Figure 8

Velocity distribution in the target jet. The velocity distribution is determined from the time-of-flight distribution of helium excited by electrons with threshold energy, and the logistic fit to the experimental data is used in simulations of the experiment. The mean velocity is 1624 ms −1 and the full width at half maximum (FWHM) of the distribution is 220 ms −1.
