neutron tube

By using C8051F040 SCM to control the neutron tube ′ s filament voltage, the target voltage and the pulse of the anode, the downhole tool can work at an ideal state.

通过C8051F040单片机对中子管的灯丝电压、靶压以及阳极脉冲进行控制，使其工作在一个理想状态，是提高仪器测井效率、延长中子管使用寿命的重要手段。

A sealed tube neutron generator with neutron yield more than 1.5 × 1010/ s has been developed. Consisting of a demountable neutron tube, a high voltage source and a control unit, this device has been used in neutron radiography.
