The INTENTAS project aims to demonstrate sensitivity gains using squeezed Bose-Einstein condensates in microgravity. Set to operate in the Einstein-Elevator in Hannover, it will deploy rubidium (Rb) atoms to show that measurements below the Standard Quantum Limit (SQL) can be achieved under challenging conditions.
Detecting at or below the SQL imposes strict requirements on the detection system, particularly in terms of quantum efficiency and the reduction and rejection of stray light. This contribution will outline the design of the detection system for the INTENTAS project, presenting initial characterizations and results.
