论文摘要
位移传感器在重力波检测器中具有多种应用。 Ligo Core光学器件的地震隔离链利用光学阴影传感器进行稳定。未来的升级（例如Ligo Voyager）计划在低温温度下运行以降低其热噪声，并需要低温位移传感器。我们介绍了嵌入伯明翰光学传感器和电磁电动机（BOSEMS）的阴影传感器的模拟结果和实验测试的结果。我们确定这些设备可以可靠地在100 k处运行。我们还表明，在低温温度下，BOSEM传感器的性能会提高。
Displacement sensors have a variety of applications within gravitational wave detectors. The seismic isolation chain of the LIGO core optics utilises optical shadow sensors for their stabilisation. Future upgrades, such as LIGO Voyager, plan to operate at cryogenic temperatures to reduce their thermal noise and will require cryogenic displacement sensors. We present the results of simulations and experimental tests of the shadow sensors embedded in the Birmingham Optical Sensors and Electromagnetic Motors (BOSEMs). We determine that the devices can reliably viability operate at 100 K. We also show that the performance of the BOSEM sensors improves at cryogenic temperatures.
