| Abstract: | Based on the Double Grid Air Counter(DGDC)of the smart sensor system,this paper studies the process of the air counter,which reachs working time sequence,range and width algorithm of the quenching voltage are proposed,and prohibitive voltage,and then designs control circuits based on quenching circuit and prohibitive circuit.Experimental results show that the double grid air counter and its control circuit can be used to control the discharge volume and secondary electron emission,which can count effectively. |
