Graphite Ablation Experiments in the LHMEL Laser Facility

This work proposes that there are still reasons to understand the ablation processes of carbon even when under equilibrium conditions. Due to these uncertainties, initial testing was conducted in AFRL/RX's LHMEL laser facility. Spectral measurements of the ablating gas were taken for surface temperatures upto 4000K. From the measurements, the presence of C2 and C3 carbon gases are confirmed. For high heating rate conditions, the formation of CN was also measured.
