Assymetric, what makes the x-ray data so striking is that it can’t come from the beam hitting the anode. There is 4 inches of lead between the point where the beam hits the anode and the NTF or the FTF. Either the first x-ray peak comes from beam elctrons that are trapped in the plasmoid or from the heated electrons in the plasmoid itself. I’m still analysing the last several months’ data on this. the second x-ray peak, which is also pretty hot, comes well after the beam.
