Ion-beam inertial fusion: the requirements posed by target and deposition physics
The demonstration of ICF scientific feasibility requires success in target design, driver development and target fabrication. Since these are interrelated, we present here some results of ion beam target studies and relate them to parameters of interest to ion accelerators. Ion deposition physics have long been a well known subject apart from high beam currents. Recent NRL experiments at up to 250 kA/cm/sup 2/ ions confirm the classical deposition physics now at current densities which are comparable to most ion targets. On the other hand, GSI data at low current density but 1 to 10 MeV/nucleon are continually being accumulated. They have yet to find anomalous results. Relying on target concepts outlined briefly, we report on the energy gain of ion-driven fusion targets as a function of input energy, ion ranges and focal spot radius. We also comment on some consequences of target gain versus driver and reactor requirements.

Energies of organic compounds. Technical progress report. [Ketals, orthoesters, norbonyl ketals]
Two automated reaction calorimetry systems were built and tested. The first made use of a quartz thermometer probe as the temperature measuring element. The second was constructed using a thermister which was part of a Wheatstone bridge. The off-balance voltage from the bridge was measured using the 6 1/2 digit digital voltmeter, and transferred to the microprocessor. The one disadvantage of the first system is the relatively large size of the quartz sensor. The calorimeter systems were used to measure: the enthalpies of hydrolysis of ketals, acetal, orthoesters, enthalpies of hydration of alkenes; enthalpies of formation of small ring hydrocarbons.

Free-electron laser using rf-coupled accelerating and decelerating structures
A free electron laser and free electron laser amplifier using beam transport devices for guiding an electron beam to a wiggler of a free electron laser and returning the electron beam to decelerating cavities disposed adjacent to the accelerating cavities of the free electron laser. Rf energy is extracted from the electron beam after it emerges from the wiggler by means of the decelerating cavities which are closely coupled to the accelerating cavities, or by means of a second bore within a single set of cavities. Rf energy extracted from the decelerated electron beam is used to supplement energy provided by an external source, such as a klystron, to thereby enhance overall efficiency of the system.

High-temperature electrically conductive ceramic and method for making same
It is the primary objective or aim of the present invention to provide an electrically conductive composition for the fabrication of susceptors useful for induction melting of uranium and uranium alloys and to also provide such a composition for forming crucibles and other containment vessels utilized to contain uranium at elevated temperatures. This composition does not appear to interact with molten uranium, since there is no significant reaction between the compositional consituents of the susceptor or containment vessel and the confined uranium. This objective is achieved by utilizing a sintered ceramic composition which consists essentially of about 13-67 vol. % of a refractory metal carbide and a nonconductive oxide selected from a group consisting of zirconium oxide, calcium aluminate, yttria, and combinations thereof.

Brayton-cycle heat-recovery system characterization program. Component test plan
The critical components of the glass furnace subject to corrosion/erosion are: the valve gate and the valve seat bottom and sides which can also be subject to warpage causing subsequent leakage and the furnace flues (or ducting). The Brayton System will be added to the glass furnace just downstream of the reversal valve. Hence, the inlet air to the flues will no longer be at ambient temperature but at a higher level between 800 to 1000/sup 0/F. Also, the exhaust gas for the Brayton System is required to be 1500 to 1600/sup 0/F at these locations. Thus, the flues and valve components will be exposed to a much higher average temperature operating with the Brayton System. The possibility of cracking of the refractory linings and warpage and scaling of the switching valve, with consequent leakage to the exhaust stream should be avoided or decreased as much as feasible because of its effect of lowering the turbine inlet temperature and thus the total system value. On the inlet side, leakage dilutes the heat added to the air (which is preheated) and reduces the expected fuel savings. Assessment of such effects and determination of potential solutions and/or improvements in these areas is …
