Removal of silica from Raft River geothermal water

Description: Lack of sufficient quantities of clean surface or near-surface water at Raft River for cooling purposes dictates that cooled geothermal fluid, effluent from the Raft River 5 MW(e) Pilot Power Plant, must also be used as condenser coolant. Prior testing revealed that a water-treatment system would be required to reduce silica and calcium concentrations of the cooling fluid. The water-treatment system specified was to use dolomitic lime for both pH adjustment and source of magnesium. The dolomiti… more

Use of hodoscopes at ISABELLE

Description: A major problem for experimenters designing detectors for use at ISABELLE is the high interaction rate, one event every 25 nanoseconds at a luminosity of 10/sup 33/ cm/sup -2/ sec/sup -1/. Typical multiplicities range from a few at large angles (> approximately 45/sup 0/) to approximately 10 nearer the forward direction. This implies average rates as high as a particle every few nanoseconds. For experiments which require high luminosities, detectors must be designed which have very short (appro… more

Computer Facilities for Isabelle Data Handling

Description: The analysis of data produced by Isabelle experiments will need a large system of computers. Included in the array should be a substantial computer system at each Isabelle intersection in use. These systems must include enough computer power to keep experimenters aware of the status of the experiment. This will require at least one very fast sophisticated processor in the system, the size depending on the experiment. Other features of the intersection systems must be a good, high speed graphic … more

Parametric systems analysis of the Modular Stellarator Reactor (MSR)

Description: The close coupling in the stellarator/torsatron/heliotron (S/T/H) between coil design (peak field, current density, forces), magnetics topology (transform, shear, well depth), and plasma performance (equilibrium, stability, transport, beta) complicates the reactor assessment more so than for most magnetic confinement systems. In order to provide an additional degree of resolution of this problem for the Modular Stellarator Reactor (MSR), a parametric systems model has been developed and applied… more

Plasma physics aspects of ETF/INTOR

Description: In order to achieve their principle technical objectives, the Engineering Test Facility (ETF) and the International Tokomak Reactor (INTOR) will require an ignited (or near ignited) plasma, sustained for pulse lengths of at least 100 secs at a high enough plasma pressure to provide a neutron wall loading of at least 1.3 MW/m/sup 2/. The ignited plasma will have to be substantially free of impurities. Our current understanding of major plasma physics characters is summarized.

SLAC low emittance accelerator test facility

Description: SLAC is proposing to build a new Accelerator Test Facility (ATF) capable of producing a 50 MeV electron beam with an extremely low geometric tranverse emittance (1.5 x 10/sup -10/ rad.m) for the purpose of testing new methods of acceleration. The low emittance will be achieved by assembling a linear accelerator using one standard SLAC three-meter section and a 400 kV electron gun with a very small photocathode (40 microns in diameter). The photocathode will be illuminated from the back by short… more

Comparison of standing-wave and traveling-wave structures

Description: The controversy over the relative advantages of standing-wave and traveling-wave linear accelerators is now in its fourth decade. It has been fed by a considerable body of misinformation. The author hopes in this paper to shed some light on the subject, and expose some of the falsehoods. The discussion is directed toward the question of which structure to use for short pulse high field electron accelerators since it is almost universally accepted that standing-wave structures are appropriate fo… more

Recent progress in relativistic klystron research

Description: Experimental work is now under way by collaborators at LLNL, SLAC, and LBL to investigate relativistic klystrons as a possible rf power source for future high-gradient accelerators. We have learned how to overcome our previously reported problem of high-power rf pulse shortening and have achieved peak rf power levels of 290 MW. We have used the rf from a relativistic klystron to power a short, 11.4-GHz high-gradient accelerator. The measured momentum spectrum of the accelerated electron beam co… more
