@inproceedings{Crilly2022ConstraintsOI, title={Constraints on Ion Velocity Distributions from Fusion Product Spectroscopy}, author={Aidan Crilly and B. Appelbe and O. M. Mannion and William T. Taitano and E. Hartouni and A. S. Moore and Maria Gatu-Johnson and Jeremy Chittenden}, year={2022} }

Recent inertial conﬁnement fusion experiments have shown primary fusion spectral moments which are incompatible with a Maxwellian velocity distribution description. These results show that an ion kinetic description of the reacting ions is necessary. We develop a theoretical classiﬁcation of non-Maxwellian ion velocity distributions using the spectral moments. At the mesoscopic level, a monoenergetic decomposition of the velocity distribution reveals there are constraints on the space of…
