Experience

High Voltage, Pulsed Power Research and Development (20 years)

Led the imploding-foil-plasma, SHIVA experiments (U. S. Air Force Weapons Laboratory).
Performed exploding-foil, opening switch experiments (U. S. Air Force Weapons Laboratory).
Designed and developed the replacement Marx generator for the HERMES II accelerator (Sandia National Laboratories).
Designed and developed a repetitively pulsed accelerator with a repetition rate of 500 Hz and an average power of 25 kW (Sandia National Laboratories).

Pulsed Electron-Beam Source Development (16 years)

A short pulse, high dose-rate mode on the HERMES II accelerator (Sandia National Laboratories).
The triaxial diode on the HydraMITE accelerator (Sandia National Laboratories).
The pentaxial diode used on the SPEED accelerator (Sandia National Laboratories). This technology led to the ring diode, presently used on Saturn, which is the premier X-ray effects simulator in the world today.
A long-pulse, repetitive, thermionic cathode using a PHERMEX diode (Sandia National Laboratories).
A multimillion shot, high-repetition-rate, long-lived cathode (Sandia National Laboratories).

Radiation Protection and Radiation Transport (24 years)

Extensive experience with radioactive sources and radiation producing machines.
Wrote a computer code to calculate radiation produced by an electron beam.
Designed the radiation protection enclosures for three, high-average-power, electron-beam accelerators.
Completed several courses in radiation safety, and am familiar with the concept of ALARA (As Low As Reasonably Achievable).

Experimental Nuclear Physics Research (4 years)

Measured total, nuclear reaction cross sections (Northwestern University and Argonne National Laboratory).

Project Management (25 years)

Project officer for the imploding plasma experiments on the 1 MJ SHIVA capacitor bank at the U. S. Air Force Weapons Laboratory.
Directed the $0.5 M project to replace the Marx generator in the HERMES II accelerator at Sandia National Laboratories.
Oversaw the final stages of bringing the REBA accelerator on line at the White Sands Missile Range for the U. S. Army.
Acted as my own contractor for the construction of my house.
Developed a project plan for a software company to create a payroll product.

C/C++ Language Programming (10 years)

Control the Data Acquisition Instruments, Event Counters, and Delay Generators associated with a repetitively pulsed experiment. This code analyzes the data in real time and takes actions to control the experiment, in real time, based on the results of that analysis. (PC / MS DOS)
Analyze signal distortion by a transmission line and correct for that distortion. (PC / MS Windows)
ASCII communications code that allows users on two computers to communicate via the serial (RS-232) port. The users can type simultaneously, and the text is printed on both computers' monitors. (PC / MS DOS / MS Windows)
Many codes that analyze and model experiments. The results are displayed in graphical form on the monitor or a printer. (PC / MS DOS)

Productivity Software for Personal Computers (17 years)

Spreadsheets: LOTUS 1-2-3, MS Excel.
Word Processors: Microsoft Word, WordMARC.
Data Base Managers: Fox Pro, MS Access, dBASE III Plus.
Presentation Graphics: Harvard Graphics, Freelance.
Project Management: MS Project, Harvard Total Project Manager.
CAD: AutoCAD.
Operating Systems: MS DOS, MS Windows, MS Windows 95.

Data Base Management Programming (6 years)

Made major modifications and upgrades to the accounting package used by an Albuquerque business. This package runs under Fox Pro on a PC Local Area Network (LAN).
Used Visual Fox Pro to create a job estimating application designed for an contractors. This runs under MS Windows, and it is available for purchase.
Used MS Access to create an activity account management system for local high school.

FORTRAN Programming (33 years)

Predict the behavior of exploding metal foils (fuses). This code generates a 16 mm color movie depicting the electrical behavior of the fuse. (Mainframe)
Calculate the range and energy loss rate of subatomic particles in matter. (Mainframe)
Calculate the radiation shielding required for a high-power, X-ray generator. (PC / MS DOS)
Many codes that analyze and model experiments. The results may be displayed in graphical form on a paper plotter, microfilm plotter, the monitor, or a printer. (Mainframe, VAX / VMS, PC / MS DOS)
Many other codes. (Mainframe, VAX / VMS, PC / MS DOS)

Computer Operating Systems

Linux/UNIX: Red Hat, Mandrake, Solaris (1 year, 6 hours college credit)
Windows NT (2 years)
Windows 95, 98 (5 years)
MS DOS (17 years)
VAX/VMS (10 years)
Mainframe operating systems: CDC (Scope, NOS, NOS/BE, etc.), IBM (20 years)
