Fig. 5.5 - Maps of some relevant quantities at the time ts corresponding to the vacuum closure aftera a flight<br />

of 75 µm. (Te the electronic temperature, kin the ionic kinetic energy associated to the flow, U z the velocity<br />

along the z axis).<br />

three foil target. The<br />

focusing conditions on<br />

the first layer from the<br />

right the same as in case<br />

3 of table 5.I. It is shown<br />

the map of the velocity<br />

along z when the first<br />

foil collides with the<br />

second (at t=0.65 ns).<br />

Typical negative velocity<br />

is about 2 (in units of 10 7<br />

cm/s).
