研究目的
Investigating the control of ion current waveform in a laser ion source using pulsed magnetic fields to produce an ion beam with a flat-top-shaped pulse.
研究成果
The application of a pulsed magnetic field to a laser-produced plasma is an effective method to control the ion current waveform, enabling the production of an ion beam with a flat-top-shaped pulse. This method can maintain the ion current waveform peak for approximately 50 μs.
研究不足
The study was limited to the investigation of plasma behavior under specific conditions of static and pulsed magnetic fields. The applicability of the findings to other conditions or types of plasmas was not explored.
1：Experimental Design and Method Selection:
The study used a solenoid-generated static and pulsed magnetic field to investigate plasma behavior and control the ion current waveform.
2：Sample Selection and Data Sources:
A copper plate was used as the laser target to generate plasma.
3：List of Experimental Equipment and Materials:
An Nd:YAG laser, a Faraday cup, a solenoid for generating magnetic fields, and a digital delay/pulse generator were used.
4：Experimental Procedures and Operational Workflow:
The laser was used to generate plasma from the copper target, and the ion current was measured with a Faraday cup. The effect of static and pulsed magnetic fields on the ion current waveform was investigated.
5：Data Analysis Methods:
The time evolution of the transverse ion current profile was analyzed to understand the effect of magnetic fields on plasma behavior.
