WebMar 16, 2024 · The levitated sensor detector (LSD) is a compact resonant gravitational-wave (GW) detector based on optically trapped dielectric particles that is under construction. The LSD sensitivity has more favorable frequency scaling at high frequencies compared to laser interferometer detectors such as LIGO and VIRGO. WebA key feature of levitated optomechanical systems is their ability to evade thermal noise from direct contact with the environment—which is always present in clamped oscillators—simply by operating at ultra-high vacuum, but while the vacuum chamber walls remain at room temperature. crystal bubbly hookah cleaner
