Energy Deposition Issues at 8 GeV H-Beam Collimation and Injection to the Fermilab Main Injector

The energy deposition and radiation issues at 8 GeV H
^-
beam collimation in the beam transfer line and at stripping injection to the Fermilab Main Injector (MI) are analyzed. Detailed calculations with the STRUCT [1] and MARS 15 [2] codes are performed on heating of collimators and stripping foils, as well as on accelerator elements radioactivation at normal operation. Extraction of the unstripped part of the beam to the external beam dump and loss of the excited-state H
0
atoms in MI are also studied.
