Contribution of IFJ PAN to the construction of the WENDELSTEIN 7-X stellarator (continuation 2010-2012)

Abstract

The Wendelstein 7-X stellarator is now being assembled at the Max Planck Institute for Plasma Physic (IPP), Greifswald, Germany (branch of MP IPP Garching). The Agreement on Cooperation between the MP IPP and the Henryk Niewodniczański Institute of Nuclear Physics Polish Academy of Sciences in Krakow (IFJ PAN) was signed in 2007. Within that agreement IFJ PAN has taken over the following tasks: 1. to assembly of the bus bar system powering the superconducting coils of the stellarator; 2. to take a part in design of equipment for handling, transportation and assembly of outer vessel; 3. to manufacture 30 sets of mechanics for polichromators used in plasma diagnostics; 4. to connect the bus bar systems between modules (at so called Module Separation Planes). The Task No 2 was completed in 2008, tasks No 1 and 3 – in 2011 and the Task No 4 - in 2012. General scope of the tasks 1, 2, 3 and the detail description of work done in 2008 – 2009 were presented in [1], [2], [3]. Work done in 2010 – 2011 was periodically reported in [4], [5].
