The feasibility of constructing media with high acoustic transmissivity for all frequencies will be evaluated. program objectives are (1) to determine theoretically the acoustic velocity profile that gives maximum transmissivity, (2) to design flat test panels based on (1), and (3) to make test… More

The innovative proposed here is the development of a new type of radiation-discriminating, long-wavelength infrared (lwir) detector based on impurity-band-conduction (ibc). the new configuration enables one to discriminate between gamma-ray and lwir-induced events. past use of ibc photodetectors has… More

The problem being addressed by phase i of this project is the development of a new type of low cost robotic acoustic sensor that provides for (1) efficient coupling of the sensor piezoelectric element to air with the consequent increased range of operation and (2) minimal array crosstalk for sensors… More

40642 November 12, 1996 American Magnetics, Inc. High temperature superconducting (HTS) current leads are important to products such as magnetic resonance imaging systems where they are used to minimize heat loads. However, the leads have virtually… More

DESCRIPTION (Verbatim from the Applicant's Abstract): The specific aims of this Phase I STTR project, proposed by the American Magnetics, Inc. in partnership with the MIT Francis Bitter Magnet Laboratory, are: 1) experimental demonstration of feasibility of innovative… More

79359S05 There is an urgent need at neutron user-facilities worldwide to eliminate problems caused by magnetic stray fields from high-field, split-pair superconducting magnets. There is also a growing demand within the neutron scattering community for high-field, split-pair magnets that can be used… More
