The high-finesse nanofiber-based cavity with fiber Bragg grating mirrors is a promising platform for cavity quantum electrodynamics (cQED), facilitating strong atom-photon interactions at the single photon level. While the reduced nanofiber diameter enhances the interaction, it leads to mechanical fragility and sensitivity to contamination. To overcome this, a proposed storage method involves a portable container filled with dry nitrogen gas, enabling on-demand installation into an ultra-high vacuum chamber. This separates fabrication and installation processes, while reducing optical loss during installation to less than 0.07%. The independent optimization of procedures positions this on-demand installation technique to propel advancements in cQED experiments with nanofiber-based cavities.
