Heavy-ion inertial fusion: comments on achievable temperatures for disk-heating experiments using proposed accelerator
Calculations suggest that experiments relating to beam deposition, focusing and transport can be performed within the context of current test-bed accelerator design proposals. Since the test beds have lower ion kinetic energy and beam pulse power as compared to reactor drivers, we achieve high-beam intensities at the focal spot by using short focal distance and properly designed beam optics. In this regard, the extremely low beam emittance of suggested multi-beam designs are very useful. Preliminary results suggest that intensities of greater than 100 TW/cm/sup 2/ are achievable. Given these intensities, deposition experiments with heating of disks to greater than 100 eV are expected. We could also expect as much as 1 to 3 kA of incident ion current on these disks with beam intensities almost comparable to that of reactor targets. Thus, if any anomalous plasma effects on deposition emerge, the conditions should be available for testing some of them. On the other hand, these deposition experiments have low ion kinetic energy per nucleon. About 4 to 5 MeV/nucleon is achievable if lighter ions such as sodium were used. But for lighter ions, plasma effects in deposition might be more severe because heavy-ion beams are more stiff.

Hyper filter-fluorescer spectrometer for x rays above 120 keV
An apparatus utilizing filter-fluorescer combinations is provided to measure short bursts of high fluence x-rays above 120 keV energy, where there are no practical absorption edges available for conventional filter-fluorescer techniques. The absorption edge of the prefilter is chosen to be less than that of the fluorescer, i.e., E/sub PRF/ < E/sub F/, contrary to the prior art technique E/sub PRF/ > E/sub F/. In this way, the response function is virtually zero between E/sub PRF/ and E/sub F/ and well defined and enhanced in an energy band of less than 1000 keV above the 120 keV energy.

Interagency Geothermal Coordinating Council fifth annual report. Final draft
Geothermal energy is the natural heat of the earth, and can be tapped as a clean, safe, economical alternative source of energy. Much of the geothermal energy resource is recoverable with current or near-current technology and could make a significant contribution both to increasing domestic energy supplies and to reducing the US dependence on imported oil. Geothermal energy can be used for electric power production, residential and commercial space heating and cooling, industrial process heat, and agricultural process applications. This report describes the progress for fiscal year 1980 (FY80) of the Federal Geothermal Program. It also summarizes the goals, strategy, and plans which form the basis for the FY81 and FY82 program activities and reflects the recent change in national policy affecting Federal research, development and demonstration programs. The Interagency Geothermal Coordinating Council (IGCC) believes that substantial progress can and will be made in the development of geothermal energy. The IGCC goals are: (1) reduce the institutional barriers so that geothermal projects can be on-line in one-half the current time; (2) make moderate temperature resources an economically competitive source of electricity; (3) remove the backlog of noncompetitive lease applications; (4) competitive lease all KGRA lands; and (5) cut the cost …
