Document #:

LIGO-T1600104-v3

Document type:

T - Technical notes

Abstract:

This report summarizes the result of the UV absorption capabilities measurement of coating samples for the chevron baffle.

The attached document / information is being prepared for publication, in the mean time you will need this key to fully interpret attached data: -
KEY
1) BB = bead blasted
2) Undisclosed #3 = magic black (Acktar)
3) Undisclosed #4 = fractal black (Acktar)
4) Structural coating = laser black (Epner)

v1 - CIT measurement at 200 – 800 nm and planning higher energy measurements
v2 - use to be a public version of v1
v3 - high energy measurement at ALS Berkley
