ITM characteristic summary

Document #:

LIGO-T1700149-v6

Document type:

T - Technical notes

Abstract:

For purpose of discussion
Since replacement of ITM03 due to excess absorption, all spare ITMs have been scanned using a "gentle absorption" technique. There were no permanent absorbers found.
LIGO Test Data are located as follows:
ITM01 E1000764
ITM05 E1000768
ITM06 E1000769 - Ears already bonded
ITM07 E1000770 - installed at H1x
ITM09 E1000772
ITM10 E1000773

LMA final report
ITM01 C1103254
ITM05 C1103259
ITM06 C1103260 - Ears already bonded
ITM07 C1103261 - installed at H1x
ITM09 C1103263
ITM10 C1103264

We want to match the optic at H1-y
ITM11 E1000774
