Research Abstract

One component plasma which is confined in an ion trap can be cooled to near the absolute zero temperature by the Doppler laser cooling method. This proposal aims to clarify experimentally the effect of Coulomb interaction on the character of extremely low temperature plasma. We have established a nondestructive laser induced fluorescent measurement technique for the cooled plasma. The shape of the spectra which are observed by using the technique shows unusual change during the cooling process from room temperature to extremely low temperature.
