A (M. H.): No, we did not. Unfortunately there was no time as we had a very strict time schedule - the tests were performed in the scope of the R&D of the Inner Tracker for HERA-B. Perhaps the term "whiskers" is a little bit misleading. These whiskers are in the plane on the MSGC substrate, they are not growing on the anode strips. It seems that theses effects have something to do with the diamond-like coating of the glass substrate.
