[Letter from Bill McCarter to Carol Wyrick, July 15, 1996]
Photocopies of evaluations and comments for the National Museum of American Art, Smithsonian Institution: An Introduction to Latino Art and Culture, dated June 26 - 28, 1996. The evaluations are rating the quality of the workshop by answering the questions of material, information, topics and other objectives that the exhibit provided. In a letter to Carol Wyrick, July 15, 1996, Bill McCarter apologies for withholding the evaluations but NTIEVA wanted to record the general comments made about the Institute. Some of the comments read as written, "I enjoyed the workshop and learned a lot." "Those of us who teach the younger students found the drawing studies to be of little relevance to the level of production appreciated [by] our students." Other comments continue with the enthusiasm of the quality of materials and the presentations, as well as offer suggestions or provide concerns about the related subject.

Beam and viewing dump positioning inside TFTR for CTS alpha-particle diagnostics
A collective Thomson scattering (CTS) diagnostic system for localized measurement of energetic ions is being developed for TFTR. This system will use a 200KW, 56GHz gyrotron and a sensitive heterodyne receiver. In addition, a key element of this system will be beam and viewing dumps which are needed to minimize detection of stray gyrotron and ECE background radiation by the receiver system. It is the purpose of this study to determine the size and location of these dumps inside TFTR taking into account beam refraction and launch and receiver antenna optics scanning. The beam dump must cover all the area in the vacuum chamber where the beam is expected to impinge, and the viewing dump must cover all the areas within the direct line of sight of the receiver antenna. The beam launch system and the receiver antenna are to be placed nearly symmetrically above and below the midplane of the tokamak vacuum vessel, respectively. The beam dump is to be placed at the bottom inside of the vacuum vessel to absorb the gyrotron beam which will be launched from a top port. The viewing dump is expected to be placed symmetrically at the top inside of the vacuum vessel, …

Studies of human mutation rates
The three objectives of the program are: To isolate by the technique of two-dimensional polyacrylamide gel electrophoresis (2-D PAGE), proteins of special interest because of the relative mutability of the corresponding gene, establish the identity of the protein, and, for selected proteins, move to a characterization of the corresponding gene; To develop a more efficient approach, based on 2-D PAGE, for the detection of variants in DNA, with special reference to the identification of a variant in a child not present in either parent of the child (i.e., a mutation); and, To continue an effective interface with the genetic studies on the children of atomic bomb survivors in Japan, with reference to both the planning and implementation of new studies at the molecular level. For administrative purposes, the program is subdivided into four sections, each under the direction of one of the four co-PIs; the progress during the past year will be summarized in accordance with this sectional structure. 1 tab.

FABRICATION OF CERAMIC INTERNAL REFLECTOR FOR THE SNAP 8 EXPERIMENTAL REACTOR
Fabrication of internal reflector pieces for the SNAP-8 core is described. These reflectors were made of BeO, with and without the addition of Sm/sub 2/O/sub 3/ as a nuclear poison. Because of the high density and dimensional tolerance requirements, the complexity of shapes, and the comparatively modest number of parts to be produced (approximately 1000), the blanks were hot pressed and subsequently machined with diamond wheels and cores. In almost all cases, the specified density of 98% of theoretical was achieved. The low eutectic temperature in the BeO--Sm/sub 2/O/sub 3/ system of about 1420 deg C necessitated special pressing parameters, which were arrived at by experimentation. A rather coarse grit size (80) was used for the diamond wheels, which resulted in very little wear to the wheels, and an extremely low dimensional rejection rate on the blanks. Because of the toxicity of BeO, all equipment was enclosed, and was held under negative pressure. (auth)

Utilization of coal associated minerals. Quarterly report No. 10, January 1-March 31, 1980
In the preceding quarterly report, it was reported that while sampling the Solvent Refined Coal II (SRC II) pilot plant at Fort Lewis, Washington, the plant went down and vacuum bottoms waste material representing the minerals flow at the last steady state condition were obtained. This plant has been sampled again and samples of the incoming feed coal, sized coal and vacuum bottoms waste material were obtained. As part of our effort to trace the same mineral suite through mining, preparation and conversion, new samples of feed coal, cleaned coal and refuse were obtained from the District 4 commercial preparation plant. This preparation plant supplies coal to the SRC II pilot plant at Fort Lewis, Washington. A study of the thermal insulating properties of fired flyash based structural materials was completed and is included.

Structural and electronic studies of defects in amorphous silicon. Technical progress report, March-May 1980
Proton magnetic resonance data are presented for plasma-deposited amorphous Si:H as a function of annealing temperature up to 650/sup 0/C. The data indicate that hydrogen diffuses internally before major evolution occurs, that transfer of hydrogen occurs from a heavily clustered phase to a dilute phase coincident with evolution and that evolution occurs initially from the heavily clustered phase. Comparison with infrared data indicates that the heavily clustered phase can be either SiH/ sub x/t = 2,3) or SiH.

Bioethical perspective on acceptable-risk criteria for nuclear-waste management
Wisely managing the profound human and environmental risks of nuclear wastes requires complex moral and ethical judgments. Whereas traditional ethics is limited to interpersonal relations, a new system of ethics--bioethics--concerns man's relation with nature. Environmentalists claim that technology has upset the balance of nature, that nature is sacred and has inviolable rights, and that man must therefore regulate his behavior to conform to earth's limited carrying capacity. They also say that Judeo-Christian monotheism and anthropocentrism have sanctioned the exploitation of nature in the West, whereas Eastern religions teach adaptation to nature. Evidence suggests, however, that the balance of nature is neither absolute nor precarious, but is continually changing. Moreover, technology has brought more good than harm to man, and man's needs should supersede nature's. Other evidence indicates that the earth's resources may be neither limited nor nearly exhausted. Persuasive arguments also demonstrate that man's relation with nature is not traceable to religious assumptions. In assessing the risks/benefits of nuclear-waste management, we should avoid risks that jeopardize the rights of future generations without imposing excessive sacrifices on the present generation.

The U5. 0 Undulator for the ALS
the U5.0 Undulator, and 89 period, 5 cm period length, 4.6 m long insertion device has been designed, is being fabricated and is scheduled for completion in early 1992. This undulator will be the first high brightness source, in the 50 to 1500 eV range, for the Advanced Light Source (ALS) at the Lawrence Berkeley Laboratory. A hybrid magnetic configuration using Nd-Fe-B permanent magnet material and vanadium permendur poles has been selected to achieve the field quality needed to meet performance requirements. The magnetic structure is modular with each half consisting of 5 assembly sections, which provide the periodic structure, and end structures, for entrance and exit correction, mounted on a steel backing beam. Each assembly section consists of 35 half-period pole assemblies bolted to a mount. The required 0.837 Tesla effective peak field at a 1.4 cm gap has been verified with model measurements. Vertical field integral correction is accomplished with the end structures, each having an arrangement of permanent magnet rotors which will be adjusted to minimize electron beam missteering over the undulator operating field range. To reduce the effect of environmental fields, the steel backing beams are connected through parallel, low-reluctance, Ni-Fe hinges. The magnetic structure is …
