Embodiment Construction

[0050] Below in conjunction with accompanying drawing, the present invention is further explained:

[0051] Design principle of the present invention

[0052] 1. The design principle of low-power continuous exercise mode: what needs to be crossed in the initial stage of accelerator cavity exercise is the multi-point effect area with relatively low voltage. If you cannot cross this multi-electron area with relatively low voltage, you will not be able to increase the power if you increase the power. . Since the low power is applied to the accelerator cavity in the low power stage, the reflection caused by the multi-electron effect is small and will not cause damage to the equipment, so the continuous wave emission method can be used in the low power stage.

[0053] 2. The design principle of the medium-power pulse exercise mode: After crossing the low-power stage and producing several regions that produce multiple electronic effects, it is necessary to use a higher-intensity me...

Abstract

The invention discloses a cyclotron low-level system restart automatic exercise device. The device comprises a cavity sampling signal unit, a detector unit, an ADC sampling unit, an FFT conversion anddata return-to-zero and data processing unit, a comparison unit, a control output signal unit, a cavity sparking detection unit, a cavity sampling signal processing unit and a motor control unit. Theautomatic exercise device obtains a sampling signal from an accelerator cavity, processes the sampling signal, and outputs the signal to a transmitter and a motor controller. The invention further comprises an intelligent control method. The intelligent control method comprises the steps of setting threshold parameters in different modes; entering into a low-power automatic continuous exercise mode; entering into a medium-power automatic pulse exercise mode; and entering into a medium-power automatic continuous exercise mode. In the invention, all automation of a cyclotron restart exercise stage is achieved, complex processes which need manual judgment in a cyclotron operation process are effectively simplified, and operation efficiency in a low-level operation process is improved.

Description

technical field [0001] The invention relates to the technical field of a cyclotron, in particular to an automatic exercise device and a control method for restarting a low-level system of a cyclotron. Background technique [0002] Cyclotrons are widely used in basic research on atomic nuclei, nuclear engineering, chemistry, radiobiology, radiation medicine, and solid-state physics, as well as disease diagnosis and treatment, activation analysis of high-purity substances, radiation treatment of certain industrial products, agricultural products and others Radiation processing of food, simulation of cosmic radiation and simulation of nuclear explosions and other fields. [0003] When we need to make a commercial cyclotron and deliver it to customers, during the early processing, transportation, other long-term contact with the atmosphere, or after the cyclotron has been shut down for a long time, the cyclotron cavity (the The inner surface of the cavity (the device for establ...
