[Tex/LaTex] Math Saturation Symbol

math-modesymbols

I'm searching for a math symbol that shows saturation. It looks like a slash with a horizontal line at each end.
I found a question about drawing it in a node: Saturation block

But I want to use it as a subscript in math mode.

I'm not sure if this is what you want, but you can design your own symbol without tikz. Use \mathchoice to allow for use as a subscript or subsubscript.

enter image description here

Here is the code:

\documentclass{article}
\usepackage{calc} % needed to subtract from \hght

\newlength{\wdth}
\newlength{\hght}
\newlength{\dpth}

\newcommand{\sat}{\mathchoice%
{\settowidth{\wdth}{/}\settoheight{\hght}{/}\settodepth{\dpth}{/}%
    \rule[-\dpth]{.25em}{.09ex}\hspace{-.13\wdth}/%
    \hspace{-.15\wdth}\rule[\hght-.09ex]{.25em}{.09ex}}
{\settowidth{\wdth}{/}\settoheight{\hght}{/}\settodepth{\dpth}{/}%
    \rule[-\dpth]{.25em}{.09ex}\hspace{-.15\wdth}/%
    \hspace{-.15\wdth}\rule[\hght-.09ex]{.25em}{.09ex}}   
{\settowidth{\wdth}{$\scriptstyle /$}\settoheight{\hght}{$\scriptstyle /$}\settodepth{\dpth}{$\scriptstyle /$}%
    \rule[-\dpth]{.2em}{.08ex}\hspace{-.17\wdth}\scriptstyle /%
    \hspace{-.17\wdth}\rule[\hght-.08ex]{.2em}{.08ex}} 
{\settowidth{\wdth}{$\scriptstyle /$}\settoheight{\hght}{$\scriptscriptstyle /$}\settodepth{\dpth}{$\scriptscriptstyle /$}%
    \rule[-\dpth]{.15em}{.07ex}\hspace{-.19\wdth}\scriptscriptstyle /%
    \hspace{-.19\wdth}\rule[\hght-.07ex]{.15em}{.07ex}} 
}

\begin{document}

$A\sat B_{A\sat B_{A\sat B}}$

\end{document}

If you want longer or shorter tails you can adjust the lengths in the \rule parameters. The .25em (or .2em for subscript, .18em for subsubscript) controls the length.
