Heavy ion inertial fusion: Initial survey of target gain versus ion-beam parameters

A Scaled Beam-combining Experiment for Heavy Ion Inertial Fusion

Transverse beam combining is a cost-saving option employed in many designs for induction linac heavy ion fusion drivers. The resultant transverse emittance increase, due predominantly to anharmonic space charge forces, must be kept minimal so that the beam remains focusable at the target. A prototype combining experiment has been built and preliminary results are presented. Four sources each pr...

Heavy Ion Beams for Inertial Fusion

The United States' program in inertial confinement fusion (ICF) is described in this paper, with emphasis on the studies of the use of intense high energy beams of heavy ions to provide the power and energy nkeded to initiate thermonuclear burn. Preliminary calculations of the transport of intense ion beams in an electrostatic quadrupole focussing structure are discussed. In a companion paper i...

Beam Dynamics in Heavy Ion Fusion

for current multiplication, and it is there that the main challenges of beam dynamics are found. It is being studied in Europe, Russia, and Japan, and is discussed in ref. [1]. A standard design for heavy ion fusion drivers under study in the US. is an induction linac with electrostatic focusing at low energy and magnetic focusing at higher energy. The need to focus the intense beam to a fewmil...

Beam Imaging Diagnostics for Heavy Ion Beam Fusion Experiments*

We are developing techniques for imaging beams in heavy-ion beam fusion experiments in the HIF-VNL in 2 to 4 transverse dimensions. The beams in current experiments range in energy from 50 keV to 2 MeV, with beam current densities from <10 to 200 mA/cm, and pulse lengths of 4 to 20 μs. The beam energy will range up to 10 MeV in near-future beam experiments. The imaging techniques, based on kapt...
