Article Synopsis
- The new calibration system for cosmic microwave background (CMB) polarization uses a sparse wire grid to reflect polarized light, improving accuracy in measurements.
- A remote-controlled feature allows for regular calibration, which was previously not possible, utilizing electric actuators to adjust the wire grid's position.
- The system includes a motor for rotation and sensors to ensure precise monitoring, resulting in minimal systematic errors and planned installation in telescopes at Simons Observatory.
