Abstract :
The high intensity pulsed electron beam of KALI-5000 system is used to develop a flash x-ray source. The KALI-5000 system is capable of generating intense relativistic electron beam (IREB) of 1 MeV, 60 kA and 100 ns when connected to impedance matched electron beam diode. This system is operated in 6 GW, 100 ns duration to produce the bremsstrahlung flash x-ray on a tantalum target of planner anode-cathode geometry. The axial and the radial dose distribution are characterized using CaSO4: Dy TLDs (thermoluminescent dosimeter) as well as using the optical densitometer to measure the dose distribution of the exposed x-ray film. The measured dose distribution by TLDs and the optical densitometer plus x-ray film matches within ± 5%.
