Proof of concept: The vacuum transfer in pictures (II)
After lunch and about two hours of waiting for the deposition process to end, the actual transfer of the sample can begin.
Again, the only way to move anything inside the machinery is with the transfer rods.
Then it's time for Karsten Prietzel's newly designed gripper to pick up the fresh sample.
At this point, it looks like an extra arm would be nice...
Somehow, they manage. Step one - complete.
Now the sample has to be slid onto the new sample holder.
The parts have to meet at exactly the right angle. The metal parts jam easily under vacuum, and when they do, the sample is almost certainly lost.
This is the point when Karsten Prietzel says: "Hang on, something doesn't look right." The sample is halfway on the new holder, they are beginning to loosen the gripper.
But after a few tense minutes (and a valiant push), Prietzel gives the "all clear".
The sample sits safely on its new holder.
The team is pleased…
…and on the way to Adlershof.
