中国散裂中子源 / China Spallation Neutron Source

The China Spallation Neutron Source appears in EP248 在高原与地下，探寻中国“大科学项目” as the Dongguan large-science facility case. [[MiaoQian|苗千]] discusses it alongside cleanroom work at the Dongguan branch of the Institute of High Energy Physics.

In the source, the facility’s explanatory value is that neutron beams can nondestructively probe light elements inside materials. The episode uses lithium batteries as an example: neutron scattering can help researchers observe what happens inside batteries while they charge or operate.

The Dongguan material also links [[BigScienceTechnologySpillover|technology spillover]] back to [[AliPrimordialGravitationalWaveObservatory|阿里原初引力波探测站]]. The source says devices being processed in the Dongguan cleanroom are planned for a detector upgrade that could raise the Ali station’s detector count and precision, making large scientific infrastructure part of a wider instrumentation and [[SemiconductorSupplyChain|semiconductor]] capability story.
