aLIGO, SQZ, Electronics Block Diagram

Document #:

LIGO-E1500362-v7

Document type:

E - Engineering documents

Abstract:

The H1 squeezing experiment employed standard aLIGO electronics and used Beckhoff. The same approach is proposed for the aLIGO squeezer, although we anticipate using Beckoff only for interfacing. The automation of the squeezer will be done within the Guardian infrastructure. Guardian code for locking the VOPO is under development as part of the VOPO R&D effort.

NOTE: ISCT6 and a small 3'x 5' table will be sued for the in-air components - drawings need to be updated
