Dataset for Explanation of core ion cyclotron emission from beam-ion heated plasmas in ASDEX Upgrade by the magnetoacoustic cyclotron instability

Based on the fast ion distribution function obtained from the TRANSP/NUBEAM code, together with a linear analytical theory of the magnetoacoustic cyclotron instability (MCI), the growth rates of MCI could be calculated.

The data to prove that the excitation mechanism of core ICE driven by sub-Alfv´enic beam ions in ASDEX Upgrade is MCI as the time evolution of MCI growth rates is broadly consistent with measured ICE amplitudes had been updated. The datasets record: 1. MCI instability in different propagation angles; 2.
