LIGO Document T970212-v1
- Calculation of the transient thermoelastic response of a high relectance mirror in an optical cavity used for material contamination measurements.
The Optical Contamination Facility (formerly the OTF, Optical Test Facility) consists of 3 vacuum chambers with high-finesse, resonant optical cavities used to test the effect of outgassing from materials/assemblies on optical properties (absorption, scatter @1064nm) over time.
basic description: P990032
original block diagram: D1001800
new block diagram: D1800215
compendium of all materials/assemblies tested to date (includes RGA results as well): E1000193
- New calculations of the high reflectance transient surface temperature, and thermally induced deflection, for the mirrors used in the optical contamination facility/cavity using Ansys and an analytical model (for 1 watt absorbed power).
