Beam simulation model
• Simulation starts at HG-WUP using beam
parameters from MERIT Data Analysis(latest update :
07Oct08), including dispersion term.
• If there is vacuum only between WUP and
center of target horizontal and vertical beam
parameters very close to Ilias results. Real MC
provides slightly larger sigmas due to interaction
with beam windows and air.

How energy deposition depends on beam parameters?
Three beam setup scenarios:
Only vertical&horizontal
divergence. Ilias sigmas at
target center.
Vertical&horizontal and
angular divergences. Ilias
parameters at HG-WUP.
Same as 2 plus 3 mrad
horizontal beam tilt
Maximum of energy deposition
density has weak dependence
on angular beam distribution
