So I've been researching Dense Plasma Focus devices for a while now and a question just occurred to me. Since the fill gass such as deuterium is being ionized and then compressed and fused in the Plasmoid, wouldn't some of the cathode material also be ionized and the trapped in the Plasmoid polluting it? If this is the case what equations would you use to calculate the number of cathod material atoms trapped in the Plasmoid in moles?

See Dense Plasma Focus (http://en.m.wikipedia.org/wiki/Dense_plasma_focus)

I'm sorry you are not generating any responses at the moment. Is there any additional information you can share with us? Any new findings?
 
Ahh don't worry I got my question answered on another thread. The answer is yes the particles to contaminat the Plasmoid now I am trying to figure out how to calculate how many.
 

Thread 'Toponium Discovered'

Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...

Thread 'Dirac-Delta from Normalization of Continuous Eigenfunctions'

I'm following this paper by Kitaev on SL(2,R) representations and I'm having a problem in the normalization of the continuous eigenfunctions (eqs. (67)-(70)), which satisfy \langle f_s | f_{s'} \rangle = \int_{0}^{1} \frac{2}{(1-u)^2} f_s(u)^* f_{s'}(u) \, du. \tag{67} The singular contribution of the integral arises at the endpoint u=1 of the integral, and in the limit u \to 1, the function f_s(u) takes on the form f_s(u) \approx a_s (1-u)^{1/2 + i s} + a_s^* (1-u)^{1/2 - i s}. \tag{70}...
