Relativistic electron beam generation studies have been carried out in LIA-400 system through explosive electron emission for various cathode materials. This paper presents the emission properties of different cathode materials at peak diode voltages varying from 10 to 220 kV and at peak current levels from 0.5 to 2.2 kA in a single pulse duration of 160-180 ns. The cathode materials used are graphite, stainless steel, and red polymer velvet. The perveance data calculated from experimental waveforms are compared with 1-D Child Langmuir formula to obtain the cathode plasma expansion velocity for various cathode materials. Various diode parameters are subject to shot to shot variation analysis. Velvet cathode proves to be the best electron emitter because of its lower plasma expansion velocity and least shot to shot variability.Index Terms-Electron beam applications, electron beams, electron emission, electron sources, plasma devices, pulse power systems.

“…These systems have been used for basic studies of relativistic electron beam (REB) generation, plasma expansion velocities, diode perveance, vircators for microwave generation and flash X-rays. These intense REB produced so far are in the range of applied diode voltage 250-450 kV for planar and cylindrical diodes [9][10][11]. Basic studies gave the confidence to built a 30 GW pulsed accelerator and KALI-5000 has been dismantled to give way for KALI-30 GW system in the same enclosure by changing inner circuit completely enabling more energy efficient and compressed output (80 ns).…”

The design, development and commissioning of 1 MV pulsed electron accelerator producing Flash X-Rays is described in this paper. This pulsed power system is based on bipolar MARX generator and Blumlein followed by Explosive electron emission diode assembly. The peak pulsed power is ∼ 30 GW. The electron energies in the range of 400 keV to 1030 keV are produced and delivered to experimental load of Industrial diode. Electrons are emitted from a stainless steel ring at ground potential by explosive field emission and bombard the anode tungsten pin for flash X-rays generation. The relativistic electron beam has been simulated within the diode chamber and pattern shows the beam propagation. Imaging plates are used to characterize the source size and optimization has been reported.

“…As the peak power that has to be delivered to the induction cavity is huge, it cannot be handled easily with semiconductor devices. This difficulty can be overcome by operating the solid state modulator for long duration pulse generation and subsequently compressing the pulse using four magnetic compression stages [1].…”
