Abstract Starting from the principle of least action, we derive a general Hamiltonian that describes the collective motion of an intense charged-particle bunch in a drift-tube linear accelerator. The Alvarez-type structure is assumed as an example, but the present theory can readily be extended to other types of conventional linacs. A Hamiltonian formalism of non-neutral plasma in a linear Paul trap is also constructed, which demonstrates clear similarity between the linac system and compact ion-trap system. The physical equivalence between these two dynamical systems can be employed to perform a fundamental design study of high-intensity hadron linacs in a local tabletop environment. For the tabletop experiment on space-charge effects in short proton and heavy-ion bunches, we have designed an ion trap whose overall dimension is less than 10 cm axially and whose aperture size is 1 cm in diameter. The new trap is introduced in the S-POD (Simulator of Particle Orbit Dynamics) apparatus developed at Hiroshima University for “Laboratory Accelerator Physics.”

The subject of space charge in ionization detectors is reviewed, showing how the observations and the formalism used to describe the effects have evolved, starting with applications to calorimeters and reaching recent, large time-projection chambers. General scaling laws, and different ways to present and model the effects are presented. The relations between space-charge effects and the boundary conditions imposed on the side faces of the detector are discussed, together with a design solution that mitigates some of the effects. The implications of the relative size of drift length and transverse detector size are illustrated. Calibration methods are briefly discussed.
