“…There has been considerable interest both experimentally and theoretically in toroidal nonneutral plasmas, which are relevant to heavy ion accelerators [1], sources of highly stripped heavy ions [2], and thermonuclear fusion reactors [3]. These concepts are based totally on the electrostatic confinement of ions in a deep potential cavity.…”

“…Descriptions of three such sources, all of them still under development, have been published. 2,3,4 In this paper, after discussing in general terms certain features more or less common to all these sources, we describe in some detail the HIPAC Source of Highly Stripped Heavy Ions. This description covers first the general configuration and operating principles of the device.…”

The HIPAC Ion Source is a novel device intended to produce very highly stripped heavy ions; the achievement of this objective would permit the acceleration of heavy ions in relatively modest cyclotrons, linacs, etc. The problem of stripping heavy ions by successive electron impacts is discussed in general terms. The HIPAC Ion Source is then described using for illustrative purposes a nominal set of characteristic parameters. A torus 20 cm in maior radius is estimated to yield 1013 ions/s of Kr2U+ or 1011 ions/s of U60+. The current status of experimental work on the concept is briefly reviewed.

“…A few examples are electrostatic thermonuclear fusion reactor [7], heavy ion accelerator [8], source of highly stripped heavy ions [9], modified betatron [10], and stellatron [11]. The concept of a totally non-neutral ion torus, where high energy ions are confined by their own space charge field, may, being relatively free of transport losses of conventional neutral plasma, lead to an ideal thermonuclear reactor; however, this idea requires further quantitative examination, In all the earlier experiments, electron injection was achieved by the so-called inductive charging process [4] based on the principle that, in the guiding center approximation, both the electrons and the magnetic flux lines in an inductor move in the direction of Poynting's vector with the common (E x B)/S^ velocity.…”

Steady state formation of a toroidal electron cloud

et al. 1993

View full text Add to dashboard Cite

A novel scheme of injection and confinement of electrons is reported for the formation of a toroidal electron cloud in the presence of a static toroidal magnetic field. The scheme is based on the use of a combination of externally applied electric field and the self-consistent space charge field for the electron trapping and confinement. The time development of electron cloud potentials measured in the poloidal plane of the torus is presented. A potential well depth exceeding the initial kinetic energy of the electrons is observed, indicating collective effects. The effect of external field on the total charge and capacitance of the electron cloud is also presented.
