ABSTRACT
We discuss here the development of a Langmuir probe (LP) diagnostic to examine high-density, high-temperature inhomogeneous plasmas such as those that can be created at the University of Rochester's Laboratory for Laser Energetics OMEGA facility. We have configured our diagnostic to examine the velocity of the plasma expanding from the target. We observe velocities of approximately 16-17 cm/µs, with individual LP currents displaying complex structures, perhaps due to the multiple atomic species and ionization states that exist.
