Sketch of experimental arrangement. The lightpipe allows signals to be recorded electronically in a well-shielded location about from target chamber center.
Streak data for scintillator/neutron pulse. The optical streak image (center) shows the fidu timing pulse train at the top and the scintillator pulse below. Lineouts on a nanosecond time scale for the fidu and scintillator are shown on the top and bottom, respectively.
Streak data for neutron Cherenkov/neutron pulse. The window optical streak of the fidu and neutron signals are shown with the same layout as in Fig. 2. Here, the FWHM represents a convolution of the fusion burn width and the streak camera resolution.
Digitizer recording of threshold Cherenkov -ray signal. The digitizer recording shows that the distinct Cherenkov signal at (solid) precedes the neutron Cherenkov signal by about . With the removed from the detector cell, only the neutron Cherenkov signal (dashed) remains.
Relative timing of neutron and threshold Cherenkov signals. Identification of the threshold Cherenkov -ray signal is confirmed by temporal correlation with the neutron signal (shown above) and by amplitude correlation with neutron yield.
