摘要： This invention relates to a pulse generator circuit for delivering a short high current pulse to a load. This pulse generator comprises a junction recovery diode, a switch, a first resonant circuit and a second resonant circuit. The diode may be configured to store charges in its depletion layer when there is a forward flow of a current and to rapidly switch open after the depletion layer is discharged by a reverse flow of a current. After the diode rapidly switch opens, the pulse generator may provide a reverse current to the load. This pulse generator may be configured to generate at least one pulse that is having a length of no more than 100 nanoseconds at the full-width-at-half-maximum and an amplitude of at least 1 kilovolt. Electrodes may be connected to the pulse generator to deliver one pulse or plurality of pulses to biological cells such as tumor cells.

摘要： A transient plasma electrode apparatus may include an elongated electrode having a first and a second end. The first end may connect to a source of high voltage pulses. An insulation jacket may surround a portion of the electrode. An electric-field enhancing protrusion may be at the second end of the elongated electrode. The protrusion may cause an electric field when a high voltage is applied between the elongated electrode and a metallic wall of a combustion chamber in which the electrode is placed. The electric field may be greater at the second end as compared to along the length of the electrode.
