Third generation Infrastructures
- Kevin Kuns
In the run-up to LIGO's O4 commencement, some new Parametric Instability (PI) challenges have cropped up. Whilst LIGO has infrastructure to deal with PI, the best method still proves to be thermally tuning these instabilities out, with active damping being a risky endeavor. Despite the chances of facing compounding PI problems on the path to O5 being high at LIGO, the issue is still expected...
Optomechanical designs for third-generation gravitational-wave detectors are currently under development. The input optics for 3G detectors will be a major consideration for the infrastructure and facilities costs. In this talk we will discuss the requirements for input optics for Cosmic Explorer, and consider some optical designs which satisfy those requirements with minimal facilities costs.
The 3rd generation instrument era is approaching, and the Einstein Telescope giant Laboratory is becoming a reality with the possibility to install a detector for Gravitational Waves observations in an underground site where seismic noise is 100 times smaller than on the surface. Moreover, new available technologies and the experience acquired in operating advanced detectors are crucial points...
The sensitivity of current gravitational wave detector (GWD) such as advanced LIGO is partially limited by thermal noise arising from amorphous silica and titania-doped tantala coatings at their most sensitive frequency band. Future GWDs are planned to employ low thermal noise coatings so that one can explore further into the Universe with improved sensitivity. Crystalline AlGaAs coatings are...
update on the Voyager upgrade of LIGO
As part of the design of the Einstein Telescope (ET) gravitational wave detector, a thorough study of the scattered light and its impact in the sensitivity must be performed to ensure that is not going to compromise the experiment. We present the first estimation of the sources of scattered light inside the main arms of ET for both high- and low-frequency interferometers and propose a baffle...
