A high temperature, solid-electrolyte fuel cell is described which uses molten rock having oxidizable constituents as a fuel. The principles of this magma fuel cell have been successfully demonstrated and power densities of 88 W/m/sup 2/ have been achieved. If power densities can be substantially increased, the magma fuel cell may find numerous applications in magma tap projects to increase the efficiency of energy extraction from magma sources or may provide the energy necessary for the electrochemical protection of the heat exchanger materials placed in the corrosive magma environment.

The report contains sections containing descriptions of the MORSE and PICTURE codes, input descriptions, sample problems, deviations of the physical equations and explanations of the various error messages. The MORSE code is a multipurpose neutron and gamma-ray transport Monte Carlo code. Time dependence for both shielding and criticality problems is provided. General three-dimensional geometry may be used with an albedo option available at any material surface. The PICTURE code provide aid in preparing correct input data for the combinatorial geometry package CG. It provides a printed view of arbitrary two-dimensional slices through the geometry. By inspecting these pictures one may determine if the geometry specified by the input cards is indeed the desired geometry. 23 refs. (WRF)

The energy loss by synchrotron radiation in electron-positron storage rings occurs in every bending magnet and is thus distributed around the ring, while the energy gain occurs at the rf cavities, which are usually lumped in only a few locations. This type of orbit distortion is usually negligibly small compared to the design allowance in existing synchrotrons and storage rings; however, in the case of the larger storage rings now being contemplated, the distortion can be substantial in comparison to beam size and is different for electrons and positrons. This difference between the two closed orbits can produce horizontal separations and crossing angles between the two beams at the interaction regions. There are at least three possible solutions to this problem. The first is to use a lattice in which the dispersion and its derivtive are zero at the interaction regions and at the locations of the rf system. The second is to use transverse electric fields to produce the necessary corrections in the orbits of the two beams. The last is to distribute the rf accelerating system around the ring in such a way that the closed orbit deviations are within acceptable limits. For studying this problem, the thin-lens …
