- | This wiki explains how to view electron-proton collision events. The analysis package is described in | ||
- | [[https:// | ||
- | |||
- | |||
- | We will use e-p events shown in [[http:// | ||
- | The full simulation files are located under the tag " | ||
- | |||
- | ====== Visualizing events with Jas ====== | ||
- | |||
- | First, install [[https:// | ||
- | Then copy the detector geometry file to the local directory where the file " | ||
- | <code bash> | ||
- | wget http:// | ||
- | </ | ||
- | This creates a directory " | ||
- | in [[http:// | ||
- | |||
- | Now we can visualize the detector as **[File]-[Open data source]-[HepRep]** XML and select file " | ||
- | This is how to do this using the command line: | ||
- | |||
- | <code bash> | ||
- | ./fjas sidloi3/ | ||
- | </ | ||
- | Now you should see the detector layout. | ||
- | |||
- | Next, we will read the simulated events: Open any *.slcio file you copied from HepSim using the menu | ||
- | **[File]-[Open data source]-[LCIO]** | ||
- | For e-p events, use this LCIO file from [[http:// | ||
- | |||
- | <code bash> | ||
- | wget http:// | ||
- | </ | ||
- | |||
- | |||
- | |||
- | Then click a small button [Go] (top menu bar). It will process | ||
- | | ||
- | do this **[File]-[New]-[LCSim Event browser]** | ||

- | Here are images of ep collision with a scattered electron identified using the PFA. | ||
- | The images were done using DIS ep samples [[http:// | ||
- | Reconstructed electron energy from PFA: E=16.92 GeV | ||
