In 2008, new seismic isolation systems were installed in the two 4 km LIGO
gravitational wave detectors. These systems are prototypes for Advanced LIGO;
a collection of interferometer upgrades which will greatly improve its sensitivity
to astrophysical events. We present the measured performance of the prototype
isolation systems. We compare this to the current Advanced LIGO requirements
and discuss potential improvements which may allow even better performance
in the future.
