起源于阿贡国家实验室的非破坏性光束探测器系统允许在加速和瞄准周期中连续测量零梯度同步加速器（ZGS）中的质子束位置和光束轮廓。无损检测是通过收集真空室中质子束电离残余气体产生的离子来完成的。通过将这些离子收集到不同的电极上而获得的电流振幅取决于光束中质子的分布。电信号的特性使它们适合作为计算机系统的输入。模拟和数字技术已经被用来确定光束的位置和轮廓。这些光束检测系统已被用于测量喷射器直线加速器和同步加速器环之间的50 MeV光束的特性；研究了加速过程中梁的转向和径向尺寸的增长；在靶向序列中进行测量。
The nondestructive beam detector systems originated at Argonne National Laboratory allow continuous measurement of the proton beam position and beam profile in the Zero Gradient Synchrotron (ZGS) during the accelerating and targeting cycle. Nondestructive detection is accomplished by collecting the ions produced by the proton beam ionizing residual gas in the vacuum chamber. The amplitude of the electrical currents obtained by collecting these ions onto a variety of electrodes depends on the distribution of the protons in the beam. The characteristics of the electric signals make them suitable as inputs to computer systems. Both analog and digital techniques have been used to determine beam position and profile. These beam detection systems have been used for measuring the properties of the 50 MeV beam between the injector linac and the synchrotron ring; for studying the steering and the radial growth of the size of the beam during acceleration; and for measurements during the targeting sequences.
