Over 20 years experience in advanced development and design of novel and special nondestructive test equipment. Managed complex and challenging nondestructive test development programs solving both technical and economic challenges.
Milky Way Jewels 1996 to 1999
Chief Technical Officer
* Internet sales of Vintage and Antique Costume Jewelry.
SECOND SOUND 1996 to 1999
Chief Technical Officer
* Manufacturer of ultrasonic transducers and systems to 1 GHz. High performance ultrasonic transducer technology for commercial applications including aspherical, high-temperature, and high-frequency regimes previously not practical.
LAWRENCE LIVERMORE NATIONAL LABORATORY 1984 to 1996
* Led National program to develop nondestructive examination of containers for civilian reactor radioactive waste program. These containers must demonstrate satisfactory performance for 10,000 years, placing unusual requirements on the container design and certification.
* Initiated and carried out demonstration of x-ray photo acoustic imaging of integrated circutits at the Stanford Synchrotron Radiation Laboratory. This was the first such experiment with a source less than ten Watts/cm2.
* Obtained funding for the utilization of scanning tunneling microscopy in Nondestructive for applications in high power optical surface characterizations for the National Ignition Facility (NIF). NIF will be the largest laser in the world.
* Developed improvements to existing Acoustic Microscope that extended frequency from 100 to 1000 MHz and improved dynamic range by a factor of 64 times. This microscope can image structures in silicon integrated circuits with line spacing of 25 micrometers.
* Invented new acoustic emission transducer that could withstand the intense light pulse associated with Nova laser to help diagnose lens cracking problem.
* Developed acoustic telemetry for monitoring conditions at a drill head to allow real time control of drilling, resulting in significant savings since drilling no longer needed to be stopped for conventional monitoring.
* Demonstrated noise measurements of drilling operations at Nevada Test Site using equipment designed to survive severe environments at low costs.
* Taught workshops to designers and reulators on Welding Criteria for Radioactive Shipping Containers for the Nuclear Regulatory Commission.
GENERAL ELECTRIC CO. 1974 to 1984
* Supervised a nondestructive development laboratory providing instrument development, and maintenance to the company and contract development to the Department of Energy.
* Proposed and executed a multi-million dollar program on liquid metal breeder reactor steam generator inspection with Oak Ridge National Laboratory (ORNL), developing ultrasonic inspection methods used worldwide.
* Designed new method for detecting micro-flaws in tube-to-tubesheet weld radiographs for steam generators that was used for certification of reactor welds.
* Patented new methods of manufacturing annular phased arrays and high temperature transducers for use in breeder reactor under sodium viewing applications. This allowed electronic focusing and steering of ultrasound which created faster imaging and allowed operation at higher temperatures.
* Developed new ultrasonic robotic pipe inspection system for transition welds between carbon and stainless steel that improved flaw detectability and sizing and inspired the current piping inspection apparatus used for nuclear reactor piping inspection.
* Invented a lower cost statistical method that predicts the probability of a "false call" (detection of a flaw when one is not present) to lower cost of developing ultrasonic methods for difficult materials.
