Trigger system for industrial CT

In the industrial computed tomography system, a 6 Mev X ray accelerator, detector, electronic system and computer system is included. The electronic system include front-end amplifier, ADC, DAQ and trigger system All the railway motors, accelerator, front-end circuit, ADC, DAQ is working by the commander of trigger system. This paper illustrates the total trigger system, include the absolute encoder interface (parallel type or serial type encoder), trigger pulse interface, slow control interface with Ethernet and CCM interface to the DAQ system.
