Quit on moving electron detector in, because a limit switch stops us a 0mm.  
Alex hints theres a way to overcome this, but we don't know what it is...maybe 
he can help later with that.
Run #20159, 20160 are "negative" electron detector positions, but compton edge 
in these runs is seen at same place as 20158 (0mm edet position).
