Low-Cost Solar Array Project. Task I. Silicon material: investigation of the hydrogenation of SiCl/sub 4/. Fifth quarterly report

Description: Reaction kinetic measurements on the hydrochlorination of SiCl/sub 4/ and mg silicon metal in the presence of a copper catalyst were last reported as a function of reaction temperature, reactor pressure and H/sub 2//SiCl/sub 4/ ratio, 3 SiCl/sub 4/ + 2 H/sub 2/ + Si ..-->.. 4 SiHCl/sub 3/. The same reaction was repeated at a lower catalyst loading of 2 wt%. In the presence of 2 wt% cuprous chloride (based on silicon metal), the hydrochlorination reaction rate is doubled to give about the sam… more

Comparison between calculation and measurement of energy deposited by 800 MeV protons

Description: The High Energy Transport Code, HETC, was obtained from the Radiation Shielding Information Center (RSIC) at Oak Ridge National Laboratory and altered as necessary to run on a CDC 7600 using the LTSS software in use at LLNL. HETC was then used to obtain calculated estimates of energy deposited, for comparison with a series of benchmark experiments done by LLNL. These experiments used proton beams of various energies incident on well-defined composite targets in good geometry. In this report, tw… more

CAMAC serial highway interface for the LSI-11

Description: A CAMAC Serial Highway Interface has been designed for the Local Control and Instrumentation System of the Mirror Fusion Test Facility. There are over 50 distinguishable systems in the facility, each of which consists of the LSI-11 computer, fiber optic communication links, and the CAMAC system. The LSI-11 computer includes a 32k memory, serial modem interface and the CAMAC Serial Highway Interface.

Defluoridation study for Boise geothermal water

Description: Methods of removing fluorides from water are reviewed and recommendations are made for treating geothermal water used by the Boise Geothermal Project, Boise, Idaho. The Boise geothermal water except for its high fluoride content would be high quality, suitable for primary drinking water. Fluoride ranges from about 15 to 25 mg/l in water from various wells in the Boise region where the Project plans to obtain hot water. Four techniques for removing fluorides from water have been studied extensiv… more

Microchannel plate as a detector of minimum ionizing particle

Description: Micro-channel plate multipliers have been used to detect the passage of relativistic charged particles. Measurements of the detection efficiency and pulse height response versus micro-channel plate gain are presented for one, two and three micro-channel plate arrays. The probability of detecting an avalanche on the detector anode per one channel of MCP crossed by the relativistic particle was calculated. Temporal response and time jitter were measured and are reported. The track images of beam … more

Beam loss by collimation in a neutralizer duct

Description: Beam fractions lost by collimation in a neutralizer duct are computed in x-x' phase space by using three examples of slab beam distributions under a broad range of duct dimensions, beam half-widths, and beam divergences. The results can be used to design compact neutralizers and to specify beam requirements. The computer code ILOST can be used under a broad range of beam conditions to compute the fraction lost by collimation.

Serial interprocessor communications system

Description: A serial communications system based on the EIA RS232-C standard with modem control lines has been developed. The DLV11-E interface is used for this purpose. All handshaking is done with the modem control lines. This allows totally independent full duplex communication. The message format consists of eight bit data with odd parity and a sixteen bit checksum on the whole message. All communications are fully interrupt driven. A program was written to load a program into a remote LSI-11 using the… more

Practical aspects of rf acceleration for MFE injection

Description: Several practical aspects of rf acceleration (by a MEQALAC accelerator, for example) of positive and negative ions for MFE neutral injection were considered. The beam transport, gas flow, differential pumping, and compatibility with MFE beam lines were examined. It was found that rf acceleration has several advantages over dc acceleration, especially if high energy (over 100 keV) and/or high purity (over 99%) is required. Therefore rf acceleration should be considered especially in connection w… more

Rutherford scattering of neutral atoms: a technique for measuring plasma ion temperatures. An analysis of the applicability to the central cell plasma of TMX

Description: Rutherford scattering of neutral particles by plasma ions is examined as a method for determining plasma ion in the central cell fo the Tandem Mirror Experiment (TMX). When a scattering configuration, consisting of a 20-keV-, 10-A-deuterium neutral beam and an energy analyzer with a 1% resolution, is arranged such that only neutral particles scattered by plasma ions over an angle of 10/sup 0/ are accepted, central-cell ion temperatures in the 30- to 1000-eV range can be measured. The count rate… more

CO/sub 2/-laser polishing of fused silica surfaces for increased laser damage resistance at 1. 06. mu. m

Description: Bare fused silica surfaces were prepared by subjecting the mechanically polished surface to a rastered cw CO/sub 2/ laser beam. Analysis shows that this processing causes: (a) removal of a uniform layer of fused silica; and (b) a probable re-fusing or healing of existing subsurface fractures. The fused silica removal rate is found to be a function of the laser intensity and scan rate. These surfaces are seen to have very low scatter and to be very smooth. In addition, they have exhibited entran… more

Local energy transfer to TLDS by neutrons and photons

Description: The local energy transferred from neutrons and photons to TLD materials with respect to energy transferred to biological tissues or air has been calculated. Experimental response of TLDs was measured for photons with energies above 1.5 keV.
