Plasma consists of ions, which are all charged (and the basis for any confinement scheme). Fusion is only occurring between the nuclei, so if some electrons were lost, that wouldn't seem to be prohibitive. It seems clear to me that it wouldn't work to strip out all of the electrons simply...
Clearly confinement alone is insufficient. You also need temperature on the order of 108K to generate high energy collisions (as you mention), plasma of high enough density that collisions occur frequently for a long enough time to have a good probability of some of them resulting in fusion...
I guess I'm trying to figure out why (from what I can tell) there are no electrostatic fields employed in a tokamak when such fields are so useful in trapping ions. It seems that great trouble is taken to use only magnetic fields.
I've been reading some about the ITER project, tokamaks, and other approaches to plasma containment. Why can't ion trapping approaches such as an orbitrap be used for fusion plasma containment?
I'm pretty sure if there is an imbalance in electron spin that is commonly known as magnetism. In a magnetized piece of iron each atom has it's electrons unbalanced in the same direction. In a nonmagnetized piece, they are all unbalanced, but it's different for each atom. Magnetism is caused...
Ions and Charge
I think you guys may be mislead with the whole charge thing. pH is the negative log of the hydrogen (or technically hydronium) ion concentration. pH + pOH always equals 14 so in a neutral solution, both concentrations equal 10^-7. But the pH is varied by dissolving other...
Battery types
In case you were wondering, 1.2 V rechargeable batteries are usually either nickel-cadmium (cadmium and nickel oxyhydroxide electrodes) or nickel-metal hydride (some alloy usually with a rare-earth metal and nickel oxyhydroxide electrodes). 1.5 V cells are called alkaline because...
I've got some rather simple questions concerning thermistors. First, in viewing spec. sheets I only see one resistance value. What is that value telling me? In some of the specs there is something called a b-constant. What is that? Does a temperature actuated circuit demand an amplifier to...
