VARIPULSE X-RAY SYSTEM. A BIOLOGICAL X-RAY SYSTEM FOR USE IN ULTRAFRACTIONATED DOSE STUDIES
The equipment and operation of the Varipulse X-ray System are described. The system is designed specifically for ultrafractionated dose studies. The heart of the system is an x-ray triode tube which permits rapid on- off switching of the output. The bulk of the system comprises equipment for supplying the required high voltage and pulsed control voltages necessary to the operation of the triode. The output of the system is in pulses continuously variable in length from less than one microsecond to greater than one millisecond with the duty cycle independently and continuously variable to values greater than 50%. The x-ray triode may be operated at anode voltages up to 100 kv d-c at pulse currents up to 100 ma and average currents up to 5 ma. Thus, an extreme range of the critical vsriables, pulse length, and on to off time ratio, is available at useful x-ray levels for studies of the biological effects of ultrafractiorated x- ray dose.
