Induced fission tracks have been imaged in fluorapatite with a JEOL JEM-2000FX analytical transmission electron microscope that is equipped with a cold stage and anticontamination device. Near the atomic level, fission tracks are not perfectly linear, continuous features but are composed of segments of extended damage that are separated by gaps of undamaged microstructure. Track width is crystallographically controlled. The annealing of induced fission tracks in fluorapatite in the microscope is dependent on the current density of the specimen and the temperature of the specimen. The rate at which individual tracks anneal is variable and may reflect differences in track orientation, grain composition, and degree of initial partial annealing. -from Authors
