1. A plasma-generating device, comprising:
a plasma chamber;
an anode;
a cathode having a tapering tip, the tapering tip having a first portion disposed proximal to the plasma chamber and a second portion extending into the plasma chamber and terminating proximal of the anode, the anode and the cathode configured to establish an electric arc with a current of about 4-10 A to generate plasma having a temperature of at least 10,000° C.;
a plasma outlet configured to discharge the plasma as a charged plasma jet out of the plasma-generating device at a temperature of at least 10,000° C.; and
a coolant channel configured to receive a coolant such that the coolant flowing through the coolant channel cools a portion of the plasma-generating device adjacent to the cooling channel.
