In summary, the symbol in question, a capital 'V' with a horizontal cross bar, stands for "volume of ion production region (m3)" in a NASA paper from 1984. It can be found in the glossary on page 30 and is used in equation (12).

I've run across a symbol on a NASA paper from 1984 that I am not familiar with and that I could not find in a web search.

It's a capital 'V' with a horizontal cross bar through its center. Any ideas?

Was it an inverted upper case A? If so it might be the logic symbol meaning "for all".

Can you post an image of this symbol or provide a link to the paper?

Did it look like this?
$$\forall$$

What's it mean?

It means "for each" or "for all".

Well, with what I've been doing, I had become accustomed to the nomenclature of a paper being right up there by the introduction or abstract. So, I finally came to the end of this NASA paper and discovered - ta daaa!

The nomenclature.

So, the symbol, V with a horizontal cross-bar (duplicated by going into Word, or some such, typing a capital V and clicking the strike-through button), anyway, that symbol stands for, "Volume of ion production region (m3)."

Still trying to learn what that is - I am, by no means, really understanding more than the concepts of this paper - so, I don't know what that is, though I kind of have a guess.

Nice. You give us a 125 page document but no hint on what page to look for your symbol.

Just skimmed through it, there's a symbol matching his description first appearing at the bottom of page 30, in equation (12). Can't work out what it means though -- it appears again on page 38.

EDIT: Just checked the glossary at the bottom. It means "volume of ion production region", measured here in cubic metres.

EDIT 2: According to post #7, the OP has already discovered this...
