What is the relationship between arc voltage and current in ion sources?

AI Thread Summary
Arc voltage and arc current are defined as the voltage and current present in the arc section of an ion source. The discussion centers on whether the potential difference between dual electrodes constitutes true arc voltage when current flows through one of the electrodes. Participants express difficulty in understanding these definitions and seek clarification. The conversation highlights the importance of understanding these concepts for applications involving ion sources. Overall, a clearer definition of arc voltage and current is needed for better comprehension in related fields.

I could not figure out definition of arc voltage and arc current. Is that true arc voltage if the potential differences between dual electrode and the current is flow through one of these electrode? any help would be appreciated.

It would appear that the arc voltage and current refer to the voltage and current in the arc section of the ion source.

Thread 'MCNP6 BURN Card Issue: Zero Burnup for Material in Fuel Assembly'

Hello everyone, I am currently working on a burnup calculation for a fuel assembly with repeated geometric structures using MCNP6. I have defined two materials (Material 1 and Material 2) which are actually the same material but located in different positions. However, after running the calculation with the BURN card, I am encountering an issue where all burnup information（power fraction(Initial input is 1,but output file is 0), burnup, mass, etc.） for Material 2 is zero, while Material 1...

Thread 'Beginner Seeking Help: MCNP6 Burnup Example (OECD-NEA Benchmark)'

Hi everyone, I'm a complete beginner with MCNP and trying to learn how to perform burnup calculations. Right now, I'm feeling a bit lost and not sure where to start. I found the OECD-NEA Burnup Credit Calculational Criticality Benchmark (Phase I-B) and was wondering if anyone has worked through this specific benchmark using MCNP6? If so, would you be willing to share your MCNP input file for it? Seeing an actual working example would be incredibly helpful for my learning. I'd be really...
