 Hi Ercan,

  you're right. As you have read in the message of Alberto in the FLUKA
  archive, the production of synchrotron radiation is not yet implemented
  in FLUKA: you have to use an external generator to obtain a synchrotron
  radiation spectrum (Alberto reported a routine to do this) and then write
  a source routine, to sample from this spectrum.

  Beyond your particular case, if you want to simulate charged particles in
  a magnetic field you have to:

  - define the magnetic field via the card MGNFIELD;
  - activate the magnetic field tracking in the regions interested by the
    magnetic field in the card ASSIGNMAt.

  The bending radius will follow the Lorentz equation...

  Maybe you can find useful also to use the STEPSIZE card in the regions
  interested by the magnetic field:it allows the setting of a minimum and a
  maximum step size for every region.
