Bicep Array is a cosmic microwave background (CMB) polarization experiment that will begin observations from the Amundsen-Scott South Pole Station in early 2020. As the next stage of the Bicep/Keck series of experiments, Bicep Array will replace the five receivers of the Keck Array with four much larger receivers. This page details the activities of the group at the University of Minnesota in the year leading up to deployment of the experiment, including the assembly of the new telescope mount at UMN and the integration of the drive system, controllers, and receivers.

- 3 – Axis Motion - With successful integration of the Theta motors, we quickly moved into installing the elevation motors. Installation itself was relatively simple, and since we’d already laid the groundwork with our control software we were able to get it up and running in only an hour or so. Once running, we needed to check that the limit […]
- Second Axis Rotation - Although we were able to get Azimuthal rotation under computer control two weeks ago, we weren’t quite ready to jump right into attaching the motors of the other axes. Instead, we spent the last two weeks digging into the controller software and ensuring that we could get the mount to move in a smooth and […]
