title: Paul trap simulator experiment to model intense-beam propagation in alternating-gradient transport systems.
abstract: The results presented here demonstrate that the Paul trap simulator experiment (PTSX) simulates the propagation of intense charged particle beams over distances of many kilometers through magnetic alternating-gradient (AG) transport systems by making use of the similarity between the transverse dynamics of particles in the two systems. Plasmas have been trapped that correspond to normalized intensity parameters s=omega(2)(p)(0)/2omega(2)(q)<or=0.8, where omega(p)(r) is the plasma frequency and omega(q) is the average transverse focusing frequency in the smooth-focusing approximation. The measured rms radius of the beam is consistent with a model, equally applicable to both PTSX and AG systems. The PTSX device confines one-component cesium ion plasmas for hundreds of milliseconds, which is equivalent to over 10 km of beam propagation.
