“…The beam will be neutralized by electrons pulled in from the plasma lens so space-charge effects in the chamber should be small or nonexistent. An experimental effort is underway at Lawrence Berkeley National Laboratory (LBNL) to study the plasma lens and channel transport [15,161. One experiment will study the plasma lens using the LBNL 2 MeV ESQ injector [l7].…”

September 1, 1995 Abstract Chamber transport is an important area of study for heavy ion fusion. Final focus and chamberrtransport are high leverage areas providing opportunities to significantly decreke the cost of electricity from a heavy ion fusion power plant. Chamber transport in two basic regimes is under consideration. In the low chamber density regime ( 5 0.003 torr), ballistic or nearly-ballistic transport is used. Partial beam neutralization has been studied to offset the effects of beam stripping. In the high chamber density regime ( 2 .1 torr), two transport modes (pinched transport and channel transport) are under investigation. Both involve focusing the' beam outside the chamber then transporting it at small radius ( M 2 mm). Both high chamber density modes relax the constraints on the beam quality needed from the accelerator which will reduce the driver cost and the cost of electricity...

“…Pion/muon cooling by proton beams similar to electron cooling [53] is another attractive method for modulating the pion/muon beam size, although the capture or recombination problem of pion/muon by protons should be discussed carefully. The ion/plasma channel guide technique is also useful [54,55]. The induction acceleration located upstream of preaccelerators [56] is expected for a wide kinetic energy profile just after pion decay.…”

A new high-energy particle accelerator with static combined type of magnetic field and high-gradient resonant cavities is introduced for muon acceleration up to 300 MeV and proton acceleration up to 400 MeV. The accelerator concept is expected to realize Mpps-class rapid cycling high-energy particle acceleration in circular particle accelerators. Conceptual designs of the circular accelerator are discussed with an emphasis on short lifetime particles. The fundamental concept of particle acceleration and the related practical issues, which should be discussed when designing the accelerators, are described as well.

“…Applications of the plasma lens ranging from heavy ion fusion to high energy lepton colliders are discussed in Refs. [6][7][8][9][10]. In particular, both heavy ion fusion and high energy physics applications involve the transport of positive charges in plasma: partially stripped heavy elements for heavy ion fusion; positrons for electron-positrons colliders [9]; and high-density laser-produced proton beams for the fast ignition of inertial confinement fusion targets [11].…”

Scaling and formulary of cross-sections for ion–atom impact ionization

2006

View full text Add to dashboard Cite

The values of ion-atom ionization cross sections are frequently needed for many applications that utilize the propagation of fast ions through matter. When experimental data and theoretical calculations are not available, approximate formulas are frequently used. This paper briefly summarizes the most important theoretical results and approaches to cross section calculations in order to place the discussion in historical perspective and offer a concise introduction to the topic.Based on experimental data and theoretical predictions, a new fit for ionization cross sections is proposed. The range of validity and accuracy of several frequently used approximations (classical trajectory, the Born approximation, and so forth) are discussed using, as examples, the ionization cross sections of hydrogen and helium atoms by various fully stripped ions.
