[time-nuts] Holiday Hydrogen Glow!

[Magnus Danielson]

Dana,

The glow is a side-effect of the plasma. The primary use in H-maser is
to split H2 gad into separate H atoms before sent through a
state-separating hexapole magnet, known as A-field magnet.

In Rubidium oscillators, you achieve the same plasma glow, but then it
is the D-line emission which is the primary goal, where the D1 and D2
lines is dominant and one of them is filtered.

For hydrogen, the D-line is way up in 121,6 nm rather than 794 nm and
780 nm of rubidium, so it's not the D-line glow we see from the hydrogen
atom.

So, the same glow have separate uses and mechanisms.

Cheers,
Magnus
