A transmission path (line) may extend between the pulse and microwave generators and circuit elements of the impedance network (circuit) connected directly and/or via a switch between transmission path and ground. A capacitor 211, 213 may be switched across the network in series, parallel or short circuited or combinations of any, by means of the capacitor selection switch S 212. The transmission path may include a pulse transformer 206 or inductive adder. The switchable impedance network (e.g switched capacitors) may form many series and parallel configurations (figures 4-8) and may be selected by a relay switch and/or one or more semiconductor switches (e.g FET, IGBT). The network impedance may thus be controlled in response to sensed or anticipated variations in the magnetic field strength generated by an electromagnet or permanent magnet in the microwave generator, the power in the microwave generator further controlled by the magnetic field strength. The microwave generator may generate first and second output power microwaves in response to receiving pulses of electrical power having first and second input power, the first/second output power used to drive an electron accelerator (101 figure 1) to accelerate electrons of variable power suitable for a medical imaging x-ray generator (107,111,113).
