Dear colleagues,

snow and sun and many a charged particle have been on the programme of the school in Les Houches with 55 students from very different backgrounds. The demand for tutorials and training is permanently high, in the course of 2012 we plan to propose a  more permanent support  like the Ion Trapper's Wiki and an advanced review volume.

Best regards,
the editorial team

The groups of Eric Hudson, Svetlana Kotochigova and Hermann Uys are in the process of officially joining the Action.
