Abstract:
The company currently produces a Reverse Geometry X-Ray
System that is used in various non-destructive evaluation
applications. In order to image aluminum and composites thicker
than five centimeters, additional non-destructive probing energy
is necessary. This project will perform the necessary research and
development to determine the factors limiting the operative
kilovoltage of the present 100 kV system, implement changes to
achieve 125-135 kV, and evaluate the requirements for obtaining
160 kV and beyond. The high voltage level of the present system
will be increased by small increments until nonreliable operation
occurs. Evaluation of failure(s) in reliability will orient the
development program to augment system potential. A new power
supply will be procured for operation at higher kV levels.
Components for system focus, feedback, tube performance, and
system stability will be redesigned and assembled. The improved
imaging capability of the system will be evaluated with NASA
specimens and other aerospace coupons. If Phase I is successful,
Phase II will explore obtaining a 160 kV level.
Potential Commercial Application:
Potential Commercial Applications: Applications include non-
destructive testing of turbine blades; aging aircraft and
spacecraft; welds, braises, and castings; aerospace materials;
automotive aluminum engine casings; air bag units; electronics
(surface mount solder joints, ceramic circuit boards, advanced and
hybrid packages); and fuses.
