Large Aspect Ratio Tearing Mode Benchmark

• circular plasma
• eta is constant over the whole computational domain
• no visco
• density constant $7.24\cdot10^{19}m^{-3}$ (deuterium)
• For JOREK normalization:
  • $\rho_0=n_0\cdot m_D=7.24\cdot10^{19}m^{-3}\cdot3.34\cdot10^{-27}kg=2.42\cdot10^{-7}kg\,m^{-3}$
  • $\sqrt{\mu_0\rho_0}=5.5\cdot10^{-7}$
  • $\sqrt{\mu_0/\rho_0}=2.3$
