Several subsystems of the machine have been carefully designed and tested to prepare for x-ray generation. To maintain proper operation of the machine, pulse signals are generated to synchronize various subsystems. The timing system, based on the previous version designed on Xilinx Spartan-3 FPGA, is upgraded with better timing resolution, easier configuration with more timing channels, and future expansion of the system. A new LabVIEW GUI is also designed with more details on timing parameters for easy customization. The result of this new design is satisfactorily achieved with the resolution of 10 nanoseconds per time step and up to 15 synchronized timing channels implemented on two FPGA modules.}, }
