One GW - S-Band Relativistic Klystron Amplifier

MDS is developing a 1.5 GW relativistic klystron amplifier operating at 3.5 GHz with 60% efficiency at a minimum pulse width of 1 microsecond which yields 1.5 kilojoules of energy per pulse. The pulse repetition frequency is 500 Hz giving an average RF output power of 750 kW. We will employ an electron gun with a thermionic cathode operating at 1.1 megavolts with a beam current of 2300 A. The RF wave-electron interaction circuit consists of a four cavity bunching circuit with a high efficiency four cavity extended interaction circuit. The klystron will exhibit long life and with a all-brazed ruggedize construction, will be field deployable. We offer this RF pulse power source for high power radar, long-range electronic warfare, directed energy, future high gradient particle colliders, and for high gradient accelerators for industrial and medical use.
