The Research Of Neutron Generator Console Automation

Neutron tube of generator neutron is the most popular neutron source technology, due to its low prices, miniaturization, it has become one of the popular neutron source among the application. Traditional neutron generator console use mechanical potentiometers to control, the boot process needs an experienced laboratory to adjust, and during normal operation, also need to adjust to make the neutron yields stable. In view of this situation, neutron generator is improved; automation control will make its use more convenient, security and reliability.In this paper, we will introduce the structure of the neutron generator and traditional console, then analysis the process of adjustment to put forward specific improvement scheme. In the hardware circuit, because the neutron generator will be affected by various influences, need continuously adjust various parameters. In order to make the neutron yields stable, we use the closed-loop control. The ion source current that influences the neutron yields is got by the signal isolation and independent suspension power. And use digital potentiometer to realize digital signal control simulation. And through the change of ion source current to change the adjustment speed, reduce the vibration, reach steady state quickly. Another exception handling can reduce risk and loss, when the accident happens such as discharge.In short, this paper based on the automatic control system of Sunplus microcontroller; simulate the process of manual adjustment, so that whole system operation is more convenient, safe and stable.
