DESIGN AND CONSTRUCTION OF A DIAGNOSTIC PULSED X-RAY TUBE

A pulsed X-ray Tube based on the field emission cold cathode principle has been designed and constructed. The device produced X- ray pulses of duration of (1.2) μ sec and intensities of (90) mR at a distance of (10) cm from the window, when a (150) KV is discharged across the electrodes of the tube. The intensity of the x ray radiation at various distances was determined at various cathode anode spacing to determine its optimum value. Special efforts were made in the design to be demountable, easy to maintain, and offering a practical possibility for future industrial and medical application.
