+						The muon beam line of COMET Phase-I includes the pion capture
+						section and the muon transport section up to the end of first
+						$90^o$ bend. A high solenoidal field of 5 T is used in the pion
+						capture section to capture as many pions as possible. Pions and
+						muons - produced when pions decay in flight - goes to
+						a matching section, before going to the transport section with
+						a 3 T field. A prototype of this system has been built and operated
+						successfully at Osaka University.

+						Negative muons  are selected by a dipole field, which 
+						is created by an additional winding on top of the solenoid
+						windings. A collimator is placed in front of the detector section
+						to eliminate high momentum muons (and survival pions).

+						There will be two detectors for two goals of COMET Phase-I: physics
+						measurements and background measurements. 
+						
+						Detector for background measurements consists of a solenoid magnet,
+						0.8 - 1 T, 5 straw tube tracker layers and a crystal calorimeter.
+							This is regarded as a final prototype for Phase-II detector.
+						A lot of detector R\&D  activities are ongoing: ECAL
+						with GSO/LYSO crystals and APD readout; prototype of straw tube
+						tracker; front end electronic board.

 							\label{fig:phys_det}
 						\end{figure}
+						There are two options for the detector for $\mu-e$
+						conversion search. Baseline detector is a cylindrical drift chamber
+						(CDC), shown in the detector section in Fig.
+						\ref{fig:phase1}. The CDC would help reducing background rate and
+						hit rate. The other option is a transverse tracker, in
+						which the detector for background measurements will be reused.
+
+						The CDC is placed inside a magnetic field of 1 - 1.5 T. The
+						magnetic field and radial size of the CDC are adjusted to accept
+						particles with momentum larger than 70 MeV/c. Segmented triger
+						hodoscope is located before the drift chamber, provides timing
+						signal and reduces protons hit rate on the chamber. In order to
+						reach the goal SES, energy resolution requirement for the CDC is
+						1.5 MeV at 105 MeV.

-				%    As you can see it is possible to make your poster very colorfull. But in 
-				%    most cases this will this will overload your poster. If you don't change 
-				%    the color settings you will get the default look, which consits of some
-				%    shades of the jacobs blue and some decent green highlights. These colors 
-				%    where chosen carefully to keep a consistent look of the poster. The 
-				%    \emph{cpbgposter} style is installed our office computers, so you should be
-				%    able to compile this example out of the box with pdflatex. If you want to
-				%    work on your computer make sure that you have a recent TeX distribution 
-				%    (TeXlive 2008, Miktex) and download the beamerthemecpbgposter.sty file from
-				%    our teamwork page and put it in your local TeX directory.
-				%
-				%    If you have any questions, critics, ideas or if you just want to praise the
-				%    awesome dude who created this insanely great poster style then don't
-				%    hastitate to write an email to \emph{j.liebers@jacobs-university.de}
