Simons Observatory

The Simons Observatory (SO) is a newly funded facility which will be built at an elevation of 5,200 meters in the Atacama Desert in Chile. SO combines existing efforts (namely the POLARBEAR (PB) and Atacama Cosmology Telescope (ACT) collaborations) to build a groundbreaking set of telescopes to observe the Cosmic Microwave Background (CMB). SO will explore the history and evolution of our universe and push our existing technologies towards CMB-S4. The project was made possible by awards from Simons Foundation and Heising-Simons Foundation, and involves over 30 institutions across the globe working together to set the stage for the next generation of CMB experiments.

My work for SO mainly involves detector testing and cryogenics design. I am motivating our magnetic shielding requirements by measuring the magnetic sensitivity of existing transition edge sensor (TES) bolometers and superconducting quantum interference devices (SQUIDs) (E.M. Vavagiakis, S.W. Henderson, K. Zheng et al., Magnetic Sensitivity of AlMn TESes and Shielding Considerations for Next-Generation CMB Surveys, JLTP 2018). I am also involved in the design of SO’s large cryogenic receiver. Finally, I’m working to promote education and public outreach for SO, taking part in social media and outreach initiatives for the collaboration.
