ETM Low Voltage Low Noise Electro-Static Driver Main Board

Document #:

LIGO-D1500016-v6

Document type:

D - Drawings

Abstract:

A circuit to permit a lower voltage control of the ESD actuation to supplement the high voltage ESD amplifiers. Provisions are made to incorporate the stray upgrades that are present in the field as well as to provide new functionality as prompted by operational experience running the existing ESD system
