提出了一种研究离子束中微粒子受力的新实验。宽束离子源提供垂直向上定向的束，其中注入100微米的中空玻璃球。粒子被二极管激光照射，并用电荷耦合器件相机记录。根据轨迹，确定加速度和颗粒上的净力。获得了静电方法无法获得的高能中性原子的信息。
A novel experiment for the study of forces on microparticles in ion beams is presented. A broad beam ion source provides a vertically upward directed beam wherein 100 microm hollow glass spheres are injected. The particles are illuminated by a diode laser and recorded with a charge-coupled device camera. From the trajectories the acceleration and the net force on the particles are determined. Information on energetic neutral atoms is achieved, which is not accessible by electrostatic methods.
