Rogowski coils have been used for decades for non-invasive current measurement when other probe, such as current shunts, current transformers are impracticable. The measurement of diode beam current in pulse power system under vacuum and high voltage are challenging task which requires development of Rogowski coil for specific applications. They operate in large radiation fields, under intense electron...
This paper is intended to report design methodology and implementation experiments of solid state based triggering arrangement for MARX generator of KALI-5000 (1MV, 40kA, 100nS) pulsed power system. The 15 stage bipolar MARX generator of KALI-5000 system is triggered using three triggered sparkgaps. An IGBT based trigger supply is used to trigger the first spark gap and consecutive two sparkgaps are...
In recent years, pulsed power systems have gained importance for the pulsed electron beam generation for industrial and defense applications. High voltage Energy storage capacitors were being used widely worldwide for the pulsed power system in electric field. In case of capacitive energy storage system, the size of the system is decided by capacitor size which depends on dielectric strength and relative...
This paper presents the experimental results of a repetitive Marx generator being developed at BARC. Effect of lead inductance, sparkgaps' alignment, charging inductor, ground inductor and shielding has been studied. Two types of configurations have been adopted in order to reduce the erected Marx inductance and results are compared. In this Marx generator plus-minus charging scheme was adopted for...
A pulse power system (1 MV, 5 0kA, and 100 ns) based on dual polarity charged Marx generator and Blumlein pulse forming line (PFL) was built to generate high power microwaves. This paper describes the inherent prepulse present with the Blumlein configuration and the mitigation strategies adopted. Further, a qualitative attempt to verify the generation of high power microwave output on the system is...
