Abstract
Between 104 and 10u6 A9Be^+ ions were trapped in a Penning trap and laser-cooled to siml K, where they formed a crystalline plasma. We measured the ion temperature as a function of time after turning off the laser-cooling and observed a rapid temperature increase as the plasma undergoes the solid-liquid phase transition at T=10-mK Gamma sim). We present evidence that this rapid heating is due to a sudden release of energy from weakly cooled degrees of freedom involving the cyclotron motion of trapped impurity ions.
