Improvements in the CR39 polymer for the macro experiment at the Gran Sasso Laboratory Academic Article uri icon


  • We discuss the preparation of different samples of the CR39 polymer and a number of tests performed with high energy heavy ions. The quality and reproducibility of the manufactured CR39 is discussed as well as the implications for a large area detector (MACRO) used for a search for cosmic magnetic monopoles. © 1991.
