Interaction of the ESD with electrical charges of the test masses in Advanced LIGO

Document #:
Document type:
G - Presentations (eg Graphics)
Other Versions:
Charging or redistribution of electrical charge on the LIGO mirrors could change the force applied by the electrostatic drive (ESD). It results in changing of the actuation coefficient of the ESD and additional fluctuating force acting on the test masses. In this document we discuss the forces acting on the test mass from the ESD and the results of the charge measurements of the Advanced LIGO test masses.
