Query: Dark matter Axion search with riNg Cavity Experiment DANCE: Development
  of control system for long-term measurement   Axion-like particles (ALPs) are pseudo-scalar particles that are candidates
for ultralight dark matter. ALPs interact with photons slightly and cause the
rotational oscillation of linear polarization. DANCE searches for ALP dark
matter by enhancing the rotational oscillation in a bow-tie ring cavity. The
signal to noise ratio of DANCE can be improved by long-term observation, and we
are planning a year-long observation for the final DANCE. In this document, I
will report on the control systems of the ring cavity we developed for the
future long-term observation.
