[en] Some of the existing scenarios for heavy ions drivers include accumulator, condenser and storage rings in their scheme. Because of the strong space charge forces involved, the beam is both transversely and longitudinally unstable. Therefore, in order to prevent the emittances from blowing up, one has to shorten the time the beam spends in any of these circular machines. The growth time of the instability is very short < 1 ms. Thus, it does not exist any solution to storing of the beam. This applies also to the HIBALL scenario. In this case, one has to give the existing scheme another thought keeping in mind that none of the rings is capable of storing a beam for more than 1 ms or so without an irreversible spoiling of the emittances.

[en] This article presents an overview of the work done in the area of target design for the HIBALL reactor study. We present simulation studies of compression, ignition and burn phases in a typical reactor-size ion-beam target. These simulations have been done using an updated version of a 1-D Lagrangian computer code MEDUSA. We also discuss the hydrodynamic stability of this target and the importance of radiation effects in these pellet calculations. (orig.)

[en] We present a calculation of the time dependent charge state of a heavy projectile traversing a finite temperature target. The calculation uses an average-atom model to integrate the rate equations. (orig.)

[en] Factors to be considered are: Heavy Ion RF linac and debuncher parameters, fusion target requirements, betatron stacking in the storage rings, transverse and longitudinal space charge effects and instabilities, bunch compression systems, crossing of betatron resonances, transverse and longitudinal emittance dilution effects, final transport to the fusion target.

[en] The stability of heavy ion driven inertial confinement fusion targets is investigated within a two-dimensional Eulerian hydrodynamic code. The importance of the beam geometry is studied. Following our results the HIBALL design in its present form seems to inhibit a spherical implosion of the target. It is shown that the beam angle in the HIBALL geometry should be about 35 degrees.

[en] The funneling of heavy ion beams can be achieved by first bending the beams by septum magnets towards the common axis, and then deflecting them onto the axis by rf-deflector elements with time varying electric field strength. The main properties of these deflection elements are discussed, especially the increase of the transverse emittance. As an example beam envelopes are shown for funneling two 100 mA, 1.7 MEV/N Bisup(+2) beams into one 108 MHz Alvarez accelerator. (orig.)

[en] In this talk, I describe briefly the experimental plans for the next few years in the U.S. inertial fusion program. I report on the status of the major facilities under construction, list the support facilities currently in use, and select example experiments from several of the major laboratories as illustrative of the program.
