we succeeded in starting test of vacuum vapor deposition
equipment for TAO (Φ6.5m)

The 6.5m primary mirror vacuum vapor deposition equipment
at the University of Tokyo Atacama Observatory(TAO) was successfully completed.
We conducted assembly work and start-up tests in Japan from January to April 2020,
and confirmed that it is possible to form a coat of aluminum
that can be used as a telescope.
