OBSOLETE: aLIGO PRM and SRM TIlt Angles

Document #:

LIGO-E1100688-v1

Document type:

E - Engineering documents

Abstract:

This document presents an analysis of the local hanging angles for the PRM and SRM mirrors in aLIGO interferometers, H1, L1, H2. The hanging angles are based on local slopes for the corner stations at LLO and LHO, as described in T080258-00. They are further based on the ITM wedge angle of 0.076, thick side down.

Notes and Changes:

THIS DOCUMENT IS HEREBY MADE OBSOLETE. THERE SHOULD NOT BE ANY FURTHER REVISIONS TO THIS DOCUMENT. SEE T080258 INSTEAD.
A paper copy of document E1100688-V1 (mislabeled as T1100688-v1) had a limited distribution around 21 July 2011, but was never uploaded to the DCC. Since then document T080258 was issued covering the tilt angles of all core optics including PRM and SRM. The newer document makes this document obsolete.
