SUSPENSIONS

INTRODUCTION

This web site is for posting useful documents related to the Advanced LIGO Suspensions.
The documents are for LIGO internal use only. It is hosted by Calum I. Torrie.

The Triple Pendulum Controls Protoype Suspensions have been built and developed by Scientists and Engineers from
LIGO Laboratory, California Institue of Technology,
Institue for Gravitaional Research at the University of Glasgow GEO 600 Group,

Norna Robertson at the Edward L Ginzton Laboratory Stanford University
with input from staff at the University of Hannover GEO 600 Group.

For the Quadruple Pendulum Controls Prototypes for the LASTI experiment at MIT the UK effort expands
to include Rutherford Appleton Laboratory / Birmingham University / Cardiff University / Strathclyde University.

 


SUMMARY
  Advanced LIGO will incorporate 23 triple and 30 quadruple pendulum suspensions.
  These are based on the design used for the GEO triple pendulums.
     

  PRELIMINARY DESIGN
    2 controls prototype triple pendulums and 1 quadruple prototype pendulum have been delivered to MIT as part of the LASTI project.
