A prototype of 6 MeV medical linear accelerator has been under development at Synchrotron Light Research Institute (SLRI). 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.

The prototype of industrial linac for food irradiation application using x-ray has been under development at Synchrotron Light Research Institute (SLRI). Several subsystems of the machine are carefully designed for proper operation. Material handling system with its motion control and its relationship with a beam scanning system is explained in this paper. Hardware selection and software development together with a networked control system is described. This system is being developed and tested with the object detection system to monitor and control the position and velocity of materials on a conveyor belt.

The prototype of linear accelerator for industrial applications has been under development at Synchrotron Light Research Institute (SLRI). The primary purpose of this new project is for food irradiation application using x-ray. For efficient beam scanning purpose, a real-time object detection system has been developed by using a machine vision USB camera. The software has been developed by using OpenCV which is run on an embedded system platform. The result of the image analysis algorithm is used to control a beam scanning magnet system of the linac in real-time. The embedded system, both hardware selection and software design, running the object detection task will be described in this paper.
