How spectroscopic x-ray imaging benefits from inter-pixel communication
/ Koenig, Thomas (Forschungszentrum Karlsruhe, ANKA) ; Zuber, Marcus (Forschungszentrum Karlsruhe, ANKA) ; Hamann, Elias (Freiburg U. ; Forschungszentrum Karlsruhe, ANKA) ; Cecilia, Angelica (Forschungszentrum Karlsruhe, ANKA) ; Ballabriga, Rafael (CERN) ; Campbell, Michael (CERN) ; Ruat, Marie (ESRF, Grenoble) ; Tlustos, Lukas (CERN) ; Fauler, Alex (Freiburg U.) ; Fiederle, Michael (Freiburg U. ; Forschungszentrum Karlsruhe, ANKA) et al.
Spectroscopic x-ray imaging based on pixellated semiconductor detectors can be sensitive to charge sharing and K-fluorescence, depending on the sensor material used, its thickness and the pixel pitch employed. As a consequence, spectroscopic resolution is partially lost. [...]

Charge Summing in Spectroscopic X-Ray Detectors With High-Z Sensors
/ Koenig, Thomas (Forschungszentrum Karlsruhe, ANKA) ; Procz, Simon (Freiburg U.) ; Cecilia, Angelica (Forschungszentrum Karlsruhe, ANKA) ; Ballabriga, Rafael (CERN) ; Baumbach, Tilo (Forschungszentrum Karlsruhe, ANKA) ; Llopart, Xavier (CERN) ; Fiederle, Michael (Freiburg U.) ; Zuber, Marcus (Forschungszentrum Karlsruhe, ANKA) ; Hamann, Elias (Forschungszentrum Karlsruhe, ANKA) ; Fauler, Alex (Freiburg U.) et al.
The spectroscopic performance of photon counting detectors is limited by the effects of charge sharing between neighboring pixels and the emission of characteristic X-rays. For these reasons, an event can be either missed or counted more than once. [...]

Technol.) ; Keilmann, Alexander (Karlsruhe, Inst. Technol.) ; Baumbach, Tilo (Karlsruhe, Inst. Technol.) ; Rossmanith, Robert (Karlsruhe, Inst. Technol.) ; Schoerling, Daniel (CERN)
The magnetic field in superconductive undulators is changed by varying the current in the superconductive wires. During operation at stable current, the electric current is confined to the resistance-free filaments [...]

Status of COLDDIAG: A Cold Vacuum Chamber for Diagnostics
/ Gerstl, Stefan (KIT, Karlsruhe) ; Baumbach, Tilo (KIT, Karlsruhe) ; Casalbuoni, Sara (KIT, Karlsruhe) ; Grau, Andreas (KIT, Karlsruhe) ; Hagelstein, Michael (KIT, Karlsruhe) ; Saez de Jauregui, David (KIT, Karlsruhe) ; Baglin, Vincent (CERN) ; Boffo, Cristian (Babcock Noell, Wuerzburg) ; Sikler, Gunther (Babcock Noell, Wuerzburg) ; Bradshaw, Thomas (Rutherford) et al.
One of the still open issues for the development of superconducting insertion devices is the understanding of the beam heat load. With the aim of measuring the beam heat load to a cold bore and the hope to gain a deeper understanding in the beam heat load mechanisms, a cold vacuum chamber for diagnostics is under construction.

Beam heat load measurements in the cold bore superconductive undulator in ANKA

Measurements of the beam-induced heat load in the ANKA cold-bore superconductive undulator are summarized. The strength of the two dominating effects, resistive wall heating and heating by electron bombardment, depends on the beam parameters and the gap width..

Operation of the ANKA Synchrotron Light Source with Superconductive Undulators
/ Rossmanith, Robert ; Baumbach, Tilo ; Bernhard, Axel ; Hagelstein, Michael ; Kostka, Barbara ; Steffens, Erhard ; Weisser, Matthias ; Wollmann, D
The synchrotron light source ANKA (2.5 GeV, 200 mA) is a versatile multi-purpose storage ring with beam lines for coherent IR and THz radiation (IR-laser), LIGA applications and high brilliance X-rays. It is now plannned to install in addition several superconductive undulators for a wide range of applications: fast tunable X-rays for material research, imaging applications and an undulator with variable polarization direction for a dichroism beamline.
