| contents | We demonstrate buffer gas cooling of carbon atoms to cryogenic temperatures. By employing pulsed two-photon excitation followed by vacuum ultraviolet fluorescence detection, we measured the arrival time distribution of the ablated carbon atoms to the detection volume at various helium buffer gas densities. The experimental data, corroborated by Monte Carlo simulations, reveal a rapid decrease in the local temperature of the carbon atom gas to approximately 10~K within tens of microseconds. The findings establish a major step towards novel research utilizing cold and ultracold carbon atoms. |
