Title: Lawrence Livermore Laboratory heavy ion fusion program

Abstract

In the large fusion program at Livermore we are actively doing research in most areas of inertial confinement fusion. The areas in which we are funded for research specific to heavy ion fusion are: (1) target design; (2) energy conversion chamber design and (3) ion beam propagation in the combustion chamber. There are two main thrusts to the target design effort: (1) development of targets which are optimally suited to heavy ion fusion power production and (2) fundamental studies of the beam-target interaction.

  • A discussion is given of the accomplishments of a research effort to develop a linear accelerator system for heavy ion fusion. Cost estimates are given, and theoretical work in beam transport stability, longitudinal bunching, and final focusing is briefly described. Large aperture high current Cs/sup +1/ ion source development and multi-aperture source development are discussed. (PMA)
  • An intensive theoretical program was launched to try to understand the conditions for safe propagation of intense beam currents in focussing systems, such as continuous and interrupted solenoid lens systems, and quadrupole strong-focussing systems. Analytic methods have led to significant advances in understanding of the new problems; with computational techniques a large amount of new information has been generated on space-charge-dominated transport phenomena; also, at this time a new LBL particle numerical simulation code is almost ready to give new results. Because the Bevalac is an operating heavy ion linac and synchrotron facility with an ongoing R and D effortmore » and in expectation of imminent upgrading to bring it up to a uranium-ion capability, it was a natural choice to make an addition to these activities to examine low-..beta.. rf accelerating structures and ion sources suitable for HIF. An experimental program on intense beam propagation was briefly discussed. (MOW)« less

  • The major radiological environmental impact of the Lawrence Berkeley Laboratory is due to the operation of four particle accelerators in the pursuit of fundamental research in various disciplines including biology, chemistry, medicine, and physics. Potential sources of population exposure at the Laboratory are discussed. The major source of population exposure due to accelerator operation arises from the prompt radiation field which consists principally of neutrons and photons. Release of small quantities of radionuclides is also a potential source of population exposure but is usually an order of magnitude less significant. Accelerator produced radiation levels at the Laboratory boundary are comparablemore » with the magnitudes of the fluctuations found in the natural background radiation. Considerable effort has, therefore, been expended in understanding the magnitude of the components of natural background at the Lawrence Berkeley Laboratory, so that the magnitude of Laboratory-produced radiation may be accurately determined. Environmental monitoring of accelerator-produced radiation and of radionuclides is carried on throughout the Laboratory, at the Laboratory perimeter, and in the regions surrounding the Laboratory. The techniques and models used to calculate population exposure are described and discussed. (auth)« less
  • Four areas of concern are addressed. The first concern involves the estimates for completing the project within projected costs and schedule. Although this project has been regularly reviewed by project personnel and others, an independent cost estimate of the project with emphasis on the contingency factor would be desirable to provide assurance of the soundness of the cost and schedule estimates. The second area of concern involves the design criteria being used to protect the main building of the project against earthquakes. Where protection for the project building is less than that afforded nuclear facilities at Livermore and may bemore » inadequate to protect against earthquakes likely to occur in the area. The third area concerns the amount of contingency included in the estimated cost which has risen about 22% of the original estimated project costs. Again, an independent cost estimate could provide assurance on the reasonableness of the contingency factor. Finally, controls over at least $2 million of Government property purchased with project funds were not fully effective. This condition existed because the project followed a Livermore-wide policy of accounting for property that was inconsistent with Department instructions for budgeting, accounting for, and controlling such property. Recommendations to improve each of the matters are discussed. Comments and proposed actions by the Director of Office of Energy Research are appended. (PSB)« less
