Abstract
This paper presents background measurements performed during special runs with high β* optics at injection energy using ALFA detectors in the ATLAS experiment at the LHC. Such special runs require specific collimation scheme which reduces beam-induced background. Hence, complex preparation including simulations and tests had to be performed. This document discusses results of tests with different collimation schemes and background measurement during final data taking. In particular one of the runs was devoted to test a new type of collimators based on crystal channeling effect, that were used during physics data taking for the first time at the LHC.
