Ionisation and recombination rate coefficients of H and He. The coefficients, valid at n e = 1020 m−3, are extracted from the ADAS database26. Molecular assisted rate (MAR) coefficients were obtained from ref. 27. The shaded region on the right highlights T e values of a H and He plasma where ionisation is the dominant process. The grey box on the left indicates a recombination dominated temperature regime
