2. 16. Nuclear motion in molecular ions studied with synchrotron radiation and multicoincidence momentum imaging spectrometry

   Author : Joakim Laksman; Synkrotronljusfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecule; synchrotron;

   Abstract : A momentum imaging spectrometer optimized for photoionization experiments with synchrotron radiation was built in 2008. The spectrometer is equipped with an electrostatic lens, that focuses the charged dissociation products on to a position-sensitive multi-hit delay line anode. READ MORE

4. 17. Studies of X-Ray Optics And Polarimetry For Synchrotron Radiation

   Author : Walan Grizolli; Lunds universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray optics; polarimetry; synchrotron radiation instrumentation.;

   Abstract : Synchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies have made possible to obtain very low emittance electron beams, which together with the use of undulators allow to guide a very high photon flux into a very small beam size required by the experiments.

6. 19. Simulation and analysis of radiation from runaway electrons

   Author : Mathias Hoppe; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tokamak; runaway electrons; synthetic diagnostics; fusion; synchrotron radiation; plasma physics; bremsstrahlung;

   Abstract : Electron runaway constitutes one of the primary threats to future tokamak fusion reactors such as ITER. Successful prevention and mitigation of runaways relies on the development of theoretical models which accurately describe the dynamics of runaway electrons, and these models must in turn be validated in experiments.

7. 20. Higher harmonic cavities at 3rd generation synchrotron light sources

   Author : Mattias Georgsson; Lunds universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Double RF system; Electron storage ring; Instabilities; Landau damping; Beam lifetime; Physics; Synchrotron radiation; Fysik;

   Abstract : Synchrotron radiation is a tool widely used in science. It is produced by electron accelerators called storage rings. With the high performance of the 3rd generation synchrotron light sources, the scientific results are excellent. It is important to identify and overcome the limitations of a storage ring in order to enhance its performance. READ MORE
