R and D for co-working condensed and discrete transport methods in Geant4 kernel

Abstract

A R and D project related to the extension of the Geant4 toolkit has been recently launched to address fundamental methods in radiation transport simulation. The project focuses on simulation at different scales in the same experimental environment: this set of problems requires new methods across the current boundaries of condensed-random-walk and discrete schemes. The new developments have been motivated by experimental requirements in various domains, including nanodosimetry, astronomy and detector developments for high energy physics applications. The scope and main research features of the project are presented. The ongoing activity and preliminary results at the time of writing this document are summarized; since the present contribution to the conference proceedings is due two months before the conference, the status and preliminary results outlined in this paper will be superseded by the new developments to be presented at the conference.
