Abstract

IsoDAR@Yemilab is a unique facility for underground neutrino physics. The system comprises an accelerator-driven $\bar{\nu}_e$ source located next to the Yemilab LSC 2.3 kt detector. Because this facility is first-of-its-kind, it opens new approaches to Beyond Standard Model (BSM) physics searches. The program is most well-known for its capability to perform searches for new oscillation signatures at high statistics in a model-agnostic manner. IsoDAR@Yemilab can definitively resolve the question of $\bar{\nu}_e$ disappearance at short baselines. Beyond this, IsoDAR offers a broad range of searches for new neutrino properties and new particles. The facility uses a state-of-the art cyclotron, that is now fully designed and is undergoing protoyping. Preliminary approval to run at Yemilab in South Korea has led to the completed excavation of caverns. While the accelerator is designed to run underground, IsoDAR accelerators can also be constructed on the surface, allowing this project to contribute to the opportunity for production of life-saving medical isotopes. The capabilites, technical elements, and deployment studies are well-documented in articles on arXiv, and appear in multiple Snowmass'21 whitepapers. Rather than repeat this text, this whitepaper provides a "table of contents" to these documents.
