The joys of lab work

Lab work in the time of Covid19 (September 2020)

And we are back in the lab!!

Critical stages.

 

The cryostat is set free.
At the heart of the cryostat.
Almost there (with Eric from Semimetrics)!
All stages neatly arranged until reassembling.

 

Reassembling the cryostat after maintenance:

All wires neatly soldered back on.
The cryostat is ready to go back to work.
And we are back in (Mössbauer) business!
