Available in PDF, EPUB and Kindle. Book excerpt: It is shown that the fields generated by relativistic electron (positron) bunches moving in overdense cold plasma have two components -- wake and Coulomb. The existence of the Coulomb component is caused by the absence of the Debay screening of the charge moving in plasma with the velocity greater than the thermal velocity of the plasma electrons. It is shown that at some conditions the contribution of the Coulomb component to focusing and self-focusing of the electron (positron) bunches, and wake field generation could be essential. This conclusion is valid for different descriptions of cold plasma-relativistic electron bunch system.
