openmc.stats.Muir

class openmc.stats.Muir(e0=14080000.0, m_rat=5.0, kt=20000.0)[source]

Muir energy spectrum.

The Muir energy spectrum is a Gaussian spectrum, but for convenience reasons allows the user 3 parameters to define the distribution, e0 the mean energy of particles, the mass of reactants m_rat, and the ion temperature kt.

Parameters:
  • e0 (float) – Mean of the Muir distribution in units of eV
  • m_rat (float) – Ratio of the sum of the masses of the reaction inputs to an AMU
  • kt (float) – Ion temperature for the Muir distribution in units of eV
Variables:
  • e0 (float) – Mean of the Muir distribution in units of eV
  • m_rat (float) – Ratio of the sum of the masses of the reaction inputs to an AMU
  • kt (float) – Ion temperature for the Muir distribution in units of eV
