  1. 98. A dual tunnel configuration for the Einstein Telescope

    Presentation

    We present a dual-tunnel architecture as an alternative to large cavern halls. It comprises raise-bore wells and an upper service tunnel. By anchoring the heads of the seismic attenuation chains directly to bedrock the seismic motion amplification of tall towers is eliminated and the area around the optical components decluttered. Individual access can be provided to all seismic attenuation...

  2. 113. Laser noise requirements for the Einstein Telescope

    Presentation

    Laser noise can be modelled as laser amplitude and/or phase modulation sidebands that enter the interferometer. In an ideal dark-fringe condition, they interfere destructively at the dark port. But in reality, asymmetries between the two interferometer arms result into these laser noise sidebands competing against the gravitational wave phase modulation sidebands at the interferometer readout...

    Presentation

    The Photon calibrator (Pcal) is the system utilized to provide an absolute calibration for the advanced LIGO detectors. Fundamentally, the system injects a secondary laser source into the interferometer End Test Mass (ETM). Measurement of this external laser yields a reference of the ETM motion. Historically, the Pcal measures the light reflected by the ETM on the receiver (Rx) power...

  4. 131. The Residual Amplitude Modulation Stabilization in Virgo

    Presentation

    The impact on Virgo Sensitivity of the unwanted amplitude modulation of the Virgo Laser beam introduced as a collateral effect of its phase modulation, required by the adoption of the Pound-Drever-Hall technique, has been estimated at the end of O3 in preparation for the next Science Run. Its contribution turned out to be significative, reducing up to one third the target Sensitivity. That...

  5. 15. GWexpy: GWpy Expansions for Experiments
    Tatsuki Washimi
    22/05/2026, 17:12
    Other
    Presentation

    GWexpy is an extension package fully compatible with GWpy, developed to support detector characterization, commissioning, and experimental R&D in gravitational-wave instrumentation. Rather than replacing established GWpy workflows, it extends them toward analysis tasks that frequently arise in real detector environments: batch handling of large auxiliary-channel sets, multi-channel correlation...
