New Regenerator Materials for use in pulse tube coolers

Description: A two-stage pulse tube cooler driven by a linear compressor is being developed to provide cooling at 20 K. The first stage of the cooler will have the conventional stainless steel screen regenerator matrix. The matrix for the second stage regenerator (<60 K) will be made from a new class of Er based alloys which was recently developed at Ames Laboratory, in Ames, Iowa. These alloys exhibit heat capacities that exceed that of all other materials, including lead, over a Wide range in temperature (15 K < T C 85 K). The performance of one such alloy was shown to be better than lead when tested in a single-stage pulse tube cooler driven by a G-M compressor and operating at 2 Hz. An effort is underway to establish their suitability at frequencies above 40 IIZ. An approach to testing these alloys at low temperatures while using a low-power linear compressor is presented.

Midwest Forensics Resource Center Project Summary June 2005

Description: The mission of the MFRC Research and Development Program, is to provide technological advances in forensic science for the benefit of our regional partners as well as the forensic community at large. Key areas of forensic science need are identified through our interactions with our Midwest partners and our R&D advisory group, as well as through our participation in national meetings in forensic science. Under the sponsorship of the National Institute of Justice, the MFRC solicits proposals for the development of practical and useful technology, instrumentation, and methodology that address needs in areas related to forensic science and its application to operational crime laboratories. The MFRC facilitates proposal development by working to establish partnerships between researchers and our regional partners. The MFRC administers a peer-review of the proposals and then funds the selected projects at a cost of approximately $55,000 each, with a 12-month period of performance. The process for selection of these projects includes the following steps: (1) drafting of a call for proposals by MFRC staff, (2) review of the draft call by members of the R&D advisory committee, (3) review and approval of the call by NIJ, (4) issuance of the call to ISU, Ames Laboratory, regional partners, and research organizations, (5) receipt of proposals, (6) review of proposals by R&D advisory committee, (7) ranking and selection by MFRC staff using advisory committee reviews, with concurrence by NIJ, (8) notification of proposers, (9) receipt and review of progress reports by MFRC, (10) receipt and review of final reports by MFRC, R&D advisory committee, and NIJ. The decision to fund any specific project is based upon a peer-reviewed call-for-proposal system administered by the MFRC. The reviewers are crime laboratory specialists and scientists who are asked to rate the proposals on four criteria areas including: (1) relevance to the ...

Ames Laboratory integrated safety management self-assessment report

Description: The implementation of Integrated Safety Management (ISM) at Ames Laboratory began with the signing of the ISM Implementation Charter on February 24, 1997 (see Appendix A). The first step toward implementation of ISM at Ames Laboratory is the performance of a Self-Assessment (SA). In preparation for the SA, a workshop on ISM was provided to the Laboratory`s Environment, Safety, and Health (ES&H) Coordinators, Safety Review Committee members, and the Environment, Safety, Health and Assurance (ESH&A) staff. In addition, a briefing was given to the Laboratory`s Executive Council and Program Directors. Next, an SA Team was organized. The Team was composed of four Ames Laboratory and four Department of Energy-Chicago Operations Office (DOE-CH) staff members. The purpose of this SA was to determine the current status of ES&H management within Ames Laboratory, as well as to identify areas which need to be improved during ISM implementation. The SA was conducted by reviewing documents, interviewing Ames Laboratory management and staff, and performing walkthroughs of Laboratory areas. At the conclusion of this SA, Ames Laboratory management was briefed on the strengths, weaknesses, and the areas of improvement which will assist in the implementation of ISM.

U.S. Department of Energy Office of Inspector General report on audit of acquisition of scientific research at Ames Laboratory

Description: The Department awards grants and cooperative agreements and contracts to sponsor scientific research at colleges and universities. Compared to cooperative agreements, contracts, particularly management and operating contracts, often impose duplicative and/or unnecessary administrative and compliance burdens on a college or university. Since the Department bears the cost of those additional burdens, the authors audited the cost effectiveness of the Department`s sponsorship of research at Ames Laboratory under a management and operating contract with Iowa State University. The research conducted at Ames is of the type that Congress intended to be sponsored by assistance agreements, rather than contracts. Moreover, they found the contract for managing and operating Ames Laboratory caused micromanagement and unnecessary costs, most of which could have been avoided with a cooperative agreement. However, after completion of the field work, the Department announced initiatives to reduce or eliminate some compliance and oversight burdens associated with management and operating contracts, but did not opt to sponsor research under cooperative agreements. The authors are unable to determine the monetary impact because the initiatives have not been implemented. Nevertheless, they continue to believe that cooperative agreements, having fewer unique bureaucratic requirements, offer the potential for reducing administrative overhead.

Plasma Sprayed Pour Tubes and Other Melt Handling Components for Use in Gas Atomization

Description: Ames Laboratory has successfully used plasma sprayed ceramic components made from yttria stabilized zirconia as melt pouring tubes for gas atomization for many years. These tubes have proven to be strong, thermal shock resistant and versatile. Various configurations are possible both internally and externally. Accurate dimensions are achieved internally with a machined fugitive graphite mandrel and externally by diamond grinding. The previous study of the effect of spray parameters on density was extended to determine the effect of the resulting density on the thermal shock characteristics on down-quenching and up-quenching. Encouraging results also prompted investigation of the use of plasma spraying as a method to construct a melt pour exit stopper that is mechanically robust, thermal shock resistant, and not susceptible to attack by reactive melt additions. The Ames Laboratory operates two close-coupled high pressure gas atomizers. These two atomizers are designed to produce fine and coarse spherical metal powders (5{mu} to 500{mu} diameter) of many different metals and alloys. The systems vary in size, but generally the smaller atomizer can produce up to 5 kg of powder whereas the larger can produce up to 25 kg depending on the charge form and density. In order to make powders of such varying compositions, it is necessary to have melt systems capable of heating and containing the liquid charge to the desired superheat temperature prior to pouring through the atomization nozzle. For some metals and alloys this is not a problem; however for some more reactive and/or high melting materials this can pose unique challenges. Figure 1 is a schematic that illustrates the atomization system and its components.
