Beam injection systems in hadron colliders require kickers generating ±50 kV peak voltages into a 50 Ω impedance, with peak currents of 1000 A and sub-10 ns rise and fall times. This paper presents a novel high-voltage pulse power generator utilizing a dis-tributed pulser architecture. It combines gallium nitride (GaN) transistors in a Marx to-pology with an inductive adder, achieving nanosecond-scale switching speeds and high-power efficiency. Compared to other solutions such as based on MOSFETs or fast ioniza-tion dynistors, our development offers superior peak and average power performance, reduced system complexity, and enhanced reliability, marking a significant step forward in high-voltage pulse generation for accelerator applications.

X-ray generators, producing radiation in the MeV range, are a critical tool for radiography, non-destructive testing, and security applications. The field operation of such source requires them to be hand-portable, autonomous, and allow parameter adjustability. The dramatic level of miniaturization and cost-reduction of electron linac is achieved thanks to the implementation of such innovative technologies as air-cooled Ku-band air-traffic control magnetrons, split accelerating structure fabrication technique, and solid-state Marx modulators. In this talk, we present the design and test results of a 2 MeV Ku-band electron linac for a hand-portable X-ray generator system for field radiography, being developed by RadiaBeam.
