	Funding: This research is supported by U.S. DoE Two conceptual designs of multi-beam klystrons with parameters suitable for ILC and for the 8-GeV pulsed stage of Project X (PX) have been developed. The chief distinction of these tubes from other MBKs is their low operating voltage, namely 60 kV for the ILC tube and 30 kV for the PX tube. Advantages of low voltage include no requirement for pulse transformers or oil-tanks for high-voltage components, and compact modulators. A 6-beamlet quadrant of the ILC tube has been built and is undergoing tests; it is designed to produce 2.5 MW at 1.3 GHz in a 1.6 ms wide pulse at a 10 Hz pulse rate; a four-quadrant future version would produce 10 MW. The 6-beamlet PX tube is to produce 520kW, and would operate in one of two regimes, either at a repetition rate of 2Hz delivering 30 msec pulses, or at a repetition rate of 10Hz delivering 8.5 msec-long pulses. The PX tube is currently undergoing engineering design, with construction scheduled for completion towards the end of 2014.
