The PolariX TDS (Polarizable X-Band Transverse Deflection Structure) is an innovative TDS-design operating in the X-band frequency-range. design gives full control of streaking plane, which can be tuned order to characterize projections beam distribution onto arbitrary transverse axes. This novel feature opens up new opportunities for detailed characterization electron beam. In this paper we present first measurements Polarix at FLASHForward beamline DESY, including three-dimensional...
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 current profile, longitudinal phase space, or slice emittance particle distribution. On one hand, femtosecond-scale electron bunches produced at these facilities impose stringent requirements resolution achievable with diagnostics. other, research development novel accelerator technologies beam-driven plasma-wakefield accelerators (PWFA)...

A collaboration between DESY, PSI and CERN has developed built an advanced modular X-band transverse deflection structure (TDS) system with the new feature of providing variable polarization deflecting force. The prototype novel TDS, polarizable (PolariX) was fabricated at following high-precision tuning-free production process for C-band Linac SwissFEL project. Bead-pull rf measurements were also performed to verify, in particular, that dipole fields does not have any rotation along...
Self-mutilative behavior (SMB) is presented as a specific form of inwardly directed aggressiveness which thought to be associated with problems impulse control. Conceptual concerning impulsivity and impulsive aggression are discussed. Among different forms dyscontrolled behavior, SMB special heuristic interest because distinction can made between patients committing those premeditated self-harming actions. Psychometric biological measures were assessed in self-mutilators comparison...
This paper details the development of a single-shot diagnostic technique for 4D average and core phase space densities low-charge, high-brightness electron beams, based on analysis shadow point-projection images metal grids. is similar to standard pepper pot method, although it allows much greater transmission beam therefore more suitable low-charge beams. Transverse coupling terms are included in analysis, allowing complete transverse matrix be reconstructed. The information extremely...

Pediatric burn care is highly variable nationwide. Standardized quality and performance benchmarks are needed for guiding improvement within pediatric centers. A network of centers was established to develop evaluate pediatric-specific best practices. multi-disciplinary team including surgeons, nurses, advanced practice providers, intensivists, rehabilitation staff, child psychologists from five a collaborative share compare data, outcomes, exchange In December 2016, the Injury Quality...
We have developed a new chromatic compensation scheme for the electron storage ring with two low-beta interaction regions in Electron-Ion Collider. The hybrid consists of modular matching periodic systems and beamlines. first-order chromatically matched solutions are linearly parameterized local linear chromaticities that control higher order beatings. parameterization enables an efficient optimization dynamic aperture. As result, we successfully achieve 1% design criterion momentum aperture ring.
