On-Ground Testing of Dual-Sided Release Mechanism of TianQin Test Mass Using a Pendulum

On-Ground Testing of Dual-Sided Release Mechanism of TianQin Test Mass Using a Pendulum

The high-precision gravitational reference sensor, which hosts a heavy test mass (TM) surrounded by electrodes with a relatively large gap, is crucial in all high-sensitivity drag-free sensors. Consequently, a dedicated locking mechanism is needed to securely hold the TM during the launch phase. Aft...
