Recorded talks: Beyond Current Detectors: Beyond Current Detectors Talk Index

The LSC has formed a working group to study scenarios for upgrading the LIGO detectors in the 2025-2035 timeframe. While the work of this group has not yet started in earnest, I will introduce the subject and make an invitation for people to give input on this topic at this workshop.
During last spring the Virgo Collaboration began an effort to define the scientific program in the decade ~ 2026-2036, which corresponds to the period between the end of the O5 data taking and a possible first Einstein Telescope data taking. This work encompasses two axes, developed in parallel: identifying the major science questions to which Virgo - in the framework of the LVK network - can...
The R&D activities on the A+ coatings are close to end. The coating recipe has to be confirmed in about 2 months and then it will be the time to optimize the coating deposition on full scale substrates. The legacy of this R&D period is full of new insights about the origin of thermal noise in coatings, less numerous are the insights on the origin of absorption in amorphous materials, but,...
Crystalline mirror coatings of epitaxially-grown GaAs/AlGaAs are a most promising option for LIGO’s Post-O5 upgrade. With extremely low optical losses and a coating thermal noise that is more than 5x lower that Advanced LIGO coatings, these crystalline coatings represent the most significant improvement in coatings research in the past 20 years. The change from amorphous to crystalline...
One of the keys of interferometric gravitational wave detector projects is to make improvement plan for future. In KAGRA collaborations, we discuss the plan of KAGRA+, which is the next step. The white paper was released on August 2019, just after the previous GWADW. I explain the history and conclusion of this white paper briefly.
