In order to collect XAS data using the 7-element detector through either the webXAS or xmapGUI programs, the Linux computer (s043lx1) must first connect to the Xspress3 detector electronics server and start the EPICS IOC there.


  • Open a Terminal window on the Linux Machine.  In the upper left hand corner pull down menu, select System Tools → Terminal
  • In the terminal window, type  
    • ssh -Y xspress3@192.168.43.7
  • At the password prompt, type
    • x5pr3553
  • Once logged into the server, type the following command: 
    • screen 
    • xspress3-ioc.sh
  • To exit the screen shell session, type "Ctrl+a" and then "Ctrl+d". 
    • WARNING: pressing Ctrl, a, and d buttons all together does NOT work and will STOP the xspress3 IOC!!

  • Type

    • logout
  • Close the terminal window


At this point, you should be able to run either the web Ge program inside webXAS, or run xmapGUI, and see spectra.  If that does not work, close all Firefox windows or xmapGUI application windows, following the instructions to Restart ICS and reopen the application.
