Part of the Basic Life Sciences book series (BLSC, volume 63)


A code set is described for simulating positive ion tracks in a variety of media and having the capability of interfacing with several secondary electron transport codes. The set derives out of the MOCA series of simulations and is motivated primarily by a perceived need for easier code maintenance (updating), documentation, and verification.

Cluster analysis of stochastic track structures is introduced as a quantifiable method to distinguish effects of different physical models and assumptions. The concept of distance distributions is generalized by extending the idea beyond pairs of individual interactions to pairs of clusters of interactions.
