Comments:
========
2. Tunnel and Building Grounding:
   - Grounding rings have been introduced in every level of the injector
     complex, not just in the fundament. This makes a good ground grid. (JPJ)
   - The entry holes have disappeared in the XTL floor plates. Since it is
     quite practical to access the cables without disturbing tunnel traffic,
     they should be reintroduced -> T.Hott. (JPJ)
   - The mockup tunnel will be used to test pulse cable installation. (HJE)
   - The current in the tunnel wall remesh will not be more than a few A. (HJE)
   - N.Ngada has to finish his diploma work before the end of July -> present
     that on the next meeting.

4. AOB:
   - It was suggested to limit the meeting to 1 hour = 1 topic and to rather
     have it more often. This was unanimously agreed.

Next meeting: Mon 10/07/06 11:00 30b/459
