Article Synopsis
- This study presents a new cold atom source for strontium (Sr) that uses a two-dimensional magneto-optical trap (MOT) directly connected to an atom dispenser.
- The researchers measure the atom flux and achieve loading rates of up to 10 atoms per second in a three-dimensional MOT.
- The design is compact, simple to build, and energy-efficient, making it a significant advancement for applications in optical atomic clocks, quantum simulations, and ultracold Sr-based computing technologies.
Coherence time is one of the fundamental characteristics of light sources. Methods based on autocorrelation have been widely applied from optical domain to soft X-rays to characterize the radiation coherence time. However, for the hard X-ray regime, due to the lack of proper mirrors, it is extremely difficult to implement such autocorrelation scheme.

Conventional optical methods, based on autocorrelation, are very difficult to realize due to the lack of mirrors. Here, we experimentally demonstrate a novel method which yields a coherence time of 174.
