ECR - Reduction of Bias Voltage Noise in OMC DCPDs

Document #:

LIGO-E1600061-v1

Document type:

E - Engineering documents

Abstract:

Changing the value of two of the filter capacitors used in the bias regulator for the ISC Split Whitening Board, D1300520, will lower the voltage noise on the OMC DCPD biases by a factor of 10 at key frequencies.
