Can 21 cm Emission Be Detected in a Laboratory?

Click For Summary
SUMMARY

The discussion centers on the detection of the 21 cm emission line of atomic hydrogen in laboratory settings. Participants highlight that while this emission is prevalent in the Galaxy due to the abundance of atomic hydrogen, its laboratory detection remains uncertain. The mention of "atomic beam techniques" suggests potential advancements in reproducing this emission in controlled environments. Additionally, the hydrogen maser is identified as a practical application utilizing this transition.

Hey,

I kind of understand the process of the 21 cm emission of the atomic Hydrogen, I know how rare it should be but still it is detectable in our Galaxy due to the huge amount of atomic hydrogen it has.

However, I was wondering if it is possible to detect the 21 cm emission line in a laboratory. I couldn't find anything related to that. The only information I could find it the astronomical sources detection.

Actually, in one website they mentioned that this emission could be now reproduce in the laboratories due to the "development of atomic beam techniques." But there was no references...

Does anyone have any idea or references that could help me?

Thanks in advance

The hydrogen maser uses this transition, for example. It uses beams of hydrogen atoms.
 
Thank you!
I didn't find about the hydrogen masers before.
