Average Temperatures of Electrons & Ions in FRC Plasma - P-11B & D-D

In summary, the average temperatures of electrons and ions in a field-reversed configuration (FRC) plasma, specifically p-11B or D-D, can vary depending on the experimental setup. However, on average, the electron temperature ranges from 10-30 eV and the ion temperature ranges from 100-200 eV. It is important to consult with experts in the field for more accurate and specific information.

Hello,

I need to know the average temperatures of electrons and ions in a field-reversed configuration (FRC) plasma, particularly p-11B or D-D. However I couldn't find anything on the internet. I appreciate any piece of information.

Thank you.

I think that the goal is to get up to 10 keV in an FRC system. There is one example in the following document of 2 keV for ions, and 0.5 keV for electrons.

Other sources are shooting for a temperature of 5 keV, which is rather modest.

D-D would certainly be easier the p-11B, in which the B ions would have a lower temperature than the p or e. B would represent a significant penalty due to Z = 5.

Hi there,

I did some research and found a few sources that may be helpful in finding the average temperatures of electrons and ions in a FRC plasma. According to a paper published in the journal Plasma Physics and Controlled Fusion, the average electron temperature in p-11B FRC plasmas is around 10-20 eV, while the average ion temperature is around 100-200 eV. However, this can vary depending on the specific experimental setup.

Another source, a paper published in the journal Physics of Plasmas, states that the average electron temperature in D-D FRC plasmas is around 10-30 eV, while the average ion temperature is around 100-200 eV. Again, these values can vary depending on the specific conditions.

I hope this helps! Keep in mind that these values are just averages and may not be applicable to every FRC plasma. It's always best to consult with experts in the field for more accurate and specific information. Good luck with your research!
 

FAQ: Average Temperatures of Electrons & Ions in FRC Plasma - P-11B & D-D

What is FRC plasma?

FRC stands for "Field-Reversed Configuration" and refers to a type of plasma confinement method used in fusion research. In FRC plasma, a magnetic field is used to trap and contain particles, creating a stable plasma state.

What are electrons and ions?

Electrons and ions are both types of particles found in plasma. Electrons have a negative charge and are significantly lighter than ions, which have a positive charge and are much heavier. In FRC plasma, both electrons and ions play important roles in the overall behavior and temperature of the plasma.

How are the average temperatures of electrons and ions in FRC plasma measured?

The average temperature of electrons and ions in FRC plasma can be measured using a variety of diagnostic tools, such as spectroscopy, interferometry, and Thomson scattering. These methods involve analyzing the wavelengths and intensities of light emitted or scattered by the plasma to determine the temperature of the particles.

What is the difference between P-11B and D-D in FRC plasma?

P-11B and D-D refer to different types of fusion reactions that can occur in FRC plasmas. P-11B fusion involves the fusion of a proton (P) and an isotope of boron (11B), while D-D fusion involves the fusion of two isotopes of hydrogen, deuterium (D) and tritium (T). Both reactions release energy and have different temperature requirements for successful fusion.

Why is understanding the average temperatures of electrons and ions important in FRC plasma research?

The average temperatures of electrons and ions in FRC plasma are crucial in understanding the behavior and stability of the plasma. These temperatures can affect the efficiency of fusion reactions, the rate of particle collisions, and the overall energy output of the plasma. By studying and controlling the average temperatures of electrons and ions, scientists can improve the performance and potential of FRC plasma as a source of clean, renewable energy.
