Abstract:

The Global Inverted Pendulum Control was implemented in Virgo and maintained in V+. In was introduced in order to get rid of background noise contaminating the sensors involved in Inverted Pendulum control. The technique enhanced the duty cycle of the interferometer. Also in AdV such a technique will be used. In this brief report the principle and the initial tests with the new system are commented.
