Channel formation experiments have been conducted with a small Prototype machine. This machine is a 600 kV, 5 60 ns water transmission line charged with a Marx generator. With fill pressures of 1 to 4 atmospheres, these experiments have created channels of 0.1 mm radius at currents up to 100 kA. The density distribution of a channel is measured by a Moire-Schlieren technique with illumination by a short pulse N2 laser (3373 A). An example of such a channel photograph is shown in Fig. 20. In these experiments no sausage or kink instabilities have been observed out to 120 ns. 

A Gaussian pulse with t = 6 fs (a measured FWHM of 10 fs, the order of magnitude of the shortest pulses that can be generated by current Ti sapphire lasers) includes a span of about 6.25 x 10 Hz, which corresponds to an energy hv) band of 2.0 X 10 cm If the spectrum is centered at 800 nm (12,500 cm ), its FWHM is 274 nm. Figure 3.12 shows the energy distribution function for such a pulse and for pulses with FWHM s of 20 and 50 fs.
