Pre-conditioned flash lamps in place

As for the replacement from old to new flash lamps in the PIV laser, we now had a third batch of lamps to install. Replacing these lamps is a risky business for various reasons, not only the need of climbing the tunnel but also the actual replacing these delicate (easy to break) filaments. And when the fourth (final) lamp was to be inserted - i broke! A word signaling a problem was heard from the tunnel top and it was immediately clear that something had gone wrong. Immediately checking with Litron people, however gave some hope in that it might work with one of the non-conditioned lamps in tandem with a pre-conditioned one. Some more work and then a final test - it worked. So, now we have a laser with a complete set of flash lamps. We now only have to align the thing to optimize the set-up for maximum power output.
