In the framework of the Ion Cyclotron (IC) antenna design, ITER Organization requested qualification tests on sliding Radio-Frequency (RF) contacts, to verify that these contacts (quality class 1) are designed appropriately to guarantee a sufficient operational life time. These RF contacts will be integrated into the antenna structure at different …

In the ITER equatorial ports containing ICRH antennas, parasitic electrical resonances can be excited in the nominal 20 mm clearance gap between the port walls and the plug contained within it. RF calculations have established that these resonances can be effectively mitigated by a series of suitably located electrically conducting contacts between…

The unoccupied density of states is simulated for two different experimentally determined C 60 crystal structures. Several theoretical crystal structures are constructed to allow the effects of bond length and relative molecular orientation to be studied. It is found that both have an effect on the unoccupied states, and that the larger effect is c…
