Following two, extremely successful, IOP sponsored Geant4 half-day meetings, a third in this series will be held on 16th December 2015 at the Christie Hospital, Manchester.  The focus of the meeting will be applied nuclear and medical physics.  The aim of the meeting is to bring together scientists from a variety of research backgrounds that use Geant4 for medical applications, in particular, in the fields of hadron therapy and radiotherapy.  The meeting will try to identify how the framework is being used, what are the major issues and challenges and how these can be addressed.  The meeting will also serve to showcase completed and currently ongoing simulation projects to highlight any synergies that can be exploited in future applications.  

Thank you to everyone that presented and attended.  Some of the presentations can now be seen below (the rest to come).
