ELECTROMAGNETIC WORKING GROUP 
                    plan for 2006 


  1) Validation and verification of EM physics as a first priority:
       - extension, systematization and atomization of the validation suite;
       - introducing histogram comparisons in the suite;
       - providing test for current XTR models against test beam data;
       - providing test for synchrotron radiation process;
       - providing web page for verification results.
       
  2) Publications related to the Urban's model of Multiple Scattering.     

  3) Further update of ionization processes:
       - spin and mass effects for pions, muons, kaons;
       - tuning and verification of corrections for hadron and ion ionization;
       - provide a possibility to plug in user data for stopping powers;
       - improve the kinematics of final state sampling of PAI models.

  4) Develop a process of the elastic Coulomb scattering

  5) Provide alternative msc processes for different particle types: 
     e+,e-, muons, hadrons, and ions.
 
  6) Review of the bremsstrahlung models including LPM effect.
 
  7) Extend e+ annihilation to hadrons : add 3pi and K+K- production.

  8) Introduce K-L shell X-rays in the photoElectric process.

  9) Optical processes updates:
     - micro Facet Extension : 
       - introduce virtual base class BoundaryMicrofacetModel;
       - include new LIP (Lisboa) micro facet model;
     - unified model extension :
       - allow a specular as well as diffuse component for the 
         transmitted photon;
     - Fresnel Lens (LIP Lisboa) as a new advanced example;
     - attached Surfaces (the aim is succinctly model the optical transport
       in volumes with different optical treatments on different sides/faces);
     - extend the usage of optical processes to G4Boolean Solids
