What's the bottom right image of?

That is a mercury arc rectifier:

I thought you might also enjoy its German name: Quecksilberdampfgleichrichter

Sounds kinda similar to the Swedish word "kvicksilverbågelikriktare"....

EDIT: After doing some more googling, the proper name for the device in Swedish is:

"Kvicksilverlikriktare"

and sounds nothing like the hungarian "higanyív szelep" or "higanygőz egyenirányító"

Or its Dutch name:

Kwikdampgelijkrichter

It shows Cherenkov radiation of a nuclear underwater reactor (I think, I don't know this exact picture)

Nope, just plain UV from the mercury arc in the rectifier:
