Abstract :
The potential of using the active iodine inlet control technique for improving the COIL near field intensity uniformity is examined for the first time. The output intensity is detected by an intensity sensor such as an infrared charge coupled device. The detected information is feedback to control the inlet pressure of iodine orifices on the supersonic nozzle. Computer simulation result proved the validity of the proposed method. Filled factor of the near field intensity updated from 0.4 to 0.46 after active iodine inlet control system is applied. The result suggests a effective approach to improve the COIL near field output intensity uniformity.
