  1. 2. Development of a highly sensitive, multi-channel suspension point interferometer
    Bram Slagmolen (The Australian National University)

    Low Frequency Sensing and Control
    Presentation

    Inter-platform motion in the seismic frequency range presents a challenge for both current and future generation detectors. Reduction of this movement requires displacement sensing over 3 degrees-of-freedom between each pair of isolation platforms, and the stabilisation outcome is dependent on the sensor performance.

    At ANU, we are prototyping a multi-channel, optical displacement sensor....

  2. 37. Progress towards a 6 DoF inertial sensor: commisioning and application in semi-classical gravity measurements
    Jiri Smetana (University of Birmingham)

    Low Frequency Sensing and Control
    Presentation

    We present further progress on our six-degree-of-freedom (6D) inertial sensor. Our purpose is to improve on the low-frequency seismic noise sensing of the current aLIGO detectors with a device that is capable of simultaneously reading out all six degrees of freedom and decoupling the troublesome cross couplings, such as tilt-longitude that affect commercial seismometers. We have reached the...

  5. 132. Heavy suspension designs for LIGO A#
    Brian Lantz (Stanford Univ.)
    23/05/2023, 12:00
    Low Frequency Modeling, AI use
    Presentation

    LIGO A# is an upgrade path for the LIGO facilities which has recently been recommended (LIGO-T2200287). This upgrade is suggested after the completion of O5. A major part of the upgrade is to replace the optics with 100 kg mirrors on new suspensions. The new suspensions are based on the design history of the Advanced LIGO and GEO suspensions, and incorporate lessons learned from the operation...

  6. 66. Compact low-frequency optomechanical accelerometers for GW detectors
    Felipe Guzman (Texas A&M University)
    Low Frequency Sensing and Control
    Presentation

    We will report our progress on the development of our compact low-frequency optomechanical accelerometers, which consist of monolithically fabricated mechanical resonators that are read out by miniaturized heterodyne laser interferometers. The resonators are made of fused-silica, with a test mass of approximately 2.5 grams and a mechanical quality factor of 4.77x10$^5$ at 4.7 Hz.
    We have...
