Sample interview questions: Can you discuss any experience you have with plasma diagnostics based on Langmuir probes?
Sample answer:
Langmuir Probe Diagnostics Experience
I possess extensive experience in plasma diagnostics using Langmuir probes, a versatile technique for characterizing plasma parameters such as electron temperature, density, and space potential. I have successfully employed Langmuir probes in various plasma environments, including high-pressure arc plasmas, low-temperature glow discharges, and fusion plasmas.
My experience includes:
-
Design and fabrication of Langmuir probes: I have designed and fabricated custom Langmuir probes tailored to specific plasma conditions and measurement requirements. These probes typically consist of a cylindrical or spherical tip mounted on an insulating substrate with a wire lead for electrical connection.
-
Probe insertion and retrieval: I am proficient in the careful insertion and retrieval of Langmuir probes into and out of plasma devices, ensuring minimal disturbance to the plasma and maintaining probe integrity.
-
Signal acquisition and analysis: I have developed and implemented data acquisition systems for… Read full answer
