Energy deposition and machine­detector<br />

interface<br />

Was not a problem in the early years<br />

With more beam energy/intensity and superconducting magnets particle losses<br />

due to scattering, collimation system per<strong>for</strong>mance etc. become more critical<br />

Similar type of calculations as with HEP detectors (showers), but need to link it<br />

with beam dynamics in the machine<br />

Interfacing Monte­Carlo radiation transport (FLUKA, GEANT4, MCNP, MARS) to<br />

<strong>accelerator</strong> tracking<br />

Examples: STRUCT/MARS at FNAL; FLUKA/SIXTRACK <strong>for</strong> LHC; BDSIM<br />

(standalone GEANT4 based tracking <strong>for</strong> ILC and ATF2)
