Embodiment 1

[0042] 1. The specific method of adjusting the front and rear positions of the coupling ring. By manually rotating the forward and reverse of the adjustment knob, the threaded telescopic rod drives the coupling coil to move forward and backward. At the same time, use a network analyzer to test the transmission power. When the transmission power is greater than 88.9%, it is considered that most of the power has been fed in, and it is acceptable. Within the range, and take the position of the coupling coil at this time as the final fixed position.

[0043] 2. The method of adjusting the capacitor plate. Set the front and rear positions of the capacitor plate by manually controlling the adjustment knob, and use a network analyzer to measure the frequency during the movement. First, measure the frequency parameters of the helical resonator at the maximum stroke and the minimum stroke, so as to determine the spiral resonance of the capacitance fine-tuning plate According to the ad...

Abstract

The invention discloses a DC beam cutting device based on sine wave waveforms. The cutting device comprises a spiral resonator and a beam cutting pole plate device. The spiral resonator is used for providing a high-frequency voltage for the beam cutting pole plate device, and the beam cutting pole plate device is used for providing an alternating electric field for beam passing and beam deflecting. The spiral resonator comprises a capacitance fine-tuning pole plate used for accurately fixing the inherent frequency of the spiral resonator, a coupling coil adjusting bracket used for adjusting the resonant frequency of a coupling coil, and a solenoid coil supporting framework used for keeping the distance between coils constant and keeping the diameter of each turn of coil unchanged. According to the invention, the technical problem that the high-precision inherent frequency of the resonator cannot be realized for a long time in the field is solved. The capacitance fine-tuning pole plate,the coupling coil adjusting bracket and the solenoid coil supporting framework are organically combined, supported by one another and dependent of one another, so that the difficulty that the high-precision inherent frequency cannot be realized only by solving problems from one aspect is solved.

Description

technical field [0001] The invention belongs to the field of accelerators, in particular to a DC beam cutting device based on a sine wave waveform. Background technique [0002] In the field of accelerator technology, the temporal structure of the beam is generally determined by different types of accelerators. For example, a continuous DC beam accelerated by a high-voltage accelerator will still be a continuous DC beam, while a continuous DC beam will be a quasi-continuous beam with a very high frequency after being accelerated by a cyclotron. In some specific experiments such as nuclear data measurement, neutron physics experiment and material property research, pulse beams with specific time structure and repetition frequency are required. To obtain a beam with a specific repetition rate and a specific pulse width, it is necessary to pulse the injected DC beam and then accelerate it through an accelerator. In the DC beam pulse system, the continuous DC beam can be forme...
