Although it looked like it's never going to happen and although my bosses are still not really aware of it, I am back in Erlangen... Let's see how long I can stay without the detector blowing up or the project getting at a standstill because nobody is around who has a clue (right now I have a competent substitute, but he will be in Hamburg for only a few days. The next possible substitute is not yet aware of having the responsibility about the whole detector. I have warned him that everything will be on him and he should shout NO as soon as possible, but he thought that was a joke...)
