Last week
we had beam time with the more powerful HITS laser.

The problem was that the
laser is too far away from our set up. We aligned the beam through 3 different
rooms. Unfortunately we lost most of the power due to the long beam path. Furthermore
the beam arrived at our set up with an elliptical shape and strange modes.

The "manipulation unit" was no longer
attached to the "movement stage" |
On
top of that we couldn’t move our grating anymore. For some reason the
manipulator for the “movement stage” fell off. Thus we had to vent the chamber
and open it to fix the stage. We decided to cancel our HITS beam time and thus
gave it back to other groups.
Next beam
time we are going back to the KLS laser.
Besides the
bad news, we finally had a free weekend with no beam time. To use this
opportunity Daniel, his roommate and I went to the Cosmosphere. It’s a museum
about rocket science and space flights.
