Liquid hydrogen cooling could be some intermediate solution between helium and liquid nitrogen based cooling. For example, some type of superconductors could be cooled by liquid H2, and this could be much cheaper than the liquid He. What are their…

I've been working with SC magnet quench simulations. The conductor is made from NbTi in a Cu channel with a 5:1 ratio of Cu:NbTi. Opera3d has a quench program with an example that I began working from. In a quench scenario using a solenoid made from…

Consider the Robin boundary condition for the diffusion/heat equation $\mathrm{u_t=a(t)u_{xx}+f(x,t)}$: $$\mathrm{-k(t)u_x(0,t)=h(t)u(0,t)}$$ or $$\mathrm{u_x(0,t)+\frac{h(t)}{k(t)}u(0,t)=0}$$ where $\mathrm{k(t)}$ thermal conductivity and…

Basically, I want to know whether it’s the size of the permanent magnet, a.k.a. the strength of the permanent magnets, magnetic field, or the super conductor that decides how fast it will spin whether it’s going to spin faster or slower. Currently…
