 ===== CEPC detector studies =====
+**People:** S.Chekanov, M.Demarteau
 This wiki explains how to view electron-proton collision events for CEPC.
 To analyse events for such studies, install [[http://atlaswww.hep.anl.gov/asc/jas4pp/|Jas4pp]] program (assumes "bash"):

+====== Wired Visualization ======
+You can run Jas+Wired to visualize the simulated events.  The Wired program is included in the Jas4pp program. Run it as:
+<code bash>
+jaspp sifcch1.heprep
+</code>
+You can download the heprep file from [[http://atlaswww.hep.anl.gov/hepsim/soft/detectors/sifcch1/sifcch1.heprep]];
+Alternatively, visualize the detector as **[File]-[Open data source]-[HepRep]** XML.
+You will see the detector layout.
+Now, we will read the event: Open any *.slcio file you copied from HepSim as
+**[File]-[Open data source]-[LCIO]** file.  Then click a small button [Go] (top menu bar). It will process
+ events.  Then select again **[File]-[New]-[Wired 4 view]**.  You will get an image in the Wired4 display as this:
+{{:fcs:event.png?400|}}
+Now press [Go] again to look at next event.
+If you want to see how data records are organized inside the slcio file,
+do this **[File]-[New]-[LCSim Event browser]**
+To view "slcio" files, Jas4pp automatically downloads the detector  geometry from [[http://atlaswww.hep.anl.gov/hepsim/soft/detectors/]], therefore, you do not need manual download of heprep files.
