An in-situ observation system was developed to record time-lapse images of etch pits formed on the surface of a solid-state nuclear track detector (SSNTD); CR-39. The CR-39 track detector was irradiated with alpha and Li particles produced by a neutron capture reaction; 10B(n; α)7Li. The time-lapse images of the etched surface of the detector were carefully observed to elucidate the etch pit formation process. Pit-evolution images were constructed by digital image processing of the data of the time-lapse images. In addition; a finite element model of SSNTD was used to simulate the etch pit formation. Pit-evolution image analysis and computational simulation were performed to reveal the etch pit formation obtained via the incidence angle of energetic particles on a CR-39. © 2008 The Japan Society of Applied Physics;
