| Abstract: | The former counter designed based on the theory of eddy of the 10MW HTR fuel-handling system was optimized to improve the system's capabilities.The constant-current-source stimuli generator was adopted instead of the former constant-voltage-source,and the amplitude and frequency of the stimuli source were changed to be adjusted.The experimental results indicated that through these optimizations the counter could fit for the complexity of the field,increase the sensitivity of the sensor,and improve the reliability of the system. |
