A nondestructive test device will be developed to inspect niobium plates and niobium welds for defects which cause its superconducting properties to be quenched. high quality niobium is required for advanced machines such as future generation radio frequency particle accelerators. at present, there… More

In this proposal, we present a program of research on an original and innovative concept for ultrasonic tomographic microscopy which would be capable of providing unambiguous microscopic images for process control, nondestructive evaluation, and biomedical research. the method would involve using… More

Development of an ultrasonic, nondestructive test device for inspection of monofilament rod and potentially multifilamentary wire for superconducting magnets is the long-term goal of this project. the rod and wire to be inspected are the high critical-current conductors used in high field magnets… More

Long continuous conductors, i.e. minimum number of splice joints are highly desirable in superconducting magnet applications. at present the piece length of multifilamentary superconductor wire has been a problem and this has driven up the costs of magnets for the ssc. low ductility is a cause of… More

Manufacturing requires real-time evaluation of materials to determine structural properties, including inspection for latent defects. current off-line evaluation techniques utilize special facilities and increase costs. this project develops a multi-function robotic sonoscope (mfrs) for on-line… More
