A tracking system for cancelling turbulence-induced beam wander has been operated and preliminary results are reported for mean irradiance and irradiance-fading on target. The experimental program now underway on wander- cancellation and finite-beam effects is described in detail. New instrumental developments for the investigation of turbulence intermittency and its propagation effects are described, including a multiplexed field array of microthermal sensors for modeling the turbulence. The experimental program and new aspects of statistical data interpretation are discussed, with preliminary examples.
