\begin{abstract}
  The purpose of Rapid Communications section is rapid publication of
  new research results which have impact in one of the fields covered
  by Plasma and Fusion Research. Authors should download the sample text
  and prepare their manuscript in the same format. The publication will be
  determined by only one review.

%%%%% MAIN TEXT %%%%%

The articles intended to be published in Rapid Communications section
should be short without attempting the completeness as required for a
regular paper.  The length of the manuscript must not exceed 2
pages in this format.  The paper size must be A4 ($21.0\,\mathrm{cm}
\times 29.7\,\mathrm{cm}$).

Authors using \LaTeX\ should use the \texttt{pfr} package provided
by the society:
\begin{quote}
  \verb|\usepackage{pfr}|
\end{quote}
Text should be typeset in Times.  The title % and the \textsf{\bfseries Keywords} 
heading should be in Times Bold.  These fonts can be 
accessed by using either the standard \texttt{times}, \texttt{mathptmx}
or recent \texttt{txfonts} package, as in
\begin{quote}
\verb|\documentclass| \\
\verb|  [a4paper,twocolumn,fleqn]{article}| \\
\verb|\usepackage{amsmath}  %| \textit{optional} \\
\verb|\usepackage{txfonts}  %| \textit{or} \texttt{times} \\
\verb|\usepackage{graphicx} %| \textit{optional}  \\
\verb|\usepackage{pfr}| \\
\verb|\begin{document}| \\
\ldots
\end{quote}
The default Computer Modern fonts may be used as a last resort.

The document should be submitted in PDF format (or PostScript
format).  Any fonts other than the standard PostScript fonts
(such as Times and Symbol) must be embedded in the document,
and don't use national (e.g.\ Japanese) fonts.

The manuscript must include a concise abstract (less than 200 words),
a complete list of references, figures and tables with captions.
Each author's name is given in the order of first name, initial of
optional middle name and last name, as in Carl F.\@ GAUSS.  References
are cited as \cite{Kru}, \cite{Spi,Tan}, and \cite{Kru,Spi,Tan}, and are 
listed at the end of the manuscript, \textit{not} preceded by a header
such as ``References.''  See also Fig.~\ref{fig:somefig} and its caption.

  \fbox{Sample Figure}
  \caption{Sample figure. Letters in figures must be sufficiently large.}
  \label{fig:somefig}
\end{figure}

Equations should be indented by 10\,mm from the left margin, as is
\begin{equation}
   \tilde{f}(\mathbf{x},\mu,E) =
 - \mbox{\boldmath$\rho$} \cdot \nabla f_\mathrm{M}(\mathbf{x},E).
\end{equation}
Vector expressed by a Greek font should be written in Greek Bold; e.g.,
$\mbox{\boldmath$\rho$}=\mathbf{b} \times \mathbf{v}_\perp/\Omega$.
For equations separated into multiple lines, the equation number should appear
only on the last line.
