Re-assessing HAM-ISI Noise Budget Performance Model for aLIGO

Document #:

LIGO-T1300645-v5

Document type:

T - Technical notes

Abstract:

With the addition of HEPI, as well as a few extra control paths which are possible from the addition of Stage 0 L4Cs, it is necessary to re-calculate the performance of the platform for noise-budgeting techniques originally developed in eLIGO. This document describes the details of this recalculation.
