Passive Hydrogen Maser teardown!
« on: October 19, 2021, 06:18:42 pm »
Just added "update 5" to http://www.leapsecond.com/maser/

It gives details on "digging down" to the cavity of the Maser.

Lots of PIX!  :)

Cheers!

Here is the "eye candy" shot of the storage bulb! :popcorn:

Your interesting pictures reminded me of my last physics project. That was building an infrared optical frequency standard using a CO2 laser stabilized by a large OsO4 absorption cell, at 30 THz. The project was abandonded without completion after in 1989 the physics nobel prize went for the development of atomic traps.
Funds got redirected to trap research. Guess there are results by now.

That video had nice glory shots of the laboratory  :popcorn:
For a more in depth technical presentation, I can recommend this from the same researcher,

held at the BIPM conference regarding the redefinition of the SI constants (26th CGPM)
