S-POD (Simulator of Particle Orbit Dynamics) is a tabletop experimental apparatus developed at Hiroshima University for systematic studies of various beam dynamic effects in modern particle accelerators. This novel experiment is based on an isomorphism between the basic equations governing the collective motion of a non-neutral plasma in a trap and that of a charged-particle beam in an alternating-gradient (AG) focusing channel. The system is particularly useful in exploring space-charge-induced collective phenomena whose accurate study is often troublesome in practice or quite time-consuming even with high-performance computers. The present talk addresses recent experimental results on the stability of intense hadron beams traveling through long periodic AG transport channels. Emphasis is placed upon coherent resonances that occur depending on the lattice design, beam intensity, error fields, etc.
