TOBA: Torsion-Bar Gravitational-Wave Antenna |
|
Abstract |
TOBA (TOrsion Bar Antenna) is a mid.-frequency gravitational wave anttenna, formed by two bar-shaped test masses and laser-interferometric sensors to monitor their differential angular fluctuations. This antenna has a fundamental sensitivity to signals below 1 Hz, even with a ground-based configuration. We have developed prototype detectors scince 2010, and now are prepareing for the third version of the protptype, with 40-cm scale mass and cryogenic operation. We will show the current status and prospects in this presentation. |
