3. Which best describes your background? *

PhD in a directly relevant technical fieldBS or MS in a relevant technical field plus 5 or more years of directly relevant professional experienceNeither

4. Have you personally designed, built, commissioned, or tested high voltage power electronics or pulsed power hardware operating at approximately 10 kV or above? *

YesNo

5. Have you personally owned the engineering of a high voltage power supply, pulse modulator, pulsed power system, or a major subsystem, from design into hardware test? *

Technical evidence

6. The highest power hardware you personally worked on *

Give maximum voltage, peak current, peak power, average power, pulse width and repetition rate if pulsed, and your personal contribution. Use actual numbers and units.
