The following is the following but I want the text is in one column, not in two:

\subsection*{Electron Avalanche in GEM Foils}
There are several simplifications made in simulating the electron avalanche in GEM foils.
There is only multiplication from electron collision.
There is no electron lost to negative ion formation.
The space charge effects are negligible.

\begin{equation}
Q = n_{0} e M
\end{equation}

where $e$ is the electron change, and $M$ is the average \emph{gas multiplication factor} that characterizes the counter operation.
\end{document}
gives
How can you have those small numbers at the side for the review at one column?
