightness photon beams for users at 21 beam lines. It is operated at 6 GeV with a beam current of 100 mA in top-up mode and is in operation for users since 2010.

Multipacing in an RF Window: Simulations and Measurements 9th International Particle Accelerator Conference, IPAC’18, VancouverVancouver, Canada, 29 Apr 2018 - 4 May 2018 , 4 pp. (2018) [10.3204/PUBDB-2018-01995]   Electron guns are used in the accelerators of the European XFEL and FLASH. They are operated at 1.3 GHz.

This structure will have the novel feature of variable polarization of the deflecting mode, allowing bunches to be streaked at any transverse angle, rather than at just one angle as in a conventional cavity.

The SINBAD-ARES linac will be a conventional S-band linear RF accelerator allowing the production of low charge (0.5 pC - tens pC) ultra-short electron bunches (FWHM length ≤ fs - few fs) with 100 MeV energy.
