Abstract :
Summary form only given. 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 1MeV, 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 plusmn5%.
