Is the Fusor or Plasma Focus a Realistic Option for Controlled Fusion?

AI Thread Summary
Controlled fusion reactors, such as the fusor and plasma focus, face significant challenges, particularly regarding electrode contamination and erosion. The fusor's electrodes cannot effectively manage the plasma's potential, leading to direct contact that compromises both the plasma quality and the electrodes themselves. Plasma focus devices operate in a pulsed mode and also struggle with similar issues of electrode erosion and plasma contamination. The feasibility of using fuels like pB11 or D-He3 in these systems remains uncertain due to these technical limitations. Overall, while innovative designs exist, the fundamental problems in electrode performance hinder progress in controlled fusion technology.

PLEASE INFORM ME ABOUT THE CONTROLLED FUSION REACTOR.

Is possible the continuos use the fusor and plasma focus, using fuel : pB11 or D-He3.

Please send me information.

Best Regards

Major Problem with Fusor Electrodes
There are a number of unsolved, and possibly unsolvable, problem with the electrodes in a fusor power system. To begin with, the electrodes cannot influence the potential within themselves, so that the fusion plasma will be in more or less direct contact with the the inner electrode, resulting in contamination of the plasma and destruction of the electrode. Also, the transparency of the electrode will have to be unbelievably good since an ion will have to pass through it on the order of 1010 times before undergoing a fusion reaction.

As for Plasma Focus - this is essentially a magneto-plasmadynamic (MPD) device, and it operates in a pulsed mode. I have reviewed information provided by http://focusfusion.org and found claims to be highly questionable. MPD's also suffer from elctrode erosion and contamination of the plasma.
 
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...
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...
