a Complete process flow, including the trapping and cooling, state selection, Ramsey interrogation, and detection processes. b Specifics of the cooling phase, particularly the power trends of the cooling laser and the repumping laser. c Details of the microwave interrogation process, including a microwave-optical state selection process and a classic Ramsey process. Importantly, CAMiCS would correct the microwave power imbalance induced by free expansion through symmetry control of the two microwave pulses. d Specifics of two probe lasers, traveling wave fields, and repumping lasers in the detection process. e Frequency variation of the cooling laser including pre- and post-cooling and the detuning in the Ramsey process.
