%The abstract.
\abstract{EUSO-Balloon is a pathfinder prefiguring the future fluorescence space telescope JEM-EUSO that should be installed on-board of the Internal Space Station before the end of this decade. 
This telescope will be the payload of a stratospheric balloon operated by CNES, starting its flight campaign in 2014.
Current technical development for JEM-EUSO are a challenge for a space project, have been implemented in EUSO-Balloon. 
In this poster, the complete design of this instrument will be presented. It consists of an advanced modular telescope structure including a set of three Fresnel lenses having an excellent focusing capability onto its pixelized focal surface of its UV Camera. This camera is very sensitive to single photons, with 6 orders of magnitude dynamic range thanks to an adaptive gain, and fast enough to observe speed-of-light phenomena. The camera is an array of multianodes photomultipliers, which dynodes are driven by Crockoft Walton HV generators capable of switching down the gain in few microseconds to protect the photodetectors against strongly luminous events.
The analog signals at anodes are digitized continuously each time window (2.5 microsecond) by an ASIC, performing two kinds of signal measurements and readout by a FPGA applying a first level trigger algorithm. 
The Electronics is operated by a digital processing unit comprising a CPU associated to Clocks generators board and a GPS receiver, an event filtering board based on a FPGA and an House-Keeping unit for the instrument monitoring. The CPU controls both acquisition and the data storage.
This processing unit is interfaced with the CNES telemetry system to receive commands from ground and to download samples of the event or monitoring data.
The whole instrument operates autonomously with a battery package that drives a series of power supply boards that deliver the required voltage to each board.

\section{Introduction}
EUSO-Ballon is a reduced scaled telescope aiming at verifying the conceptual design as well as the technologies foreseen to be applied for the construction of the future space telescope JEM-EUSO mission~\cite{bib:EUSOperf}. 
The scientific and technical goals on its mission are reviewed in the reference~\cite{bib:EBpath}. This instrument is foreseen to be operated in a standalone mode, onboard of a stratospheric balloon.
The instrument design had to be as close as possible to that of the JEM-EUSO. Nevertheless the special environmental conditions which are much more severe than in space required much precautions in the design 
and implied dedicated tests under the realisation of prototypes. 
The section~\ref{icdc}
with Fresnel Since autumn 2011, the instrument has been designed to be operated onboard a stratospheric Balloon  
d it is presently at the stage on the final assembly, integration and test.

\subsection{Equations}
Equations can be introduced without numbering

\begin{eqnarray*}
 y=a \ddot x + b \dot x + c
\end{eqnarray*}

or with numbering

\begin{equation}
 \chi^{2}= \sum\limits_{i=0}^{n}\frac{(t_{i}-t_{0}-ax_{i}-by_{i}-
 \alpha r_{i}/c)^{2}}{\sigma_{i}^{2}}
\end{equation}

The array environment can be used to introduce multiple-line
equations not to numerate:

\begin{eqnarray*}
(x+y)(x-y) & = & x^2-xy+xy-y^2 \\
           & = & x^2-y^2 \\
   (x+y)^2 & = & x^2+2xy+y^2
\end{eqnarray*}

or partly to numerate:

\begin{eqnarray}
(x+y)(x-y) & = & x^2-xy+xy-y^2 \nonumber \\
           & = & x^2-y^2 \\
   (x+y)^2 & = & x^2+2xy+y^2
\end{eqnarray}

The array environment can be used for expression of the following
type:

\[ \left( \begin{array}{c}
\left| \begin{array}{cc} x_{11} & x_{12} \\ x_{21} & x_{22}
\end{array} \right| x \\y \end{array} \right) \]

This is an example on show to add space:

\begin{equation}
f(n) = \left\{
  \begin{array}{l l}
    n/2 & \quad \textrm{if $n$ is even}\\
    -(n+1)/2 & \quad \textrm{if $n$ is odd}
  \end{array} \right.
\end{equation}

and how to remove space:

\begin{equation}
\left(\!\!
    \begin{array}{c}
      n \\
      r
    \end{array}
  \!\!\right) = \frac{n!}{r!(n-r)!}
\end{equation}

\subsection{Lists}

You may create an itemized list with the places to see in Rio de Janeiro:

\begin{itemize}
\item Copabacana Beach
\item Corcovado
\item Sugar Loaf
\end{itemize}

An enumerated list with the rhythms to listen:

\begin{enumerate}
\item Bossa Nova
\item Choro
\item Samba
\end{enumerate}

Or a customized list with the food and drinks to taste:

\begin{itemize}
\item[$\gamma$] Brigadeiro
\item[$\beta$]  Caipirinha
\item[$\alpha$] Feijoada
\end{itemize}

\subsection{Footnotes}

Footnotes can be created with the footnote command\footnote{This is
a footnote example.}.


\subsection{Figures}

Single column figures and images as in figure \ref{simp_fig}
preferred. However, large figures can be made to span two columns. If you have to introduce two column
figures(e.g., figure \ref{wide_fig}), please verify that they do not
overflow the margins of the text.

\subsection{Tables}

Tables can be done at one (Table \ref{table_single}) and two columns. \\

\begin{table}[h]

\begin{tabular}{|l|c|c|}
\hline Month & Temperature ($^\circ$C) & Precipitation (mm) \\ \hline
