Abstract

GRETINA, a quarter-scale version of the proposed Gamma-Ray Energy Tracking Array used to study atomic nuclei, was delivered to Argonne's ATLAS accelerator facility in 2013. Its detector hemispheres are each cantilever-mounted on a manually operated hexapod alignment frame. This presentation covers how fiducials were placed so the hexapod could be aligned directly, and the measurement approach that followed. Presentation slides only; no written abstract is held in the CMS archive.
