随着亮度的增加，需要拦截光束的光束诊断技术变得不切实际。对于H粒子束，基于光解离现象的解决方案目前正在洛斯阿拉莫斯国家实验室加速器测试台（ATS）进行调查。可以使用激光器来选择性地中和可以在带电粒子已经被扫走之后表征的射束的部分。我们已经使用这种技术的测量电流密度与纵向相位和纵向相位空间分布在输出的ATS射频四极杆（FDG）。我们的测量结果进行比较的粒子动力学代码，PARMIEQ的预测。
With increasing brightness, beam diagnostic techniques requiring interception of the beam become impractical. For H- particle beams, solutions for this problem based on the phenomenon of photodissociation are currently under investigation at the Los Alamos National laboratory accelerator test stand (ATS). A laser can be used to selectively neutralize portions of the beam that can be characterized after the charged particles have been swept away. We have used this technique for the measurement of current density versus longitudinal phase and the longitudinal phasespace distribution at the output of the ATS radiofrequency quadrupole (RFQ). The results of our measurement are compared with the predictions of the particle-dynamics code, PARMIEQ.
