Protecting installed core optics from particulates

Document #:

LIGO-T080067-v1

Document type:

T - Technical notes

Abstract:

Advanced LIGO optics are vulnerable to particulate contamination in fabrication and
during and after vessel installation, potentially limiting interferometer performance.
Tolerable contamination levels, resulting environmental requirements, and methods for
achieving and maintaining adequate conditions are developed and discussed.

Notes and Changes:

v1 is equivalent to 04.
N.B.: Not for public release as yet -- still too many uncertainties.
