Design and development of pulsed electron beam accelerator'AMBICA – 600'

Pulsed Electron-Beam Heating

A pulsed, 20 kv electron beam is focussed upon a vapor-deposited thermocouple, and the resulting temperature vs. time response is studied. The experimental data show much scatter, but are consistent with the theoretical prediction that the characteristic thermal response time T is proportional to d , where d is the beam diameter at the thermocouple. From these data, for the soft-glass substrate...

Pulsed Electron Beam Annealing of Arsenic-implantation Damage in Silicon

A SPIRE-300 pulsed electron beam processor has been used t o recrystallize (100) and (111) 15 Si wafers implanted with As (140 keV 10 cm-2). The machine parameters have been selected t o obtain an electron energy deposition profik convenient for melting of the silicon surface 2 down t o 1 J/cm . The best regrawth layer quality and As incorporation wereobtained with electron energy densities in ...

Measurements of Photon Beam Flattening Filter Using an Anisotropic Analytical Algorithm and Electron Beam Employing Electron Monte Carlo

  Introduction: This study aimed to report the measurement of photon and electron beams to configure the Analytical Anisotropic Algorithm and Electron Monte Carlo used in clinical treatment. Material and Methods: All measurements were performed in a large water phantom using a 3-dimensional scanning system (PTW, Germany). ...

Design of Electron Beam Sludge Hygienization Plant

The laboratory scale studies had been carried out regarding the possibility of electron beam application for sludge hygienization. Experimental system with nozzle type sludge feeder and stainless steel belt conveyor was constructed for irradiation under continuous feeding conditions of sludge cakes with electron beam of dose rate of 40kGy/s. Survival curves of microbial population for total col...
