激光离子源是重离子源中的一种候选源。利用漂移速度Nd：钇铝石榴石激光器产生的高密度等离子体实现了大电流、高电荷态离子束。为了获得更高的束流，我们在LIS上进行了实验，通过磁场的约束效应可以获得更高的束流。用法拉第杯测量总电流，用静电离子分析仪分析电荷分布。结果表明，永磁体可提高离子束的荷电状态。
Laser ion source (LIS) is a candidate among various heavy ion sources. A high density plasma produced by Nd:yttrium aluminum garnet laser with drift velocity realizes high current and high charge state ion beams. In order to obtain higher beam current, we made experiments using the LIS with a magnetic field by which a confinement effect can make higher beam current. We measured total current by Faraday cup and analyzed charge distribution by electrostatic ion analyzer. It is shown that the ion beam charge state is higher by a permanent magnet.
