// This is the *BASIC* version of Hadrontherapy, a Geant4-based application
// See more at: http://g4advancedexamples.lngs.infn.it/Examples/hadrontherapy
//
// Visit the Hadrontherapy web site (http://www.lns.infn.it/link/Hadrontherapy) to request 
// the *COMPLETE* version of this program, together with its documentation;
// Hadrontherapy (both basic and full version) are supported by the Italian INFN
// Institute in the framework of the MC-INFN Group
//
//
// Hadrontherapy Users are recommended to use the prepared macro files in order to activate the 
// most appropriate physics for hadrontherapy applications.
// As one can easily see the physics we suggest is contained in the
// 'QGSP_BIC_EMY' list adding to the decay processes (activated as default).
//
//
//    ******                     SUGGESTED PHYSICS                 *********
//
//    AT MOMENT, IF ACCURATE RESULTS ARE NEEDED, WE STRONGLY RECOMMEND: 
//    1. The use of the macro 'hadron_therapy.mac', that is connected with the HadrontherapyPhysicsList.cc file.
//    2. the QGSP_BIC_EMY Reference Physics Lists (define the PHYSLIST eviroment variable):
//       export PHYSLIST=QGSP_BIC_EMY
//       User must considered that, in this second case, radioactive processes are not activated
