This phase has a main program and a timer interrupt routine that runs every two microseconds.
The dynamics of the channel takes place on the microsecond time scale, so the channel is static during the passage of a beam ion.
At very high beam intensity it is of order of a few microseconds.
The camera shutter speed was adjusted so that only one flash occurred while the shutter remained open; the duration of illumination was about 2 microseconds.
The extraction voltage was so optimized to obtain the current profiles having approximately the flattop region after the initial peak for several microseconds.
It is a slow process, and cannot generate an equivalent quantity of fog to that in the few microseconds of a water arc explosion.
Dense matter from such wire explosions persists for microseconds and droplets eventually form.
The software is run while receiving echoes and processes all eight channels within 150 instruction cycles or two microseconds.
