Description
Speedmeters are becoming interesting for third generation gravitational wave detectors. Here we compare a new kind of sloshing-Sagnac interferometer with the ring-Sagnac interferometer. The sloshing-Sagnac requires only linear cavities and has alternating resonant and anti-resonant cavities, which act as a type of Khalili-cavities. These have the potential advantage of allowing a reduction of the coating thermal noise. Here we evaluate the quantum noise limited sensitivity and the coating noise reduction compared to a conventional position-meter (such as Advanced LIGO).
