Description

The laser ion source (LIS) features a compact design, straightforward operation, and ease of maintenance. In this work, an inner-assembled solenoid is employed to confine the ion beam, thereby mitigating plasma expansion and reducing ion loss. The influence of laser power density on peak current, pulse width (FWHM) and total charge of Al, Cu, Fe and Ni ion beams in the range of 350 mJ-1450mJ is studied. The results indicate that increasing laser power enhances the peak current and ion energy, with Ni exhibiting a pronounced threshold behavior. With the application of an inner-assembled solenoid, the beam intensity of different ions at 540 mm and 900 mm increased by 2 to 5 times. The peak currents for Al, Fe, Cu, and Ni are 167 mA, 113.9 mA, 108.4 mA, and 111.5 mA, respectively, accompanied by prolonged pulse durations and enhanced total charge. Velocity distribution analysis confirms that the magnetically confined plasma still adheres to a Maxwellian distribution.
