aLIGO IAS WBSC2 Alignment Solutions

Document #:

LIGO-E1200798-v2

Document type:

E - Engineering documents

Abstract:

This notebook calculates/provides the positions and orientations of the IAS theodolite-total-station/autocolimator for initial alignment and positioning of the optical elements in the WBSC2 chamber. It also calculates the pitch angles of the WBSC2 optics relative to the local horizontal. The alignment solutions (angles, positions/distances) calculated in this notebook are inserted into the IAS WBSC2 alignment procedure. This document is not the WBSC2 alignment procedure, but provides notes and values used to create the procedure.
