Description
The IR7 insertion of the Large Hadron Collider (LHC) is dedicated to
beam cleaning with the design goals of absorbing part of the primary
beam halo and of the secondary radiation. The tertiary halo which
escapes the collimation system may heat the cold magnets at
unacceptable levels, if no absorber is used. In order to assess the
energy deposition in the sensitive components, extensive simulations
were performed with the intranuclear cascade code FLUKA. The straight
section and the dispresion suppressors of IR7 were fully implemented.
A modular approach in the geometry definition and an extensive use of
user-written programs allowed the implementation of all magnets and
collimators with high precision, including flanges, steel supports
and magnetic field. The talk will be focused on the number and
location of additional absorbers needed to keep the energy deposition
in the coils of the magnets below the quenching limit.
