A Passive UV-Based System for Discharging the Test Masses of Ground Based Gravitational Wave Detectors
Saps Buchman, Suwen Wang, Shallendar Saraf
We present a passive ultraviolet charge management system for the fused silica test masses in ground-based laser interferometric gravitational wave detectors. The system uses photo…
Flight and ground demonstration of reproducibility and stability of photoelectric properties for passive charge management using LEDs
S. Buchman, T. S. M. Al Saud, A. Alfauwaz +7
Charges as small as 1 pC degrade the performance of high precision inertial reference instruments when accumulated on their test masses (TMs). Non-contact charge management systems…
Two Approaches for the Passive Charge Management of Contactless Test Masses
S. Wang, S. Saraf, J. Lipa +2
Free floating Test Masses (TM) of inertial reference instruments accumulate charge mainly through the triboelectric effect during separation from their housings and, if in the spac…
Differential optical shadow sensor for sub-nanometer displacement measurement and its application to drag-free satellites
Andreas Zoellner, Si Tan, Shailendhar Saraf +4
We present a method for 3D sub-nanometer displacement measurement using a set of differential optical shadow sensor. It is based on using pairs of collimated beams on opposite side…
Ground Testing and Flight Demonstration of Charge Management of Insulated Test Masses Using UV LED Electron Photoemission
Shailendhar Saraf, Sasha Buchman, Karthik Balakrishnan +15
The UV LED mission demonstrates the precise control of the potential of electrically isolated test masses that is essential for the operation of space accelerometers and drag free…
The Design of a Drag-Free CubeSat and the Housing for its Gravitational Reference Sensor
Carlo Zanoni, Abdul Alfauwaz, Ahmad Aljadaan +11
A Drag-Free CubeSat mission has been proposed to demonstrate the feasibility of a Gravitational Reference Sensor (GRS) with an optical readout for a 3 units (3U) spacecraft. A pure…
