Description
The LSC plans on upgrading the current LIGO detectors to a detector known as A♯ after the conclusion of the fifth observing run. A♯ includes an increase of the test mass mass to 100 kg, 10 dB of frequency dependent squeezing, an increase in the arm power to 1.5 MW, redesigned suspensions, a reduction in the coating Brownian noise by a factor of two, improved seismic isolation, and suppression of Newtonian noise from Rayleigh waves. All of the upgrades planned for A♯ are required R&D efforts for Cosmic Explorer.
