A NOVEL-APPROACH FOR MEASURING THE RADIAL-DISTRIBUTION OF CHARGE IN AHEAVY-ION TRACK

We describe the design and uses of possible semiconductor test structu res for measuring the initial radial distribution of charge and subseq uent charge transport in a high energy, heavy-ion track. Numerical sim ulations show how the test structure can resolve different radial dist ributions of charge within an ion track. The test structure simulation s also show the importance of accurately representing ion track struct ure in single event effects simulations.
