INTERNATIONAL WORKSHOP "COSMIC RAY ANISOTROPIES"
This interdisciplinary workshop will give a synoptic overview of the cosmic ray anisotropy observations by the large area telescopes as IceCube, Milagro, the Tibet airshower array among others, and those observed by spacecraft especially by the Voyager and Pamela spacecraft and the AMS instrument, as well as the theory and modeling efforts including that of the large scale heliosphere. The anisotropies in the cosmic ray flux appear from the high energy range (TeV) to low energy range (keV to MeV) that is in the propagation of galactic cosmic rays to the propagation of solar energetic particles as well as that of Jovian electrons. Recent Voyager observations also suggest that the low energy flux at the heliopause is anisotropic.
To describe the anisotropic transport a couple of models are discussed in literature. In the inner heliosphere focussed transport theories are used, which are solved numerically with the help of the equivalent stochastic differential equations. In the heliotail, for the high energy, the gyroradius is of the order of the cylindric diameter of the tail and thus one has to use the full orbit theory.
In addition all the transport models need as input the state of the local plasma enviroment. The latter is provided by large scale magnetohydrodynamic models.
Finallly, the transport of cosmic rays depends on the diffusion tensor, which is affected by the local magnetic field fluctuations and its turbulence. The acceleration or deceleration depends on the local structure of the shock fronts.
The positron anisotropy observed by Pamela spacecraft and the AMS instrument onboard of the ISS are another aspect of anomalies in the cosmic ray spectra, and some aspects shall be discussed with the emphasis on anisotropic distribution functions.
The workshop takes place at Physikzentrum Bad Honnef, 26 - 30 Januar 2015.

SHAOJUN XU
PhD student Shaojun Xu from University of Manchester is staying at Experimental Physics II (RUB) from January 26th-30th, 2015. He is working for the Marie Curie - Initial Training Network Reactive Atmospheric Plasma processIng (RAPID).
Working with Simon Hübner, Gert Willems, Simon Große-Kreul and other students and staffs in our group, Shaojun was here to carry out the mass spectroscopic study of UV-catalysis system, which was to study the UV photocatalysis effect for ions generation in different air humidity with and without TiO2. The ions Mass Specs and neutral Mass Specs are employed for measurement. The results was expected to show the synergistic effect between UV and TiO2 catalyst. The effect of air humidity was also discovered.
